Apologies I meant to post my comments on your BRZHIFI E600 video DOH!

@@BlazSvetlic soon, it was waiting in line for fat too long!

@@tom123 it's in +/-2V range as far as I remember from playing with it

@@k4syx Nice! That range of adjustability would work for me. I am looking for an LPS of reasonable quality and price, which would also allow me to fine tune the output voltage for my specific needs. Based on your experience and reviews of other LPSs, within the $100-$200 price range, would you recommend this LPS over others?

@@johnwicks6187 wow sorry no idea :) These are either fakes or shoddy originals. I have no way of doing elements analysis on it :D

@@helmut3356 No they don't, cat said she measured it with my laser meter and to her (and mine) surprise it was just 35C on the cap side facing transistors. Perfectly safe!

@@k4syx Thx

@@liangsek8243 yes it's a very simple, uncomplicated and cheap (or rather value) build

@@dugenounonplie8162 wow I'm pretty sure I wasn't looking into your package :) I don't have that kind of super powers:) Jokes aside, probably customs. It doesn't come with any manual so that's normal, but mine (bought from the shop I linked in the description) was very well protected

@@onnonugteren2935 my comparison is not ready yet - no time :( But I'm thinking and planning for mods and I have some things figured out - at least in my head -already (these won't be the first headphones I modify)

@@k4syx Yes modification. I am guessing that it's not worth it. ...So I am highly curious about your experience. Not worth because I now have come to the end in my believes that these headphones RE9 are really great AFTER a long about two weeks of burning in time, one even four weeks. And other headphones differs more than with a small upgrade at costs of sound also here with the RE9. That's why I am interested in your comparison with the Anando Nano's, a very different headphone. Between the lines I believe that people who did the modifications on the RE9 did not give a good burning in time and time to enjoy the result: that specific thing, mixture of sound end result. So if you leave one original and 'mod' one than you are fair to the RE9 and mods and other types. About headphone cables...: that's another story here with the headphones, I do think this is something I would like to know how much difference it makes to change them for 'better' ones if at all. The original cables are short and good, so will it really matter that much as with speaker cables? What do you think and what do you think about my thoughts here? Greetings again. 🙂 And yes for many hours I really enjoyed the end result with these RE9> so specail effects and sound: never heard before but never did try also: granted. Still superb sound with my Chord Mojo combined. 🙂 ... Ah and the differences are now very small between the two I have. So that tells a lot good points for the RE9 the second one just needs some more burning time to my little experiment.

@@stephanloper5740 for this one I would go for either JC2 or Cary from the ones I've reviewed. With slight bias towards JC2 for it's clarity and precision, to maintain that raw and wild feeling

@@Gary_J OPA828 for I/V and Akliams for LPF. Staccatos went to BTL mono set :)

@k4syx I'm new to this so I'm assuming Texas Instruments OPA828 chip soldered onto a Dip8 holder? Which model of Akilam, would they need the flexible silver extensions you reviewed recently and still fit into the chassis without having to cut a hole through the top? It would be great if you can do a quick video about it and point out what changes you heard in the sound quality. Thanks

@@Gary_J yes your assumptions are correct and it is Akliam LC5 - it fits without any mods or additional stuff

@k4syx sorry to bother you again. OPA828 is available as single and dual, which one do i buy? LC5 is only available as dual, I'm I correct? Also the ops amps would impact sound on both xlr and rca outputs? Thanks

@@maxrider2887 I haven't got the time to play with bias (yet, as I'd like to do a video on that as it's easy) so can't answer that (yet) :(

@@k4syx waiting

@@maxrider2887 I'll do a video on that so I'll try to get measurements there (fair warning: may be a while because of lineup of amps waiting for review)

@@onnonugteren2935 24/7 training!

@@FDKAUSW for D5PRO specifically, go for Cary. And plan on getting better tubes, stock psvanes are very good, but you can get even better 12au7 stuff

@@k4syx witch ECC82 are bether (LINK) and witch Capa's (LINK) too? Thx.

@@FDKAUSW these tubes (12au7-s) a.aliexpress.com/_Eu2eGad I'm getting Jantzen Standard and Superior caps locally so no link :(

@@k4syxon ‘Choice Day’ sale Oct 1st (maaaay be US only)

@@raynerstuelgalid yes, quite cheap, some area for cheap improvement :)

@@raynerstuelgalid yes I absolutely love the color and how it matches the gold front. I know, I know, I have cheap taste, I like shiny things and some bling :D

@@rvaillant check my other video reviews, I'd say that this stuff is my specialty by now :D

@@Uraim kudos for loving and caring for your equipment!

@@sginfdfw Thanks! I got one of the Alephs on my list, I think it was 5, but recently I've f the viewers warned be about Aleph 3. This is obviously a different amp but I will be careful, I'll do some research before getting one

@@k4syx I too have read on many threads that the ALEPH 3 was not good. I wish there was someway of accelerating the burn-in process. It takes sooo long

@@sginfdfw yes it takes ages, that's why I try to do fists look videos, because then it's like two weeks (at least) before the full review But it's worth it, definetely, as I've learned over the years. Better to do it once at the begging and leave it behind enjoying the music later

@@michaelbooth6007 I think it's in the video description. This time I haven't even tried the electrostats, but the rest was the same as usual: Martin Logan Motion 35XTi and 15, Dali Ikon and Opticon

He has a) Dali ikon 1 mk2 and b) Dali Opticon 1 speakers both of which are 86db sensitivity, as well as c) Martin Logan Motion 15i and d) 35XTi speakers which are 92db sensitive. Now he can tell us most easily which ones were used and he can spend his time buying more stuff!

@@OlympicBruce yes thank you and both ikons and opticons have modified crossovers (better caps) and they are significantly clearer and more transparent than stock ones

@@k4syx hey, I also thought I saw you modified the crossover of your Ascents (which you didn’t use in this test as they need more power to sing). What did you modify there? Just Caps . (Maybe I saw a vid of your crossover but w no description). Thx ☺️

@@OlympicBruce yes exactly :D Just the crossover, just the caps so far, I want to do resistors too but I need to find some that can be mounted using screws like stock ones. Haven't seen anything like that yet, but I wasn't looking to hard, delaying that to some lazy autumn or winter afternoon :)

@@oldboy4150 yes I'll do that once I'll get back (I need time!) to serious listening sessions for cables. I want to compare totl fakes.

@@k4syx That's great ! THX.

@@azmansalleh2866 I'm gonna do this and do a video on that, soon. What I'm wondering about is if I should also cut these long PCB tracks, so they stop acting like antennas. It would be reasonable thing to do but I'm reluctant to cut anything permanently

@@AlanKelly-fe4yk Yes, that's correct. Here where I reside 36.6 is considered sweet spot, but 37 is perfectly fine too, and actually proper temp for children (they tend to run a bit hotter than grownups ;) )

@@k4syx What temperature does the reviewer state that he measures on the capacitor at 8:55 minutes? I heard it as 55­°C, am I mistaken?

​It sounded a bit clumsy, but apparently he meant 35°C, because he goes on to explain that if he had held it in his hand, it would have been warmer.@@AlanKelly-fe4yk

@@AlanKelly-fe4yk nope it was 35C, I may not always speak with my best, clearest English when I'm a bit tired :D Sorry about that. :)

@@wim1983 that's possible, I have stereo mics in my phone camera and I'm sitting behind tripod, but not always in the center. I'm moving around now and then. Good ears!

@@k4syx I see

no this is class A design. All sound can change with your adjustments. Go to original article from JL Hood and websites around this build and you will understand that adjusting power voltage and quiescent current you may have totally different sound! this amp especially changes the sound due to operational current.

@@yellow_noise3 class a can have push pull too

@@MasterofPlay7 I wouldn't go as far as to call them lean, but not fm300a sweet level definitely

@@yellow_noise3 yes I've read that too! Makes you wanna experiment with pots and voltage meter!

@@k4syx I'm surprised that with the price it holds up really well to something double the price like fm300a and in some aspects beat it

@@eugenefudge3685 none, pure DAC output to have it as simple as possible

@@raynerstuelgalid that's an interesting idea as you could move them outside to separate chassis too. I think just two transformers would do, I'd need to check if there's anything between power socket and transformer (not counting power switch) as I don't remember it now (but I don't think there was anything)

@@k4syx What's the rating for the existing trans?

@@raynerstuelgalid I don't remember if that's in the vid (should be if there was a sticker with specs), I'd have to open it and check

Hi! Some but not all pure tube amps will give us those dopamine shots. But thats not tube sound that every single tube amp will have, just the best. In this case I was talking about this smoothness and delicacy tubes usually provide, so tube like sound - but not to the Cayin level. But with better 3d here :)

@@k4syx Ahaa... ok :)

@@majtextwriter1794 kinda hard to explain with words only (at least to me). I have this idea to get these maybe to some local diyaudio gathering for guys to listen to them. Just an idea at this stage!

@@k4syx I know. Good idea. I also performed some blind A-B tests with some my audio friends or even by my self.

@@majtextwriter1794 these are quite easy if you know your setup by heart and you've chosen tracks with specific passages that you've heard a thousand times. And I'm a cheater using electrostats, there's that too :D

Two weeks usually, sometimes longer, if I dont have the time for the review I'll just leave the amp playing. Yes it does change things, especially during first half of first week. Some devices will change more, some less. As I try to review them in their best possible state (and check for reliability) I try to keep this 2 weeks time as bare minimum.

I'm not sure I'm a "long term burn in" believer, or at least I haven't heard a difference yet in my lifetime. I do have the A1 clone and I think it does sound a little harsh in treble until it's warmed up (10 minutes max) but I haven't noticed any changes day-to-day, or week-to-week. It sounds beautiful every time after a few minutes to warm up, I can't stop listening to it and so glad I found this channel!

@@Sammelwuetiger I think depends on the speakers ..may be your speakers are high sensitive ones .. in a system I like, sansui x0x0 series .. the 5050 is better among 8080 .. 6060, 5050..5050 with a lower power rating ..another reason may be the capacitors inside some amp are dry .. but the best one will stay at the audio rack right? Haha . Our ears are picky !

I am surprised no one ever mentions Bi-Amping with these. You can enjoy the sweet class A sound on the mid-high range and put a powerful class D or AB amp for the bass.

Dude, I'm using 2x5W tube amplifier i built myself with cheap floor standing speakers with only 86db sensitivity. Still plenty loud for home listening.

Granted it won't run a nightclub but 15w into a decent speaker with sensitivity of 86db+ will still get to uncomfortable listening levels for the average listener at home (assuming they are not already suffering from hearing loss).

for reasonable listetning levels, with bookshelf speakers its perfectly fine

@@k4syx The 331 is 12 watts and has no problem driving my bookshelves.

@@D1N02 yes for efficient bookshelves this is probably excellent choice as this is so small it will be ok as real desktop amp

Burmester got me by surprise, its raw. 1969 is delicate, smooth and airy, excellent for female vocals. You do not want these served raw, and you do not necessarily want to have your hard rock smooth and delicate :D

Yes it is! I have it lined up

I kinda felt it coming :)

Had a mf a1 before .. not enough to drive 3/5a or may not be able to full utilize 3/5a.

Ps MFA1000 worked well with 3/5a and audioquest midnight blue but beautiful midrange but prepare that bass and soundstage may not be the best ..anyway 3/5a is a challenge for the amps .. if I were you I would try the d5pro or some good tubes( may be a killer midrange that may be the reason a lot of tube amps demonstration using 3/5a before ..)

How much is your 3/5a.? Good sound ?

With 15 Ohms I wouldnt gamble here :)

These one was apparently suspicious enough to get catray :D

@@k4syx i think the cat likes it, it's cat approved :D

@@k4syx 😂

@@MasterofPlay7 looks like it:) That was the first one that got so much attention, she usually sniffs them during burn in but with little to no interest. This time she saw me doing something with it so she just HAD to check what's up:)

Oh no .. I bought my jc2 clone from them .. the others were out .. I owned MFa1 before ..everybody said it is the best entry amp.. warm sound and etc.. but it was ok too .. well might be the speaker just Mission cheap cheap speakers .. just normal otc interconnection rca cable and speaker wire and Philips 850 mark 2 or a DVD player .. might not be able to full utilize the amp .... Lost $30 and sold it

@@richardlui8914 The Missions were bottle neck here. This shop is ok, the amp may be a dud, thats I always try to do as much reearch on any given device I can, before the order

I know aesthetic are a subjective thing but VU meters are always nice to have! Cases look boring without them

Yes, these are nice for aesthetic purposes but I wouldnt even try to read anything there, just look at these fancy dancing needles :)

You make a good points, for fuse I'm using external fused power strip (I may replace power socket with something that has fuse integrated in time). I havent thought much about other innards as the ripple was quite low.

I hate that question! Why one? Why choose? :D I honestly cant tell you anything because I love all of them so far, for different reasons and for different music genres (sometimes) :D

Havent heard that one (yet). I think its on my list, build with silver case and two knobs that are not exaclty symmetrically placed and blackstripe.
