hi nice video good information tubes are great.dyanco 70 pas 3 was my first system hard to forget that tube sound take care.
I love this little amp, if you use very efficent speakers (or near field listening) it's unbeatable... amazing SQ!
Yes , Klipsch RP 600 M with this amp sounds indeed amazing 👍
I have been into tubes for a long time.(McIntosh, Heathkit,Pilot,Audio Research,Melos, Counterpoint,etc)....however,they were very expensive.i know! But the low priced Riesling A10 that I took a chance on has impressed me!! Out of the box,the amp looked great,but the tubes that were nicely wrapped,the rectifier tube and an input tube were broken.i happen to have tubes on hand,so I changed out the rectifier tube with a Tungsol(usa). reissued Telefunken EL34's,and nos input tubes.What a difference! Get rid of those chinese tubes asap! Beautiful sounding amp!
I have this amp paired with Klipsch RP-600M and Vincent SP-31 preamp. It sounds ridiculously good.
Hello can you help? Stupid question any help please. What Voltage do I need in California I do not know how to decide this. I am going to get this if I can figure out Voltage. Please help.

I have a set of r-51m speakers I was thinking of getting this and using those. They have a great sensitivity level like 93 or 94db I believe. They aren't as nice as your premier set, but I figure with my turntable going into my preamp, then into this and connect my r-51m klipsch out the back and hope it should be nice.
Dumb question but what are the speaker wire connectors on the back of this amp? Don't look like banana plugs because they have threads.
Forgive my ignorance.
@@2010stoof you can use both spade and banana
Some of these amps have point to point, some slightly cheaper ones are pcb. I made sure I got the p2p wiring. Very neatly wired. A beautiful amp that sounds nice....
Me as well.
bought this amp a year ago.its absolutely fantastic . it sounds as good as primaluna evo i also own.
What kind of speakers are you using?
Klipsch 600 also swap with martin logan aeon sorry for delay. I have swapped el 34 with kt 88 just shuguan little bit better
I have watched 3 videos reviewing this amp; no one yet have turned the damn thing on and played music through it!
It doesn't actually matter if they play it or not though, because you won't be hearing the amp play. You'll be hearing your amp that is playing your speakers.
@@TheCopperKidThanks for the reply , and I get the concept. But, would it not be interesting to hear about tube warm-up time, options for better tubes, volume? I did buy one, volume lacks greatly!!! hopefully the new Klipsch speaker on order will save this from my work bench for some major surgery
I love mine also. As far tube rolling I have tried the Tung Sol EL34s and found them to be a bit bright. They may need more burn in though. I am expecting a set of Telefunken EL34TKs this week and am looking forward to hearing those. If you are interested I will report back once those burn in. Telefunken does cryogenically treat the tubes and sells matched pairs. Also, I recommend the Schiit Mani phono pre-amp. It sounds very good. You didn't mention what digital sources you used other than the MAC book. If you use Tidal or Qobuz I highly and I mean HIGHLY recommend you try Audirvana. It can manage both your locally stored media and your streaming media in one interface. The key thing is that it is bit perfect playback and sounds remarkable.
Thanks for the recommendations! Yeah, I'd be very interested to hear back on your experience with the Telefunkens. I've heard from others that the Tung Sols can be brighter than the stock tubes. I'm planning to do some tube rolling in a month or two after evaluating a couple of external phono pre-amps.
How’d it go?
Ordered mine today. Really curious how it will sound vs my Mark Levinson solid state that does Class A for the first 8ish watts per channel.
I have the 300b and it it VERY good
I ordered tha A-12 and the only complaint I have is it appears that they included a used rectifier tube. Currently, no pun intended, driving a pair Sonus Faber Venere -S tower speakers rated at 4 ohms and it does a decent job at lower listening levels. I also have it connected to a subwoofer which gives me plenty of low end.
The tubes are quite sensitive to magnetic fields and to a vibration. I would put the cage back on, and put the amplifier on a vibration insulated stand.
also you get after sales support one year warranty in canada got fixed in wi usa i cant say enough highly reccomend buying any amp best price china hifi mr lee
I made a mistsake , i bought the PCB instead of the PTP version.But rhe sound is awsome for the price 👍
Nice turntable i have one muy self only in black.
Try pulling the Chinese tubes like I did.NOS input and rectifier tubes are recommended.i put re issue Telefunken EL34's in and the difference was night and day!!!.detail,soundstage,tonal balance made this amp sound like a 3,000 dollar amp.that is critical!!
$3000 amp???
I just purchased a BoyuuRange MT-34 MKII EL34 Tube Hi-Fi Intergrated Amplifier. You would recommend taking the tubes out and replacing with EL 34's?
Birthday gifts for oneself are cool.. And let's be honest, they are often the best.. Karma
He k yea, I fact cheched that and your spot on👍🏼
Another great thing (unlike other integrateds) is you can run an "External Preamp" into the rear if you so wish.. This is because this amp is technically NOT an Integrated amp. There are no preamp tubes. It is a 'Power Amp with Passive Volume control' same as Audion ( Single ended amps) or a Pro PA amp to cite another example... Normally you would never plug an external preamp into another preamp but this in this case is okay if you have a favourite preamp. Just plug it into the rca's set the Reisong/ Boyuu to 12 o'clock - 3 O'clock and control the level from your preamp.
Hello can you help? Stupid question any help please. What Voltage do I need in California I do not know how to decide this. I am going to get this if I can figure out Voltage. Please help.
@@hendrixpd1 what choices do you have choose from?
@@hendrixpd1 Probably 120 volts. But I'm in Canada and I checked the back of my Yamaha receiver and it stated 120 volts very clearly.
Bryan, Thank you for providing the answer that I was searching for. I have a pre-amp with a built in DAC and all the sources I need. So I was hoping to try the A-10 but was hesitant because it's labeled as 'integrated'. So I can come from the line-out of my pre into the line-in of the A-10 and use my pre-amp as normal.
@@roncochran4979 spot on Ron...Plug your Pre into the input of the Reisong...Yes, they still call it an 'Integrated' as to avoid confusion with the masses. We already have 'Mono Blocks' , Hybrid Amps, integrated, stereo power amps, etc...we don't need terminology for any more haha.
I’m interested in how this amp would work with my klipsch rf62-2 towers at 97db sensitivity. Any thoughts?
I don't have any experience with the Klipsch RF-62 IIs so I can't say for sure, but I imagine they would be a good fit based on their high sensitivity rating. I have a pair of older Klipsch RB-51 II bookshelves that I'm going to try with the Reisong at some point.
Those KEFs want tons of solid-state power.
LS50s work amazing at very high SPL with a PrimaLuna Prologue integrated tube amp. You have to spend a huge amount of $$ to get a similar level of SQ using solid state (Pass, Accuphase and above).
Great video. Thanks. Can you roll the EL34s with KT88s ?
Thanks for watching! I think it's theoretically possible to use KT88s in place of the EL34s on this amp, but I haven't tried myself. If you want to use KT88s, you might be better off upgrading to the slightly more expensive A20 which is designed to use them.
Try the KINKI that’s just been reviewed..power and precision
Nice video, i was curious about that amp too but afraid 6w wasn't enough for me.
I recommand the Atoll IN30 or IN100 (50w into 8ohm or 80w into 8ohm class AB) for the LS50. Great combo. or the integrated tube/solid state Taga harmony hta 700, only 25W into 8ohm but surprisingly powerfull. Works with 12ax7 (jj electronics ones rocks).
Thanks for the recommendations!
Depending on the sensitivity of your speakers, 8wpc can blow out your ears. Speakers like some Klipsch have a sensitivity rating of 100db. At 1 watt. 2 watts would be 103db (at 1meter).. 4 watts, 106db and 8 watts would be about 109db.. think your ears can take? This is all on paper of course.. but high sensitivity speakers need very little power to play extremely loud
How did you go "out" of the Receiver into the Reisong? Does the mitsubishi have a pre out or something? I have an Onkyo 5 channel and can't figure out how to use as a pre amp. Maybe I can't...?
I'm running one of the tape monitor line level outputs of the Mitsubishi into one of the line level inputs of the A10. The Mitsubishi does have a pre out which could be used with a power amplifier, but the A10 is an integrated amp (preamp is built in), so we just need a line level source.
Consider Emotiva BasX A300 for LS50 😎
Hi there, just like you I listen to tube amps years ago. Now 20 years later I wanted to hear that tube amp again. I bought a Nobsound 6p1to start with. I got it and hooked it up but that 6.5 watt just does not do it. Working in a steel plant for years my hearing just is not there . I have some active speakers that put out 1000 watts and it sounds great. I got on a site that said power + power = destruction so I stopped right there . I got on a site that talked about using a mixer and you can make this happen. The guy showed where to come out of it to the speaker but did not say ant thing about how to hook up the amp. Barenger 802. So do I need the mixer or does the 6.5 watt not matter as much?
Thanks for watching! Not sure, but I think your tube amp probably doesn't have a pre-amp out (same as the A10). I'm also thinking of getting a high watt Class AB amp soon, and will probably try to add some tube sound to it by using a Schiit Vali hybrid tube headphone amp in front (since it does have a pre-amp out).
My assumption based on specs is this would pair fairly well with Klipsch Forte IIIs? I don't run very loud and I have a big SS amp that drives them well. I wanna try a tube amp and this seems very low risk based on the cost.
I’ve never tried the Forte IIIs, but I imagine it would be a good match based on their high sensitivity and good reviews with other tube amps.
So you're using the "tape out/ record" output from your receiver that's at line level?
Yep, I'm just using the tape line level out from the receiver.
Stupid question anyone help please. What Voltage do I need in California I do not know how to decide this I am going to get this if I can figure out Voltage. Please help.
I'm new to this and wanted to understand how you connect your Mac to the A10. Does it go directly into the amp o do you run the signal through another device prior? For example, could I hook up my cellphone to the amp with a regular aux cable?
Thanks for watching. You could go directly from a Mac to the A10 using a cable with a 3.5mm jack on one end (connected to the Mac headphone out) and an RCA connection on the other (connected to the A10 aux in), but I wouldn't necessarily recommend it. The DAC built in to your Mac or phone is just so-so. A better solution is to get an external DAC like the Modi 3 used in this video to connect between them.
@@nadiraudio Hey man, thanks for your reply!
Is it possible to add a subwoofer to a two speaker set up? I don't see if the amp has a subwoofer output.
Alejandro Linares You can use the REL T5i for any amplifier as it connects directly to the speaker outputs and/or the subwoofer pre-out.
Alejandro Linares there is no subwoofer out on this one, but you can hook it up to a sub (or two) that has line-level inputs.
Could I plonk it onto my big solid state amp to basically....... Amplyfy the warm tube sound??
There isn't really a great way to do that with the A10 since there's no preamp out. Shiit Audio has some fairly inexpensive tube hybrid headphone amps with pre-outs that would probably work better.
Forgive my ignorance but what type of connectors are this on your speaker wires?
They're just banana plug connectors. For vintage gear, I use bare wire that's been "tinned" with solder.
Would this work with Tannoys that have a 88db sensitivity rating?
It works pretty well with my 85db KEF LS50s, so I imagine it would be fine. Just don't expect it to get really loud.
I owned these amp since 4 month and share to all of you whose have plan to rolling tube that dont waste money to change pre tube to russian tube, replace 6550 or kt66 88 the same situation cause of this amp designed to use EL34. Both Chinese 6n2j and el34 stock tobe are good. Only one tube you need to replace its voltage tube, i recomment use gz3r or 5u4g from USA. For anybody need more bass, change both interstage cap Philip 0.22 to Mondorf 0.47mf will satisfy your target.
Hi, and thanks for VERY interesting reflections to, and recommendations for , the A10!
I own the same amp since 6 weeks, and love it. I would like less forward upper mids
and a little fuller bass when listening to some recordings, so your tip for changing interstage resistors from Phillips 0.22 to Mundorf 0.47 is exceptionally interesting to me.
I must doublecheck with you though, that you mean 0.47 mikro Fahrad, NOT 0.47 milli Fahrad ?
Here in Sweden mF is short for milli Fahrad, and uF is for mikro Fahrad. The stock Phillips are 0.22 uF
I fully agree to your conclusion that people planning to spend 100-200$ on tube rolling, could save that money instead.
Tube rolling does indeed change sound characteristics slightly, BUT only nuances, not the big leaps you may need to take to get rid of a too harsh or forward high frequency range.
I HAVE done extensive tube rolling, and it's fun, but costly, and changes are minor.
I guess your proposed changes in resistor values does a more profound change to the A10.
Another means is to buy a Shiit Audio LOKI external 4 band equalizer, which is very good and rather affordable. Best regards, Magnus, Gothenburg, Sweden
What difference does the upgrade to USA voltage tube , like 5U4G do ? Audible?
@@vespass225 Thanks for your information. There are 02 interchange stock cap 0.22uf named c102 and c202 on schematic, you can change to 0.47uf the sound will fuller and more bass. Another solution, you can change resistor R103 R203 from metal res to composite res, the sound characteristics also change. Its cost will very cheap but imazing.:)))
@@tranhuynhgiao2337 Hi again, and thanks for confirming C102 & C202 swap from 0.22uF to Mundorf 0.47 uF.
Mundorf have several lines of capacitors, like "Audio Capacitors MCap® EVO" , "Audio Capacitors MCap® Classic" and "Audio Capacitors ECap", each with several different "flavours" and price ranges. Which specific did you try and have experience of?
Also thanks for additional tip on resistors R103 and R203. Those composite resistors, do you have any specific brand in mind, liike "Mundorf" , and do they have any power rating to consider, like maybe "2W" or "5W" or similar ?
Thx and greetings from a snowy , pandemic Gothenburg, Sweden
@@vespass225 I have tried Mundorf M cap evo capacitor for 9 USD / pc in Vietnam. Overall I think they are good enough for the all user. Regarding carbon resistors, there are some famous brands for accurate and warm sound: AB of America (A bit difficult to find in Vietnam, my country), Kiwame, TDK, Takman are all good, you can buy some values (75K 100K 150K its cost 0.9 USD / pc) to see the difference. You can choose 1w 2w or 5w resistors all of which is fine.
I have played with many components in this amp, you can try and need any assistance we will discussing together.
Greetings from Hanoi, Vietnam
Thanks for your video great work. I now have one of these and love it. Try these Albums from Tidal if possible (MQA) Blue Moon / Dean Martin 'Dream with Dean' 1964 (Amazing) and Leonard Cohen 'Ten New Songs' / My Secret Life (Also amazing).
Is it high current?
...uhhhhh.... China High Fi Audio ....they have a choice of 100vac, 110vac, 115vac and 120vac...???.... what do you pick for USA use????
I would choose the 120vac here in the US. The voltage is your house is probably even a little higher than that, but the 120 will work fine.
Would have been nice to hear it
What could you possible hear through a UA-cam video?
@@EliasTheHunter it gives you an idea even if not perfect
hq72hotmale I suppose it might give you a hint. I’ve never been able to get any detail like that myself through a video.
I hope you get a chance to check one out in real life! I’m building a Nelson Pass design soon: his amp camp kit.
hehe. What is it with this amp? It has received 3 reviews this year. I have Reisong/Boyuu's 300B and 2a3 amps. Both are just a tiny bit better than my First Watt SIT3 which I just sold. I just DO NOT LIKE SS anymore. These are my studio amps, not my 'real' amps, but hey. If i had never purchased a First Watt amp, and had it sitting next to a Reisong amp, for the cost....Reisong wins hands down. Oh....ONLY after tube and cap changes. I put Dueland caps in mine and some fantastic tubes. Hashimoto's prices have gone up due to the virus, if not, I would put some Hashimoto output trans. in both of these amps (but these transformers are more than the amp itself) :D. My others already have full Hashi stock :D
Oh, if you get flea watt amps any time soon, Omega speakers are great. Getting a very HI-FI quality sound with my Triod Lab and Finale gear with Omegas. If your tube amp is on the newer sound (bright/lean) don't do the Omegas.
What tubes did you put in the Reisongs?
@@ipensword My Reisong 2a3 has been collecting dust since covid started (currently in mid-upgrade non-working status) but from memory I have Shuguang 2a3 tubes, Northern Electric 6SL7 tubes and a JJ rectifier. My 300b currently has Shuguang 300BS tubes, Gold Lion 6v6 tubes, and a Electro Harmonix preamp tube (which is made by Gold Lion I believe). I never put in modern rectifier tubes (many have blown my amps fuses) aside from JJs and top tier PSvane tubes. My Triode lab amps both have PSvane rectifiers which are simply the best for my amps anyway. From what I understand, stay away from the rectifier tubes made by The Tube Store, due to multiple returns and failures -all without great sound to begin with.
@@vvcv__00 This is very helpful information, R M! Your 300b sounds like a sweet setup. It is good to know about the modern rectifier tubes. I had not heard that before and will stay away from them. Gold Lions are available for the A10, so I will look into them as well. Thanks for sharing your experience with tubes. Cheers.
@@ipensword You're welcome! I do feel that I left out some 'opinions' of mine regarding my tubes of choice. I feel you may experience the same results since we are using amps from the same builder. So, when I want a warmer and full/round tone I reach for the Gold Lion tubes, especially the driver Gold Lion tubes. If I use Gold Lion output tubes, I almost always use a driver tube like Tung-Sol 6SN7 tubes -which are more neutral to me. On the other hand, when i am craving a neutral sound, I will pop in Shuguang output tubes. By-no-means does this imply using Gold Lions as output or driver tubes make it so warm as to kill detail and richness and air. Violins still very much sound like violins not violas. Maybe this will help:
1. Warmest sound: Gold Lions in both driver and output positions (for getting laid sound) :D!
2. Warm sound: Output = Shuguang / Driver = Gold Lion
3. A nice touch of warmth but leaning towards neutral: Gold Lion = Output / Driver = Shuguang
4. Neutral: Shuguang = Output / Tung-Sol (for my amps) = Drivers.
5. I don't care much for the lively, quick and lean 'brighter' sound.
Hope this helps clarify more detailed aspects to my tube choices.
Happy tube hunting/rolling!
@@vvcv__00 How does Reisong A12 sound in stock form?
does this amp have a preamp in it as well?..so can i set it up as turntable to this to speakers?...and keep everything analog?
You'll need a phono pre-amp like the Schiit Magni to use a turntable, but speakers can be connected directly to this integrated amp.
What valves does it use
Voltage tubes: 6N2 × 2, Power tubes: SHUGUANG EL34-B x 2, Rectifier tube: 5Z4P ×1
@@nadiraudio well el34 you might be better off with kt77s preferred Choice for musicians, you can get solid-state rectifiers that come in a tube, that will give you a stronger bass might be worth swapping that out as well.
I have a Pioneer SA 8500II amplifier. Could I use the A10 with this? I'm a newbie to this tube gear stuff.
The a10 is an integrated tube amp without a pre in or out, so unfortunately wouldn't work with another amp. Schiit Audio makes some good tube hybrid preamps like the Saga + , though, which might be a good starting point to get into tubes.
@@nadiraudio Thank you
IT'S NOT ALL GOOD.
I have to chime in on the A10. I bought one ( $575 canadian), delivered from Amazon / March '23) after seeing several reviews - all pretty positive. My first impressions were NOT good. I found the pros to be 1) its build quality and design and 2) a midrange that has a nice immediacy and almost physical presence like you could scoop up the voice in a butterfly net. It was a new and enjoyable presentation of sound. I planned on using my DAC with it, so put it inline for my assessment.
BUT the cons were many. The lower midrange rise in the unit's voicing is simply too much. It clouds and blurs most elements in this range neutralizing its pro of midrange texture and presence. It's like bad food on a pretty plate. Yes, speakers play an obvious role ( I have M.A. Bronze 7's) but the highs I used to enjoy were rolled off so badly that I questioned if I had blown my tweeters somehow. Occasionally a little sheen would poke through but it felt restrained.
I found the bass embarrassing. Loose, sloppy, some notes resolved and others vanished. It felt incredibly incompetent in this region. Once in a while it was interesting depending on the source but as for THIS bass being THE bass I wanted to live with til I die... not a chance. It had NONE of the grip or punch or even consistency of a solid state.
THE GOOD NEWS....
The A10 makes a GREAT POWER AMP. It would be ideal if the preamp section could be bypassed but I simply run it full open and use the preamp for control.
So I use a DAC between my CD player and AMC amp. The AMC has wonderfully clean and musical tone controls and shows little difference in the tone-bypass mode in terms of cleanliness. I listen most times around 85-90 db and have tone pots set at about 2 O'clock. This combination is STELLAR. I have the bass grip and tone sweetening (and input switching) from the AMC and the A10 adds back the tactile lead vocals and realistic timbre of the instruments. Detail, air, texture and all the performance subtleties are brought to life. There's no denying the effect of tube-related harmonics.
This set up really accents the PEOPLE and TALENT behind the music. Dynamics, tonal balance and realistic timbre are all there. So in the end I can't say the A10 is a great integrated amp. I think it has considerable deficiencies. I CAN say it can be a STELLAR power amp. 12 total watts or not... it's the closest thing to "musicians in the room" as I've experienced.
I think my only future HiFi purchases will be tubes, just to experiment with different sound signatures.
