I saw it before in A07 MAX .The best neutral and musical opamp for the MAX is for me the JRC 5532DD from japan.
Thx - In the Cyber Monday promotion, I got it for $74.50 with a 48V/5A power supply, but the delivery is only around December 20th... plenty of time for better/worse/the same speculationsI don’t know why would you take my advice on this, but if you do and if you have got 100$ spare then just get A07 Max.
Amazon will have good return period safety, but I highly doubt one would return this amplifier unless get a really broken piece.

The source for A08 PRO in my case is the Aiyima T8 preamplifier with a GE5760 Triple Mica lamp, which gives a pretty nice midrange and unobtrusive low frequencies.I also should have added that if you tend to prefer a slightly more bass and upper-mid presentation then ZA3 is fantastic amplifier.
For a more perceived neutral presentation, A07 Max.
You'll see a range of opinions represented here. Most experienced EE folks say to leave the stock 5532s alone. I swapped for 4562s in my Aiyima A04 and A07 amps just to be sure the parts were genuine (Fosi has shown good documentation for the V3 that they are using real 5532s). Some op-amps if not correct for the amp circuit can cause oscillation and bad things can happen. My advice is that if you do try a swap, use a test setup with low cost/sacrificial quality speakers first.Has anyone properly measured whether changing the op-amps does anything? I see a lot of people swear by it but it smells a lot like typical audiophool bs to me.
@Joe Smith You can use the flashlight to see these through holes in the right side(May try again eventually as I'm curious if I have the 50v large caps in there or the 63v ones.)
I have change several times change opamps like 50 times in Aiyima 07, Aiyima07 Pro and Fosi V3, they do sound different and make improvements in sound, since the are made for different voltage and applications, I have the Sparkos labs SS3602, Muses02, lme49860, lm4562, opa1692, opa2604, opa1656 ect. Never have a problem they have to be dual or mono to dual opamp and can only be place one way otherwise booomHas anyone properly measured whether changing the op-amps does anything?

I can only advice to replace it with same ones if you want to be double sure that opamps aren’t limiting anything.Has anyone properly measured whether changing the op-amps does anything? I see a lot of people swear by it but it smells a lot like typical audiophool bs to me.
You are going to get 63v, congrats.Thx - In the Cyber Monday promotion, I got it for $74.50 with a 48V/5A power supply, but the delivery is only around December 20th... plenty of time for better/worse/the same speculations![]()
Unless you did double blind tests or measurements I don't trust anecdotes like this. Too many variables, and our brains are easily tricked into hearing differences if it expects to hear differences.I have change several times change opamps like 50 times in Aiyima 07, Aiyima07 Pro and Fosi V3, they do sound different and make improvements in sound, since the are made for different voltage and applications, I have the Sparkos labs SS3602, Muses02, lme49860, lm4562, opa1692, opa2604, opa1656 ect.

You are right is just games that my mind play...but I am not the only one, this people are also Krazy https://www.head-fi.org/threads/the-opamp-thread.432749/Unless you did double blind tests or measurements I don't trust anecdotes like this.

A07 MAX~80,00 $Otrzymałem A07 MAX z zasilaczem 36v 6 A tuż przed Świętem Dziękczynienia i przetoczyłem wzmacniacze operacyjne do Sparko SS3602. SS3602 zapewnia ulepszoną scenę dźwiękową z lepszą rozdzielczością między dwoma kanałami. Mam też oryginalny A07 ze Sparko SS3602; Brzmi też niesamowicie. Jeśli przetoczysz wzmacniacze operacyjne na A07 MAX, uważaj na dwie diody LED z przodu przy przełączniku włączania/głośności, ponieważ mogą się źle ustawić i zerwać. Wymieniłem również z sześciokątnym na radiatorze, ponieważ inni powiedzieli, że dość łatwo się zdejmują.
I wish if I had experience with the opamp rolling thing, but somehow I find it funny every time I think that opamp costs twice as the amplifier.A07 MAX~80,00 $
2x Sparko SS3602 = ~160,00 $

~240,00 $
You are correct that the cost is expensive for the amp and the op-amps, but the outcome you get for audio clarity and sound stage presence is unbelievable. I will say that the small form factor for the amps is a plus for a garage or small office system which is what I use these two Aiyima A07 and A07 MAX for. I haven't heard a $240 amp put out that kind of sound and I do have a Yamaha RX-A3080 that doesn't sound as good as the two Aiyima A07s.A07 MAX~80,00 $
