The new Russian seems to have a bit higher gain and it sounds more transparent and airy. The NOS produces the classic focusing sound with a little warmer. Both are good in each own way.
Yeah i can hear the newer tubes just sound more modern, thats not necessarily better. I like how the old tubes reminded me of the past , the sound of the past. I would use either. But i honestly like the warmth the old ones have ;-)
There is nothing airy and thin in real acoustics (from a UN-amped instruments). I will say some do like this however it's not at all realistic (no tonality).
@@mikemoyercell JJ in Slovak Republic isn't a bad option. If you hunt about, there's dealers that have soviet surplus tubes you can buy too. The EH family of tubes are available, just too pricey.
Excellent comparison and editing of this for our enjoyment! I’m easily going with the Red based, Russian tubes for sure. Just close your eyes when listening and you will hear the midrange and treble change :)
Its interesting to here the slight difference for my ears the NOS are nicer, the new ones sound boxed in on vocals, thanks for this test, it is nice to know that the new tubes still do a good job for the price I would still buy.
I was prepared to proclaim NOS as unbeatable before the demo started. After listening twice now I'm leaning more to the new. I feel like the top end has more air to it. The cymbals had more decay before they disappeared. IMO they both sound great and a huge thank you for talking the time.
I have a question, doesn't checking the tube bias and the current balance for each "pair" count? Is the amplifier auto biasing. Also, how many high power hours of operation were used to "break them in". For new tubes, I carefully adjust the bias, then check it again after some operating time (100 hours?). Sometimes there is a notable change early on, then it's pretty stable after that.
Great video production. Thanks for sharing this with us. I enjoyed both tubes. The difference is subtle but apparent. It’s impossible to say either one is better. It’s a matter of your set up and preference.
Great video! I have both and I like them all, but my fave is the NOS. The new Tung Sols sound a bit metallic for my ears. My system includes a 1978 Kenwood KA-9150 amp running the new Klipsch 600M II and the NOS Tung Sols really take the edge of those often too bright speakers
I observed the same thing, however, I actually like the full more forward sound of the new Russian tubes, even though they aren't quite as "crisp". For long listening, I like the mellow sound of the new ones.
@@TycoDogg I can definitely hear a difference between the JJ's and the JFET setting, Even the wife could tell, So I'll post my findings with the TS's once I have a few hours on them on my system. If its not what I'm looking for maybe I'll try some EH's.. Also the TS'c are the Russia flavor dated 07-02 ...
Here are my quick thoughts about this listening test. I really like the smoothness of the high frequencies coming from the American Tung-Sol tubes. There was no hint of edginess or harshness in the vocals in Suavecito and the presentation was very natural and neutral. This is in contrast to the Russian Tung-Sol tubes, which added a subtle but noticeable brightness to the vocals and percussion that was apparent in the 2nd song. As I mentioned before, the JBL 4343s use compression drivers in the high frequency and ultra high frequency speaker components that are very sensitive to high frequencies. They do not need any additional brightness coming from the tubes. For me, the Russian Tung-Sols sounded fatiguing to me through my JBL 4343s. If you have speakers that are more laid back or relaxed in the high frequencies, the Russian Tung-Sols may be a great option for you. As for the bass frequencies, the Russian Tung-Sols had more impact in the kick drum and bass guitar and seemed to bring the lower frequencies more forward in the soundstage. However, the American Tung-Sol's bass sounded more balanced and rounded to me. As for midrange, the American Tung-Sols just sound so smooth and controlled. They remind me a lot of the CBS-Hytron 5692s when it comes to midrange and high frequency presentation.
this is what i was hearing too. at first i was thinking that the russian had more high end and clarity, it does have more highs and a crispy tzzztzzzztzzzz thing going on but after going back and forth and hearing both i truly like the tone warmth and more balanced sound of the usa they sounded more spacious and natural.the russians sounded a tad brittle. at least thats what i thought listening on computer speakers on a compressed youtube video, i might feel differently if i was in the room?
The smoothness and restraint of the NOS tubes, particularly in the Smiths selection, makes them a better choice for most vocal listening. The Russian tubes are simply too bright, sacrificing overall quality of reproduction for a very clear, almost digital sound. However, that being said, that may be intentional on their part, with many audiophiles now preferring that sound bias. I wouldn’t throw either set of tubes out of bed for eating crackers.
Excellent comparison video. On my Audience The One speakers, I found the Russian tubes to be more open with greater treble definition. Midrange was also more open on the Russian tubes and the bass was more distinctly presented. Having said that, it would be totally system dependent. If I owned B&W speakers or brighter sounding gear in general, I might prefer the NOS.
Listening to this through nice gear the vintage Tung-Sols are slightly more pleasing smother and natural sounding. The new reissue tubes have a slight edge and grain to them. The Russian Tung-Sols are outstanding tubes and a great value.
1st off, thank you sir. Fine comparison and choice of music. I'm drawn to this by way of guitar amplification. My admittedly battered ears can hear more content with the new offerings. On the live cut I can actually hear crowd banter which simply isnt there with the vintage set. But, that vintage bass tho! Almost a modern R&B flavor bass. I could hear the bass better with the new tubes but, could FEEL it better with the vintage set. I'm getting the new ones for my rig as I dont play bass. Thanks again friend!
Thanks for making this video. I use modern made Tung-Sol 6SN7's in my Freya+, replacing the JJ tubes it came with. I welcome this comparison, but I think micing your speakers makes it very hard to really compare them. The particular loudspeakers and amps (good as they are) contribute sonics and the room is also very apparent in the audio. Better to pull a direct output from the Freya to a high quality AD convertor and post comparisons that way. Just a suggestion, and thanks again for posting this.
Very nice clip! Both sound magnificent! I use and recommend the New Sensor TS pretty much across the board. Very high quality. These Russian TS's have more clarity/spaciousness with the mid-high end tone while the vintage TS presents more low...of course an internal component mod can change that to some degree. I build n modify hiZ bullet microphones and modify only tube amps for us harmonica players where the ear is extremely important to achieve good amplified tone with rich n spacious tone before and at the clipping point . Having said that about the mid-highs of the Russian Pre TS, my favorite 6L6 is the new Tung Sol 6L6GT STR with its tight and punchy low end. When I AB verses my stash of prime NIB 50s n 60s RCA 6L6s the new TS STR in my opinion out performs my RCA's. I really like the new TS Russian built tubes. Note: The new Mullards are made at New Sensor and sound like TS and look nearly identical to the TS, however, I've had 6L6 Mullards show up with crooked bottles while the TS's are built with attention to detail and a little cheaper....2 different New Sensor plants. But now tthe Mullard "preamp" tubes are very very good just like the TS's. IMO you can't go wrong with new TS.
@@TycoDogg Many thanks, Tyco!! Hoping it's a 'good version' as 07 02 seems to be the most prolific on the internet, or are they exactly the same, if you don't mind me askling?
They both sound pretty good but I much preferred the NOS. Especially in the 1st track. This is listening over my phone though and I don’t like judging critical sound through a UA-cam video either. Always so many variables to audio. The newer sounds brighter to me and a bit hollow on the top end. The mid and lower lose a bit of their oomph and warmth compared to the NOS imho. That’s just me though. I’m new to trying to listen for these things so... be gentle 😝
Hi, i need some advice from you about the 6sn7 tubes as i am new to tube rolling. 2 questions; 1) I will be buying darkvoice amp and it says 6sn7 on the top plate. Since there are gta and gtb versions, can it be used in the DV? I believe gta/gtb version have higher power output and would it destroy the amp circuitry or anything like that? 2) Since tubes are expensive, i can't test out lots of brands straight away. I want to start off with one/two base line tube that's more neutral but has a kick to the bass and mids. I love soundstage, if there's a tube that can accentuate this, it's a bonus. My headphone I'll be using is Beyerdynamic DT990 600 ohm and Sennheiser HD650. Since my DT990 has high treble by default, i don't want a tube that accentuates the treble. Can you recommend me two/three tubes as a base line to try out this magical tube world. Thank you and great job on the video. No one in youtube has down what you are doing.
Hi Alex, thanks for the compliment! I haven't had any issues exchanging 6SN7 GTA and GTB tubes. You may want to confirm with the manufacturer to be sure. My JBL 4343 studio monitors are also extremely revealing in the high frequencies and I do not like an overly bright sound. For this reason, I love the smoothness of the CBS Hytron 5692s made in the late 1950s. Can't go wrong with the sound from these great tubes. The Sylvanias also have a solid midrange and smooth highs, and they may be easier to find. New production Tung-Sols have that kick in the low frequencies that you desire, however, they're also brighter on the high end, which I don't really care for in my system. Best of luck on your tube rolling journey!
Tyco Dogg Wow, the price for the cbs is quite expensive. You liked the shuguang treasure cv181 too right. I can get that a third of the price of the cbs which is within my budget. Can you comment on the characteristic of the shuguang treasure tube? Thank you
alexbarquin9 look in the comments section of this video for my thoughts on the Shuguang black treasure tubes. They are my favorite new prod. Chinese tube. ua-cam.com/video/NtL4jIEgfSc/v-deo.html
Tyco Dogg I might give the Shuguan Treasure tube a go based on your review. Does it need any burn in time and how long? My other question is that are you able to explain power tubes on what it does? Would it make sound different like a preamp tube does? I found a hytron power tube for sale and since you loved the cbs hytron preamp tube i might give it a go. What do you think?The 6AS7 power tubes that i found so far are the RCA, GE, Sylvanias, Ratheon and some other brands. Any recommendation? This is what confuses me what to choose and there's little facts about power tubes in the net. People just talked more about preamp tube. Thanks man
You can't go wrong with the Shuguang Black Treasures. They are well matched right from the factory, it seems. If I had a quad of the Shuguangs, they would make a regular rotation on my Freya preamp. I know many "experts" claim tubes need a break-in period. One of the tests I plan to do is make a reference recording of a brand new set of tubes, then break them in for 200 hours or so, and then repeat the reference recording and do an A/B comparison. I believe this would be the only objective way to really see if a difference can be heard. Since I do not use a tube power amp, I can't comment on power tubes except to say that the "tube sound" is based on driving your tubes to the point of non-linearity, at which point the even-order harmonics are generated. I would think it's a lot easier to overdrive a preamp tube than a power tube, but that's just my guess.
It is really difficult to say anything while I am listening on my Genius computer bar speaker :-) Only one who can say anything is you 'cause you are listening directly :-)
The USA old stock ones sound more tinny and narrower in sound, whilst the Ruski new ones have a wider sound like they have a bit of reverb and a nicer tone.
If you prefer a brighter sounding tube, the new production Russian Tung-Sol might work for you. My only recommendation is to pay the extra few bucks to get a platinum grade Tung-Sol from Upscale Audio. They are tested for triode balance and microphonics.
Tyco Dogg im already using the 6sn7gtb stock tubes and I really like the sound. I will check the platinum one . Is there like a model number? Im really new in tubes. Thanks!
Thanks, the power amps I use are two Crest Audio Pro 5200s in bi-amp configuration. They are touring-class amps, mainly used in concert venues, and are American-made Class AB 2-channel amps with balanced inputs. My background is pro audio/video and I've used Crest Audio amplification for many years, so I like to run equipment that I have experience with. One 5200 runs the 15" woofers in the JBL 4343 monitors, and the other 5200 runs the mid/high/ultra high drivers via the stock passive network.
Thanks Anthony! All that matters is what your ears tell you. I wouldn't worry about the opinions of others (including myself) when it comes to this hobby of ours. Check out my Tesla tube listening test and see if you can hear a difference. If you can't hear any difference, spend your money elsewhere and enjoy the music.
@Tyco Dogg yeah..I know. $$$! just bought a matched pair of Soviet made True NOS 6N23P-EV 6922 type today for just over $100. Not sure what I am doing but forging ahead.
The NOS do sound better.. more realistic and immersing, but honestly for the money the Russians sounded pretty good. I think for a pre stage I’d spend for the nos but for power I’d go with Russian.
I use the new Russian Reissue Tung Sols in my set up. I have NOS USA ones also, but they just can't hang with the new. Listening to both thru my Klipschorns, the new tubes deliver more bass, mid bass and dynamics with more punch than the NOS, which also comes thru listening to both on your video even thru UA-cam. Thx for making the great audition video and posting it. Thoroughly enjoyed and confirmed what my ears already knew.... the new Russian reissues are nothing to sneeze at
First off,nice selection of songs especially the second song,I don't know the worth of the USA made NOS Tungsol but im sure they would be much more expensive than the Russian made,but I like both,but just a little more in the Russian made Tungsol
Why don’t you check the total harmonic distortion and frequency response with the 2 valve types I seem to remember the 3rd harmonic is what to look for in a valve amplifier
The New Russian tubes have a hollow metallic sound on the highs (tinny), however, appears to produce more pronounced bass. I suspect they are more responsive to low frequencies, while the old American tubes are well rounded. The 1950s was the peak era for tubes, therefore, we can expect NOS from that time to be of high quality. However, the Russian tubes are very good, and are top quality.
Wow. Russian tube are absolutely outstanding. What a sound image and openness. Relaxed, wide, in higher frequency. Very detailed. Very tight bass and clear middle register.
I would be happy with either. NOS seem to compress a bit more. Russian ones more Open sound I would prob prefer on the long run. Wonder how they would go In a guitar amp
Most every tube I've got made by Reflector C.O. sounds impressive. Their 5881WXT is hands down my favorite current production 6L6 type tube. The one and only problem is they don't last long. but at the same time one should consider how often you use the system/ device you put them in. if you don't use your amp/ sound system very often then they last a long time. If your going for any Russian/ Eastern block type tube and you find some that you really like, my advice would be to buy another set when you have some extra money and put them on the shelf (after testing them) . Right now tube companies are having a hard time staying open. someone told me Svetlana shut down. and I hear Winged =(C)= is gone also. I would not be surprised if say 5 years from now the only Tube production left would be in China. Having said that. I have never bought any 6SN7 tubes. but to my ear the US Tung-Sol has a little less treble. US Tung-Sol tended to make their output tubes with "noise suppression" built in . it works good but you lose some top end/ treble. The US Tung-Sol 5881 is to me the most "noise suppressing" of all. but they kill the treble and harmonics (to my ear anyway) If I wanted a US made set of 6SN7's I'd choose in this order RCA, CBS Hytron, GE, Sylvania. ( dependent on availability and price) . Again, I have never bought 6SN7 tubes . I'm just going by my previous experience with output tubes.
For someone going on 28 who can still hear CRT whine American tubes : sounds slight bit lower with more clean audio Modern Russian Tubes : Louder, warmer, more range, but a bit more muddled, while the music sounds warmer and inviting, the lyrics sound just a tiny bit more muddled but nothing to be super antys about. MIND YOU. I have good hearing but I have little BIAS for HIFI stuff, I'm still happy if something sounds like a VHS copy of a sound track, so long as I can hear the lyrics.
I normally don't like listen tests because you are hearing your own system. I admit that to me the modern ones sounded better(Some one below called it more modern), but I listened through 6L6GC in my Prima Luna and frankly nether sounded near as good as the smiths album played directly.(FYI I saw them live when he was still wafting about the carnations, if I remember properly) I am very interested in your descriptions, advice and grater experience etc but but I'm sceptical of direct listen. I am actively looking for new valves to experiment with as so far I have only heard the original Prima Luna EL34's and the above mentioned HARMA retro which I would recommend to anyone interested. I have just subscribed and hope to learn more about valves.
Trust your own ears, not anyone else's (including mine). As for hearing your own system, that is the whole point of my channel. No matter what preamp, tube/valve, cables, etc you have, your ears are ultimately hearing the music as it comes out of your transducers (whether those transducers are headphones or speakers) travels through your listening space and hits your ear drum. It's all about how your system sounds in your environment and whether you enjoy it. Cheers!
Nice video, my opinion, the new russian tung sol sounds more bright, a bit more detailed, the sounds looks more open, wide, the NOS us, the sounds looks balanced, neutral, both good, but I will choose the Russian, I got the EL34B russian tung sol and they sounds absolutely great!
Both are fantastic tube..usa tube is bright clear sound..and russian tube is full bodied warm airy sound..but I prefer both.🙏🙏🙏very good video.Thank you.
I think both are very good. You can choose better match for you depending what you look for. The good news is that new production insn't any whorse than NOS.
Sou tecnico de eletronica aqui no brasil , cheguei a concertar muitos aparelhos valvulados eram uma maravilha de aparelhos e muito bem fabricados qualidade insuperavel .
To me the Russian tube seems to offer a "fuller" sound. The NOS is perhaps slightly more detailed but just by a hairs breadth. The Russian tube to me offers a fuller reproduction across the frequency spectrum. There's just more there, there. Given a choice, I would take the new tubes over the NOS hands down.
Listening through my Russian 20 01 latest production in my Freya +.. I think Russians are more analytical with more presence though the American are more reminiscent of actual tube warmer sound..
It’s a comparison of old vs new...... the 322 were made for sound on 1950s music and music equipment and of course the new ones for now. If there was anyway for you to acquire a music system from that era to compare the sound ,that would be very interesting to hear the comparison and truly appreciated. Thank you , great videos 👍🏻
DT-770 headphones, cheap standard laptop on board audio. Was surprised to hear such a difference. I was hoping the newbies would be better but I think not. Nothing wrong with them, just preferred the Tung-sol. I can understand why many like the new stock. They also give the allusion of higher gain. But a careful listen leads me to think the mix is less defined with the new stock. Still, the new stock sounds good and I wouldnt hesitate giving them a run. Scared to think what a quad set of NOS tubes cost.
watching these vids is better than watching the yule log on xmas day on tv. i don't notice any difference maybe it's the equip - schiit modi 2 uber & vali 2 with ECG7EH tube - beyerdynamic dt-880 pro. prolly just my ears -- i just ordered a russian made tung-sol 6SN7GTB - i don't really know what i'm doing - good video
Thanks MaltLiquor45! The new production Russian Tung-Sols sounded practically identical to the solid state mode on the Freya in this listening test I did: ua-cam.com/video/1Slu3u0o4Aw/v-deo.html In my experience, I really didn't begin to hear anything other than subtle differences between tubes until I started listening to NOS 12AU7 and 6CG7 tubes like the Telefunken and Tungsrams (which are my current favorites in terms of tube sound). Also, as far as using headphones, they are great for critical listening, but not so great for soundstage in my opinion (I use a set of Audeze LCD-2 headphones which sound great, but the soundstage collapses around your ears and not in front of you). I recommend using a good set of studio monitors (I use a pair of Yamaha HS80Ms and HS8S sub) if you're listening via your computer, or connecting your computer's output to your 2-channel stereo system and listening that way.
Apparently this is a new fashion ... determine the sound quality over the Internet. What quality can I talk about? :) For me, this is nonsense ...Sorry for the bluntness of my judgments .
Well, it is not that much where they were made, but how old they are. With something degrading with time and designed to last just few years of shelf life, I would preffer the new ones than those many decades past their due date. Not because of the silly sound compare here (I can not get, how such a heavily compressed sound on YT may ever be of any use for any listening test), but just gecause of the expected reliability...
Sweet video. I think both sound good. I think the bass from the NOS sounds a bit tighter and punchier. The brightness of the Russian tubes might be preferable in some songs though. And as other have mentioned, they could sound better after burn-in.
Definitely Russians Has Lots Of Blood Bone Talents & Fantastic Skills For Vacuum Tubes Technologies Than America & They ( Russians ) Is The Most Advanced & Sophisticated Vacuum Tubes Invention Country Of Planet Earth & Their KT-150 Super Annoyed Vacuum Tubes Performances & Qualities Are Stunning & Unmatched With Any Other Tubes Making Countries.......
Great video. I buy new tubes. I’ve been told I’m waist int my money as 1960 NOS are the only way. BS I say. I’m currently using MULLARD reissue that sound great.
When it comes down to it, only your own ears will reveal the truth as you hear it. Trust what your own ears are hearing over what anyone says, including myself. Thanks for listening!
looks like they have slight different electrical specs. (which very likely is due to different mechanical design noted at first sight). that could explain the higher gain in hi freqs... to be fair.
The difference using Senheiser phones was minimal to me! The new tubes sounded say 2 db louder in parts but it wasn't a massive diference! If you could only get the new Tung Sole tubes, it wouldn't be a total audio tragedy! They both sounded the same 98% of the time! I own a Primaluna Dialogue Premium HP Integrated Amplifier and the EL34 output valves sound excellent! The only difference between the EL34 tubes and say some KT-120s was ouput power! There have been quite a lot of NOS failures actually! The filaments are the weak link. No power for 50 years then bam, wake up and sound superb while you're at it! I have also seen new KT88s 120s and 150s with open filaments on some UA-cam restorations but the seller was quite happy to swap them over at his expense! Our love of tubes or valves as we call them here in Australia is borderline senile dementia lol! I have 4 tube amps! A Leak Point One Stereo system I have is being restored. The pre-amp is in first class condition in looks and operation as is the amplifier itself! We dabble in this obsession of ours at our financial risk! That is all! LOL An Australian attempt at humour!
Hi Andrew, thanks for sharing your insight about your tube experience! I agree this particular test didn't have a huge audible difference, based on my memory. However, my latest test with the TESLA tubes had a much different outcome. I'm curious to have you take a look and let me know your thoughts: ua-cam.com/video/Zbe6QqQ9ii4/v-deo.html
Red base: More bass, less "defined". Black base: More clarity, possibly to much in the top end (fatiguing). But that is with my ears and my headphones. And my preferences. Think an inbetween tube would be best.
The russian ones are more warm and lush sounding, the american made one is while still lush in comparison to modern solid state amps is more bright and dryer. Both have that saturation in dynamics I expect from a tube that makes them appealing and makes youtube sound a bit higher resolution than it really is. I don't know in a situation like that I think I'd have to own both. They both serve a meaningful purpose.
Goforitmanager try this on some actual audio equipment. You will hear a difference. I'm using with KEF q750's, Sony 1100ES amp, and JL D10 sub. I like the Russian tubes a little more - more open and better low end bass.
Maybe I am not familiar with the music you're playing because I didn't look when you switched and really could hear no changes. Not enough to make any difference.
Just like when fender tube amps are compared to tonemaster amps. I don't hear any difference. This test is good, as new tubes are many dollars cheaper than very old (NOS) tubes. Chinese tubes? Not sure about them, as the Chinese are known to cut corners (cheat) when producing their products in general. But I haven't heard a comparison between all 3 types yet. So far, just like with old guitars, compared to the same type of new ones, I feel that the difference is in the mind not the ears. "Placebo". As long as the quality is equal. Very interesting demonstration. Love the music. Thank You
The black (USA) sounded more tingy. they had a hot spot right around 8 kHz. The orange (Russia) sounded fuller, and didn't have that hot spot on the highs. The midrange is much better on the orange, but, they're not as strong in the highs. I can't say one is better than the other, but, I prefer the Russian tubes in this amplifier. I'm surprised there's that much difference. There might be something to "rolling tubes".
The difference to untrained ear or someone who wasn't expecting it is minimal. But, you can her American ones are a bit muted. Not much. The Russians are a bit brighter sounding. I like both!
Actually it is very difficult to describe as it is very much depends on the personal preferences more over the small signal triodes are more or less same as nos the NOS power tubes such as 6L6 GC 6V6 EL34 etc are more durables at higher anode voltage and also long-lasting ones .But NOS power tubes are very costly incomparison with the new productions and it is great that the vaccum are still in production.
The Russian tubes sound a bit grainy compared to the smoother NOS. This gives the impression that the Russian tubes yield more detail. However and as was noted by the others, this graininess might go away with more burn-in time. Are both sets of tubes fully burned in already? If not, this excellent demo might not be a fair comparison of both sets.
In the beginning when the difference was very noticeable, I preferred the NOS which was much "fuller" sounding. Later, I couldn't tell the difference, but towards the end, I actually preferred the Russian version.
The new Russian seems to have a bit higher gain and it sounds more transparent and airy. The NOS produces the classic focusing sound with a little warmer. Both are good in each own way.
Yeah i can hear the newer tubes just sound more modern, thats not necessarily better. I like how the old tubes reminded me of the past , the sound of the past. I would use either. But i honestly like the warmth the old ones have ;-)
There is nothing airy and thin in real acoustics (from a UN-amped instruments). I will say some do like this however it's not at all realistic (no tonality).
Yes they isn't understand how to tuning valve, they like American be better than russinen, its American video.
New production tubes are nothing to sneeze at. It's nice to have quality tubes still made for audio projects.
yeah it was till putin went nuts...
@@mikemoyercell JJ in Slovak Republic isn't a bad option. If you hunt about, there's dealers that have soviet surplus tubes you can buy too. The EH family of tubes are available, just too pricey.
@@mikemoyercell Are you really that stupid?
@@mikemoyercell
Putin was not going to go crazy. The most sober politician in the world. Take a closer look at Biden and Trump.
Excellent comparison and editing of this for our enjoyment! I’m easily going with the Red based, Russian tubes for sure. Just close your eyes when listening and you will hear the midrange and treble change :)
The name of this vid is so specific and alienates all who don't understand the terms. I love it
I am slowly moving all my 6L6 guitar amps over to the current Tung-Sol 5881's. I love the clean, tight basses they provide.
Maybe it's my phone. Maybe it's UA-cam. I hear no difference. Both sound good. And yea, its good that these are still made.
Use headphones
Its interesting to here the slight difference for my ears the NOS are nicer, the new ones sound boxed in on vocals, thanks for this test, it is nice to know that the new tubes still do a good job for the price I would still buy.
I was prepared to proclaim NOS as unbeatable before the demo started. After listening twice now I'm leaning more to the new. I feel like the top end has more air to it. The cymbals had more decay before they disappeared. IMO they both sound great and a huge thank you for talking the time.
Thanks Terry, I appreciate your thoughts on the listening test!
Wait until you get 5000 hours on them , then compare them .
I have a question, doesn't checking the tube bias and the current balance for each "pair" count? Is the amplifier auto biasing. Also, how many high power hours of operation were used to "break them in".
For new tubes, I carefully adjust the bias, then check it again after some operating time (100 hours?). Sometimes there is a notable change early on, then it's pretty stable after that.
??????
Great video production. Thanks for sharing this with us. I enjoyed both tubes. The difference is subtle but apparent. It’s impossible to say either one is better. It’s a matter of your set up and preference.
You editing is awesome.
Thank you!
The black one sounds cool and dark background, the brown one sounds mellow and clear background. I like the brown one, cause it has more flavor to me.
Fascinating history on the TUNG-SOL tube company.
Great video! I have both and I like them all, but my fave is the NOS. The new Tung Sols sound a bit metallic for my ears. My system includes a 1978 Kenwood KA-9150 amp running the new Klipsch 600M II and the NOS Tung Sols really take the edge of those often too bright speakers
Thanks! You should try NOS Sylvanias, they are great with horn loaded drivers to help balance the brightness.
@@TycoDogg Already on their way after watching more of your videos. Thanks! (I use a tube buffer,)
The NOS is more airy, and the newer one is more forward sounding to me. For long listening, I would prefer the NOS. ;)
Idk, that transition after 7:00 suggests otherwise. The Russians sounded a lot more "airy" there in my opinion.
You have it backwards. The Russian tubes are much airier.
@@brx360x You have it right.
Yep backwards, the Russians sound more airy.
I observed the same thing, however, I actually like the full more forward sound of the new Russian tubes, even though they aren't quite as "crisp". For long listening, I like the mellow sound of the new ones.
I preffer the Russian's. Thanks!
Top end of the real Tung Sol's are smoothed out. They sound softer
Just ordered a quad matched set of the Tung Sol's, for the Freya + . It will be interesting to hear the difference from the stock JJ valves ....
Nice! I've found the new production Tung-Sols to sound identical to the JFET mode on the Freya.
@@TycoDogg I can definitely hear a difference between the JJ's and the JFET setting, Even the wife could tell, So I'll post my findings with the TS's once I have a few hours on them on my system. If its not what I'm looking for maybe I'll try some EH's.. Also the TS'c are the Russia flavor dated 07-02 ...
@@moon-light1354 there is a gain difference between tube and JFET modes in the Freya, so you'll need to account for that.
I think the newer one is a little nicer. Great video, thanks for sharing.
i am too
Here are my quick thoughts about this listening test. I really like the smoothness of the high frequencies coming from the American Tung-Sol tubes. There was no hint of edginess or harshness in the vocals in Suavecito and the presentation was very natural and neutral. This is in contrast to the Russian Tung-Sol tubes, which added a subtle but noticeable brightness to the vocals and percussion that was apparent in the 2nd song. As I mentioned before, the JBL 4343s use compression drivers in the high frequency and ultra high frequency speaker components that are very sensitive to high frequencies. They do not need any additional brightness coming from the tubes. For me, the Russian Tung-Sols sounded fatiguing to me through my JBL 4343s. If you have speakers that are more laid back or relaxed in the high frequencies, the Russian Tung-Sols may be a great option for you. As for the bass frequencies, the Russian Tung-Sols had more impact in the kick drum and bass guitar and seemed to bring the lower frequencies more forward in the soundstage. However, the American Tung-Sol's bass sounded more balanced and rounded to me. As for midrange, the American Tung-Sols just sound so smooth and controlled. They remind me a lot of the CBS-Hytron 5692s when it comes to midrange and high frequency presentation.
Yeah I agree. I have the new Tung Sol tubes and they are definitely a little bit harsh in the high frequencies.
this is what i was hearing too. at first i was thinking that the russian had more high end and clarity, it does have more highs and a crispy tzzztzzzztzzzz thing going on but after going back and forth and hearing both i truly like the tone warmth and more balanced sound of the usa they sounded more spacious and natural.the russians sounded a tad brittle. at least thats what i thought listening on computer speakers on a compressed youtube video, i might feel differently if i was in the room?
The smoothness and restraint of the NOS tubes, particularly in the Smiths selection, makes them a better choice for most vocal listening. The Russian tubes are simply too bright, sacrificing overall quality of reproduction for a very clear, almost digital sound. However, that being said, that may be intentional on their part, with many audiophiles now preferring that sound bias. I wouldn’t throw either set of tubes out of bed for eating crackers.
@Mufasa Excellent point
I replaced a worn set of old 6550 with a new production set and the sound was awesome. They nailed the 6550 tubes.
Excellent comparison video. On my Audience The One speakers, I found the Russian tubes to be more open with greater treble definition. Midrange was also more open on the Russian tubes and the bass was more distinctly presented. Having said that, it would be totally system dependent. If I owned B&W speakers or brighter sounding gear in general, I might prefer the NOS.
The newer tubes sound like they need more break in. I like both for what they do, would use both in rotation. Thanks for the compare.
And how or what do thing will “break in”
@@leonk7249 "break in" do thing sound will 300 hours better
Listening to this through nice gear the vintage Tung-Sols are slightly
more pleasing smother and natural sounding. The new reissue tubes have a slight edge and grain to them. The Russian Tung-Sols are outstanding tubes and a great value.
Going in I expected the NOS to win. But I liked the new ones more.
1st off, thank you sir. Fine comparison and choice of music. I'm drawn to this by way of guitar amplification. My admittedly battered ears can hear more content with the new offerings. On the live cut I can actually hear crowd banter which simply isnt there with the vintage set. But, that vintage bass tho! Almost a modern R&B flavor bass. I could hear the bass better with the new tubes but, could FEEL it better with the vintage set. I'm getting the new ones for my rig as I dont play bass. Thanks again friend!
Awesome, thanks for the kind words!
Just proves that being NOS doesn't automatically mean better quality. Slam dunk for the new kids on the block here.
Absolutely.
Thanks for making this video. I use modern made Tung-Sol 6SN7's in my Freya+, replacing the JJ tubes it came with. I welcome this comparison, but I think micing your speakers makes it very hard to really compare them. The particular loudspeakers and amps (good as they are) contribute sonics and the room is also very apparent in the audio. Better to pull a direct output from the Freya to a high quality AD convertor and post comparisons that way. Just a suggestion, and thanks again for posting this.
Which of the two Red or Black versions has a higher Sund-Stage? Is one of the two more Bright in the treble? Thank you
Very nice clip! Both sound magnificent! I use and recommend the New Sensor TS pretty much across the board. Very high quality.
These Russian TS's have more clarity/spaciousness with the mid-high end tone while the vintage TS presents more low...of course an internal component mod can change that to some degree. I build n modify hiZ bullet microphones and modify only tube amps for us harmonica players where the ear is extremely important to achieve good amplified tone with rich n spacious tone before and at the clipping point . Having said that about the mid-highs of the Russian Pre TS, my favorite 6L6 is the new Tung Sol 6L6GT STR with its tight and punchy low end. When I AB verses my stash of prime NIB 50s n 60s RCA 6L6s the new TS STR in my opinion out performs my RCA's. I really like the new TS Russian built tubes. Note: The new Mullards are made at New Sensor and sound like TS and look nearly identical to the TS, however, I've had 6L6 Mullards show up with crooked bottles while the TS's are built with attention to detail and a little cheaper....2 different New Sensor plants. But now tthe Mullard "preamp" tubes are very very good just like the TS's. IMO you can't go wrong with new TS.
I just bought a Darkvoice with a Tung-Sol 6SN7GTB with the label at the bottom 20 03. What does this mean?
That's the date code - year 2020, month 03 (March)
@@TycoDogg Many thanks, Tyco!! Hoping it's a 'good version' as 07 02 seems to be the most prolific on the internet, or are they exactly the same, if you don't mind me askling?
the sounds different is really subtle. Are all the tubes differences so subtle? I just ordered a Tung-Sol 6SN7GTB and
6AS7G RCA NOS for my amp
They both sound pretty good but I much preferred the NOS. Especially in the 1st track. This is listening over my phone though and I don’t like judging critical sound through a UA-cam video either. Always so many variables to audio. The newer sounds brighter to me and a bit hollow on the top end. The mid and lower lose a bit of their oomph and warmth compared to the NOS imho. That’s just me though. I’m new to trying to listen for these things so... be gentle 😝
The Russian tubes are more open, cleaner with better base.
An Obviously .......
Russian more bass and USA more focus.
Love your videos, I am looking at getting a Freya. Seems so versatile. Hope to be able to listen to more video.
Hi, i need some advice from you about the 6sn7 tubes as i am new to tube rolling. 2 questions;
1) I will be buying darkvoice amp and it says 6sn7 on the top plate. Since there are gta and gtb versions, can it be used in the DV? I believe gta/gtb version have higher power output and would it destroy the amp circuitry or anything like that?
2) Since tubes are expensive, i can't test out lots of brands straight away. I want to start off with one/two base line tube that's more neutral but has a kick to the bass and mids. I love soundstage, if there's a tube that can accentuate this, it's a bonus. My headphone I'll be using is Beyerdynamic DT990 600 ohm and Sennheiser HD650. Since my DT990 has high treble by default, i don't want a tube that accentuates the treble. Can you recommend me two/three tubes as a base line to try out this magical tube world. Thank you and great job on the video. No one in youtube has down what you are doing.
Hi Alex, thanks for the compliment! I haven't had any issues exchanging 6SN7 GTA and GTB tubes. You may want to confirm with the manufacturer to be sure. My JBL 4343 studio monitors are also extremely revealing in the high frequencies and I do not like an overly bright sound. For this reason, I love the smoothness of the CBS Hytron 5692s made in the late 1950s. Can't go wrong with the sound from these great tubes. The Sylvanias also have a solid midrange and smooth highs, and they may be easier to find. New production Tung-Sols have that kick in the low frequencies that you desire, however, they're also brighter on the high end, which I don't really care for in my system. Best of luck on your tube rolling journey!
Tyco Dogg Wow, the price for the cbs is quite expensive. You liked the shuguang treasure cv181 too right. I can get that a third of the price of the cbs which is within my budget. Can you comment on the characteristic of the shuguang treasure tube? Thank you
alexbarquin9 look in the comments section of this video for my thoughts on the Shuguang black treasure tubes. They are my favorite new prod. Chinese tube. ua-cam.com/video/NtL4jIEgfSc/v-deo.html
Tyco Dogg I might give the Shuguan Treasure tube a go based on your review. Does it need any burn in time and how long?
My other question is that are you able to explain power tubes on what it does? Would it make sound different like a preamp tube does? I found a hytron power tube for sale and since you loved the cbs hytron preamp tube i might give it a go. What do you think?The 6AS7 power tubes that i found so far are the RCA, GE, Sylvanias, Ratheon and some other brands. Any recommendation? This is what confuses me what to choose and there's little facts about power tubes in the net. People just talked more about preamp tube. Thanks man
You can't go wrong with the Shuguang Black Treasures. They are well matched right from the factory, it seems. If I had a quad of the Shuguangs, they would make a regular rotation on my Freya preamp. I know many "experts" claim tubes need a break-in period. One of the tests I plan to do is make a reference recording of a brand new set of tubes, then break them in for 200 hours or so, and then repeat the reference recording and do an A/B comparison. I believe this would be the only objective way to really see if a difference can be heard. Since I do not use a tube power amp, I can't comment on power tubes except to say that the "tube sound" is based on driving your tubes to the point of non-linearity, at which point the even-order harmonics are generated. I would think it's a lot easier to overdrive a preamp tube than a power tube, but that's just my guess.
It is really difficult to say anything while I am listening on my Genius computer bar speaker :-) Only one who can say anything is you 'cause you are listening directly :-)
The USA old stock ones sound more tinny and narrower in sound, whilst the Ruski new ones have a wider sound like they have a bit of reverb and a nicer tone.
cant tell which cymbals seems more natural to me....voice a bit more shrill with the ru tubes,..is it more natural ?
What tungsol tube can you recommend for the schiit lyr 3 amp?
If you prefer a brighter sounding tube, the new production Russian Tung-Sol might work for you. My only recommendation is to pay the extra few bucks to get a platinum grade Tung-Sol from Upscale Audio. They are tested for triode balance and microphonics.
Tyco Dogg im already using the 6sn7gtb stock tubes and I really like the sound. I will check the platinum one . Is there like a model number? Im really new in tubes. Thanks!
star gamer welcome to your tube rolling journey! There are so many choices. Be sure to check out my videos and read the comments - lots of good info.
Hey man, great comparison. What's the amp? and is it an integrated, or a poweramp only? Cheers
Thanks, the power amps I use are two Crest Audio Pro 5200s in bi-amp configuration. They are touring-class amps, mainly used in concert venues, and are American-made Class AB 2-channel amps with balanced inputs. My background is pro audio/video and I've used Crest Audio amplification for many years, so I like to run equipment that I have experience with. One 5200 runs the 15" woofers in the JBL 4343 monitors, and the other 5200 runs the mid/high/ultra high drivers via the stock passive network.
Excellent tests, very well done. I wonder if the Freya is capable of revealing the differences as distinctly as others I have heard.
Thanks Anthony! All that matters is what your ears tell you. I wouldn't worry about the opinions of others (including myself) when it comes to this hobby of ours. Check out my Tesla tube listening test and see if you can hear a difference. If you can't hear any difference, spend your money elsewhere and enjoy the music.
Hello, I noticed your tubes sit higher than the stock freya tubes. are you sing adapters? If so, where did you purchase them? Thanks.
I think these were the ones I purchased: www.partsconnexion.com/SOCKET-74489.html
Best headphone amp tube? ECC88, 6922 type
It's all subjective, but for me personally it's a vintage NOS Telefunken or Amperex E88CC. Too expensive for me though.
@Tyco Dogg yeah..I know. $$$!
just bought a matched pair of Soviet made True NOS 6N23P-EV 6922 type today for just over $100. Not sure what I am doing but forging ahead.
The NOS do sound better.. more realistic and immersing, but honestly for the money the Russians sounded pretty good. I think for a pre stage I’d spend for the nos but for power I’d go with Russian.
The Russian tung-sol sounded more hi fi and IMO they brought out more clarity than the NOS tubes.
I use the new Russian Reissue Tung Sols in my set up. I have NOS USA ones also, but they just can't hang with the new. Listening to both thru my Klipschorns, the new tubes deliver more bass, mid bass and dynamics with more punch than the NOS, which also comes thru listening to both on your video even thru UA-cam. Thx for making the great audition video and posting it. Thoroughly enjoyed and confirmed what my ears already knew.... the new Russian reissues are nothing to sneeze at
Questions I have EL34b can i put el34 on my system?
Yes just check the bias if it's a push pull amp personally l would stay with the el34b
First off,nice selection of songs especially the second song,I don't know the worth of the USA made NOS Tungsol but im sure they would be much more expensive than the Russian made,but I like both,but just a little more in the Russian made Tungsol
Excellent video. Do more like this?!
I would like this to be a blind test and then have people give opinions.
Why don’t you check the total harmonic distortion and frequency response with the 2 valve types I seem to remember the 3rd harmonic is what to look for in a valve amplifier
Sorry to say this but, I like the mothern. More detailed mid range be and top end. They sound brigher in a good way.
Mothern like Russian motherland
The New Russian tubes have a hollow metallic sound on the highs (tinny), however, appears to produce more pronounced bass. I suspect they are more responsive to low frequencies, while the old American tubes are well rounded. The 1950s was the peak era for tubes, therefore, we can expect NOS from that time to be of high quality. However, the Russian tubes are very good, and are top quality.
I think the old USA ones sound more hollow and tinny lol
what the name of song in beginning video
In the first selection, voice was slightly clearer with the Russian made tube. Second selection, it wasn't as noticable, (more voices???).
Exactly the same to me. I prefer the russian tube.
Wow. Russian tube are absolutely outstanding. What a sound image and openness. Relaxed, wide, in higher frequency. Very detailed. Very tight bass and clear middle register.
I'm a NOS guy but pleasantly surprised with the Russian tube's performance... I still like the NOS better though.
Great video... do some el34s
Cheers
I would be happy with either. NOS seem to compress a bit more. Russian ones more
Open sound I would prob prefer on the long run. Wonder how they would go
In a guitar amp
Russian tubes better and more forward midrange, just the way I like it. Great to see that there are great options to NOS. Good video.
Most every tube I've got made by Reflector C.O. sounds impressive. Their 5881WXT is hands down my favorite current production 6L6 type tube. The one and only problem is they don't last long. but at the same time one should consider how often you use the system/ device you put them in. if you don't use your amp/ sound system very often then they last a long time. If your going for any Russian/ Eastern block type tube and you find some that you really like, my advice would be to buy another set when you have some extra money and put them on the shelf (after testing them) . Right now tube companies are having a hard time staying open. someone told me Svetlana shut down. and I hear Winged =(C)= is gone also. I would not be surprised if say 5 years from now the only Tube production left would be in China.
Having said that. I have never bought any 6SN7 tubes. but to my ear the US Tung-Sol has a little less treble. US Tung-Sol tended to make their output tubes with "noise suppression" built in . it works good but you lose some top end/ treble. The US Tung-Sol 5881 is to me the most "noise suppressing" of all. but they kill the treble and harmonics (to my ear anyway) If I wanted a US made set of 6SN7's I'd choose in this order RCA, CBS Hytron, GE, Sylvania. ( dependent on availability and price) . Again, I have never bought 6SN7 tubes . I'm just going by my previous experience with output tubes.
For someone going on 28 who can still hear CRT whine
American tubes : sounds slight bit lower with more clean audio
Modern Russian Tubes : Louder, warmer, more range, but a bit more muddled, while the music sounds warmer and inviting, the lyrics sound just a tiny bit more muddled but nothing to be super antys about.
MIND YOU. I have good hearing but I have little BIAS for HIFI stuff, I'm still happy if something sounds like a VHS copy of a sound track, so long as I can hear the lyrics.
The Russian tung-sol sounded more flat but a bit clearer The NOS is a bit warmer and more ( agree with William Fong ) airy
Should test with all acoustic instruments .
I normally don't like listen tests because you are hearing your own system.
I admit that to me the modern ones sounded better(Some one below called it more modern), but I listened through 6L6GC in my Prima Luna and frankly nether sounded near as good as the smiths album played directly.(FYI I saw them live when he was still wafting about the carnations, if I remember properly)
I am very interested in your descriptions, advice and grater experience etc but but I'm sceptical of direct listen.
I am actively looking for new valves to experiment with as so far I have only heard the original Prima Luna EL34's and the above mentioned HARMA retro which I would recommend to anyone interested.
I have just subscribed and hope to learn more about valves.
Trust your own ears, not anyone else's (including mine). As for hearing your own system, that is the whole point of my channel. No matter what preamp, tube/valve, cables, etc you have, your ears are ultimately hearing the music as it comes out of your transducers (whether those transducers are headphones or speakers) travels through your listening space and hits your ear drum. It's all about how your system sounds in your environment and whether you enjoy it. Cheers!
Nice video, my opinion, the new russian tung sol sounds more bright, a bit more detailed, the sounds looks more open, wide, the NOS us, the sounds looks balanced, neutral, both good, but I will choose the Russian, I got the EL34B russian tung sol and they sounds absolutely great!
Both are fantastic tube..usa tube is bright clear sound..and russian tube is full bodied warm airy sound..but I prefer both.🙏🙏🙏very good video.Thank you.
I think both are very good. You can choose better match for you depending what you look for. The good news is that new production insn't any whorse than NOS.
Sou tecnico de eletronica aqui no brasil , cheguei a concertar muitos aparelhos valvulados eram uma maravilha de aparelhos e muito bem fabricados qualidade insuperavel .
Eu concordo. Há algo especial na maioria das coisas vintage.
To me the Russian tube seems to offer a "fuller" sound. The NOS is perhaps slightly more detailed but just by a hairs breadth. The Russian tube to me offers a fuller reproduction across the frequency spectrum. There's just more there, there. Given a choice, I would take the new tubes over the NOS hands down.
Well , WHAT about the price ? anybody can answer ? please !
Check ebay to get a rough idea of tube prices.
Listening through my Russian 20 01 latest production in my Freya +.. I think Russians are more analytical with more presence though the American are more reminiscent of actual tube warmer sound..
It’s a comparison of old vs new...... the 322 were made for sound on 1950s music and music equipment and of course the new ones for now. If there was anyway for you to acquire a music system from that era to compare the sound ,that would be very interesting to hear the comparison and truly appreciated. Thank you , great videos 👍🏻
DT-770 headphones, cheap standard laptop on board audio.
Was surprised to hear such a difference.
I was hoping the newbies would be better but I think not.
Nothing wrong with them, just preferred the Tung-sol.
I can understand why many like the new stock. They also give the allusion of higher gain.
But a careful listen leads me to think the mix is less defined with the new stock.
Still, the new stock sounds good and I wouldnt hesitate giving them a run. Scared to think what a quad set of NOS tubes cost.
watching these vids is better than watching the yule log on xmas day on tv. i don't notice any difference maybe it's the equip - schiit modi 2 uber & vali 2 with ECG7EH tube - beyerdynamic dt-880 pro. prolly just my ears -- i just ordered a russian made tung-sol 6SN7GTB - i don't really know what i'm doing - good video
Thanks MaltLiquor45! The new production Russian Tung-Sols sounded practically identical to the solid state mode on the Freya in this listening test I did: ua-cam.com/video/1Slu3u0o4Aw/v-deo.html
In my experience, I really didn't begin to hear anything other than subtle differences between tubes until I started listening to NOS 12AU7 and 6CG7 tubes like the Telefunken and Tungsrams (which are my current favorites in terms of tube sound).
Also, as far as using headphones, they are great for critical listening, but not so great for soundstage in my opinion (I use a set of Audeze LCD-2 headphones which sound great, but the soundstage collapses around your ears and not in front of you). I recommend using a good set of studio monitors (I use a pair of Yamaha HS80Ms and HS8S sub) if you're listening via your computer, or connecting your computer's output to your 2-channel stereo system and listening that way.
Apparently this is a new fashion ... determine the sound quality over the Internet. What quality can I talk about? :) For me, this is nonsense ...Sorry for the bluntness of my judgments .
@@viktordr6352 you can still hear differences. Not looking for sound quality just differences in presentation
With the old one, it's easier to hear all the parts. It's more enjoyable to listen to, for me.
The new ones are much more defined. Better mids, dont smear like NOS
The Russian made has more low bass & the midrange is more open (higher in gain?). Thanks for the video, well done👍
in my position... beggars cant be choosers. I trust new Russian rather than NOS USA. Just glad the Russians still make them!!!
Me too Mike. Russian is king of tubes. High quality
Well, it is not that much where they were made, but how old they are.
With something degrading with time and designed to last just few years of shelf life, I would preffer the new ones than those many decades past their due date. Not because of the silly sound compare here (I can not get, how such a heavily compressed sound on YT may ever be of any use for any listening test), but just gecause of the expected reliability...
Yeah I paid 40 bucks for a NOS 12ax7, absolutely love the sound, but it has gone microphonic really quick. Will try the new ones next time.
Sweet video. I think both sound good. I think the bass from the NOS sounds a bit tighter and punchier. The brightness of the Russian tubes might be preferable in some songs though. And as other have mentioned, they could sound better after burn-in.
Nice Vid. The first track showed clear evidence that the Russian tube sounded better.
Definitely Russians Has Lots Of Blood Bone Talents & Fantastic Skills For Vacuum Tubes Technologies Than America & They ( Russians ) Is The Most Advanced & Sophisticated Vacuum Tubes Invention Country Of Planet Earth & Their KT-150 Super Annoyed Vacuum Tubes Performances & Qualities Are Stunning & Unmatched With Any Other Tubes Making Countries.......
Great video. I buy new tubes. I’ve been told I’m waist int my money as 1960 NOS are the only way. BS I say. I’m currently using MULLARD reissue that sound great.
When it comes down to it, only your own ears will reveal the truth as you hear it. Trust what your own ears are hearing over what anyone says, including myself. Thanks for listening!
looks like they have slight different electrical specs. (which very likely is due to different mechanical design noted at first sight). that could explain the higher gain in hi freqs... to be fair.
The difference using Senheiser phones was minimal to me! The new tubes sounded say 2 db louder in parts but it wasn't a massive diference! If you could only get the new Tung Sole tubes, it wouldn't be a total audio tragedy! They both sounded the same 98% of the time! I own a Primaluna Dialogue Premium HP Integrated Amplifier and the EL34 output valves sound excellent! The only difference between the EL34 tubes and say some KT-120s was ouput power! There have been quite a lot of NOS failures actually! The filaments are the weak link. No power for 50 years then bam, wake up and sound superb while you're at it! I have also seen new KT88s 120s and 150s with open filaments on some UA-cam restorations but the seller was quite happy to swap them over at his expense! Our love of tubes or valves as we call them here in Australia is borderline senile dementia lol! I have 4 tube amps! A Leak Point One Stereo system I have is being restored. The pre-amp is in first class condition in looks and operation as is the amplifier itself! We dabble in this obsession of ours at our financial risk! That is all! LOL An Australian attempt at humour!
Hi Andrew, thanks for sharing your insight about your tube experience! I agree this particular test didn't have a huge audible difference, based on my memory. However, my latest test with the TESLA tubes had a much different outcome. I'm curious to have you take a look and let me know your thoughts: ua-cam.com/video/Zbe6QqQ9ii4/v-deo.html
Red base: More bass, less "defined".
Black base: More clarity, possibly to much in the top end (fatiguing).
But that is with my ears and my headphones. And my preferences.
Think an inbetween tube would be best.
Absolutely no difference heard with an iPhone with earbuds
LOL
LMAO. Try using some real headphones
@@luckyupyours That's the joke....... *Airplane noises*
I heard a distinct difference between them.
The russian ones are more warm and lush sounding, the american made one is while still lush in comparison to modern solid state amps is more bright and dryer. Both have that saturation in dynamics I expect from a tube that makes them appealing and makes youtube sound a bit higher resolution than it really is. I don't know in a situation like that I think I'd have to own both. They both serve a meaningful purpose.
Don’t think I can tell the difference on iPhone & Bose around the ear headphones.
Goforitmanager try this on some actual audio equipment. You will hear a difference. I'm using with KEF q750's, Sony 1100ES amp, and JL D10 sub. I like the Russian tubes a little more - more open and better low end bass.
Bah... give me a class C transistor amp any day. Clipping is cool! Distortion is the future! :-)
Maybe I am not familiar with the music you're playing because I didn't look when you switched and really could hear no changes. Not enough to make any difference.
Just like when fender tube amps are compared to tonemaster amps. I don't hear any difference. This test is good, as new tubes are many dollars cheaper than very old (NOS) tubes. Chinese tubes? Not sure about them, as the Chinese are known to cut corners (cheat) when producing their products in general. But I haven't heard a comparison between all 3 types yet. So far, just like with old guitars, compared to the same type of new ones, I feel that the difference is in the mind not the ears. "Placebo". As long as the quality is equal. Very interesting demonstration. Love the music. Thank You
The black (USA) sounded more tingy. they had a hot spot right around 8 kHz. The orange (Russia) sounded fuller, and didn't have that hot spot on the highs. The midrange is much better on the orange, but, they're not as strong in the highs. I can't say one is better than the other, but, I prefer the Russian tubes in this amplifier. I'm surprised there's that much difference. There might be something to "rolling tubes".
The difference to untrained ear or someone who wasn't expecting it is minimal. But, you can her American ones are a bit muted. Not much. The Russians are a bit brighter sounding. I like both!
Actually it is very difficult to describe as it is very much depends on the personal preferences more over the small signal triodes are more or less same as nos the NOS power tubes such as 6L6 GC 6V6 EL34 etc are more durables at higher anode voltage and also long-lasting ones .But NOS power tubes are very costly incomparison with the new productions and it is great that the vaccum are still in production.
Russian tubes nailed it
322? Illuminati confirmed.
The Russian version sounds more holographic to me. I dig it!
The Russian tubes sound a bit grainy compared to the smoother NOS. This gives the impression that the Russian tubes yield more detail. However and as was noted by the others, this graininess might go away with more burn-in time. Are both sets of tubes fully burned in already? If not, this excellent demo might not be a fair comparison of both sets.
Balance is off, to the right.
Not a problem on other vids.
Not a problem with the intro.
Thanks.
In the beginning when the difference was very noticeable, I preferred the NOS which was much "fuller" sounding. Later, I couldn't tell the difference, but towards the end, I actually preferred the Russian version.
