I see on V3 warmer sound than on ZA3. I think if I need only amplifier without other features I prefer V3.

But on site was 7 days, also see its starts

As we can see Fosi delayed sales of ZA3.

Guys, I don't understand why you need a 48V PSU, Who listens to music with 100W power per channel? 32V 5A is enough. Who says the difference in sound between 32V and 48V I don't hear it.I have Aiyima 07 MAX also, the sound first looks more detailed in highs, but it's far from neutral and...

Yes. Fosi use better quality potentiometers.

Don`t tell me that thing, now have 2 pcs Aiyima and it's the same little problem. Fosi also now I have 2 pcs no problem with both, I think Aiyima have some part potentiometers with problems

At a low volume level between 9-10 o`clock it has, I put it on 12 always and everything is fine. I have now 2 pcs Aiyima and it's the same little problem.

Temporarily have Fosi V3 with stock OP amps, he sounds a little warmer than 07 Max, also when putting the volume knob on at 10 o`clock aiyima has a disbalance in channels Fosi doesn't have it, also when turning off the amplifier knob on Fosi click differently than aiyima I think is 100%...

I don't know how people's likes the unnatural sound of sparkos OP amps, it's most overpriced amps with terrible sound .Most relevant OP amps OPA 1656 and 2604,and price is very cheap for good sound. But I say many times, the MAX is the first amplifier what I can listening with stock OP amps.

я talking about it/In my amplifier i dont have that problem.

I think it`s a problem with the potentiometer. Now I have A07 Pro in volume button at 10 o`clock I also hear the difference in volume in the right and left channels. I set the volume button at 12 o`clock and used the preamp in DAC and had no problem with imbalanced channels. The amplifier gives...

@Joe Smith You can use the flashlight to see these through holes in the right side

I saw it before in A07 MAX .

@guddu Why Fosi do not sell ZA3 on Ali? I also can't see it on the official page.

But aiyima sound better.

Sorry guys, I don't want to say bad things about it, maybe the measurement was taken at a loud volume level. Why do we see that difference in distortion, It is a mystery.

Yes. This topic is for MAX and I say about it.

Strange. In the RMS measures aiyima have bad results.
