I did say atmos so 4 speakers in my case, I didn't mention bed layerI.e. you need 5 of these amps.

Good point. The rules it out for me.Probably just fine.
Tried something similar, but didn’t feel safe to leave powered ON and hate to power on/off manually every time/day.
Power ON/OFF merged with vol. makes it difficult to put it back to same calibrated vol. settings.
A power amp (no vol., but a power switch not just mute function) of similar quality/specifications would make a great used case with avr pre-out.
Atmos is a superset of surround with the edition of height speakers. The 7 surround, 2 heights and the LFE channels are called the bed layer. On top of that you have the objects that can be positioned within the 2pi sphere.I did say atmos so 4 speakers in my case, I didn't mention bed layer
You REALLY like to "hear" yourself talk, dont you? You know VERY well that by ATMOS we always refer to the top speakers but I guess you love to be pedantic (Ted Mosby much?) for ZERO reason.Atmos is a superset of surround with the edition of height speakers. The 7 surround, 2 heights and the LFE channels are called the bed layer. On top of that you have the objects that can be positioned within the 2pi sphere.
Atmos playback requires each bed channel at minimum to have its own speaker. Otherwise, sounds on bed channels are created with phantom method, like the phantom centre speaker. If your setup doesn’t have side or rear speakers it is not possible to create phantoms of them. That is why anything less than 5.1.2 is a limited solution that is only acceptable if your listening environment is 1pi, I.e. you sit with your back to the wall.
I hope I was clear.
There are speakers that have high frequency impedance much higher than 8Ohm... The setup is very bright then...So, you are adjusting the "volume range" from your preamp or source, not the volume knob on the amp.
ADD off topic: I'm confused about the attention paid here to the Impedance dependence graph. It looks nasty because the steps are small, but can anyone really hear a +/- .5dB variance above 10K? Perhap we just feel better about our gear when we see straight lines?
?To all comparing the Fosi V3 to the Aiyima A07 , please pay attention to the max gain difference between them.
The Fosi V3 max gain is 20 and the A07 max gain is 40. This fact can explain the few dB advantage that the Fosi V3 has on the A07 with the THD+N results.
No other magic.
I have two 32v power supply from Aiyima and Fosi, I tried both on Fosi V3 and Fosi PSU sounds more clean to me.Hi folks.
I'm using an Aiyima A07, with the stock 32v PSU.
Just bought the Fosi V3, without the PSU, to use the one I already have on the Aiyima.
I listen in near field, low volume level, so I don't need too much power.
Could I get a better sound quality with another PSU or would be the same as the Aiyima 32v I already have?
Thanks!

I had not considered how Gain and THD=N are related. After Googling, I see gain is a factor but I am still confused as to why.......By the way all my A07 measured THD+N are better than the one Amir measured. They all come aground 87dB.
As I see it the biggest Fosi V3 advantage on the A07 is the heat dissipation capability.
Sorry, I didn't get it.Oh c'mon...
One power supply seemingly cleaner than another seems very subjectiveSorry, I didn't get it.

Amir measures THD+N at 5w. Intuitively that specification would not change regardless of what gain the amp employs internally to reach that 5w. How does this work?
I agree that the THD+N measurements on the Aiyima A07 Pro and V3 would be indistinguishable in use. I would argue that heat dissipation difference would matter primarily on a test bench, a tiny minority of owners will tax the dynamic output of either one.
More likely the A07 Pro's channel imbalance and lack of center detent tone controls could be audible in blind tests.
But 98% of owners do not do blind tests. The audiophile friendly design choices Fosi made in the V3 will assure that it produces more endorphins than similarly priced competitors in ASR readers.
I'd rather have the slightly lower gain to achieve higher THD+N. Also, I don't think you can achieve the SINAD difference between Aiyima A7 (83) and Fosi V3 (88) by simply lowering the gain.I meant ratio not in dB. So in dB it will be 26dB for the Fosi V3 and 32dB for the A07.
Amir measured around 26dB for the Fosi V3 and 29dB for the A07.I have few A07, and they all measured gain are 32dB.
Still there are few dB gain difference between them that can explain the few dB THD+N difference.
By the way all my A07 measured THD+N are better than the one Amir measured. They all come aground 87dB.

I thought that was a pre-requisite or disclaimer!But 98% of owners do not do blind tests. The audiophile friendly design choices Fosi made in the V3 will assure that it produces more endorphins than similarly priced competitors in ASR readers.
I think it actually feasible if you want to mod the A07 by replacing the 20K feedback resistor on the A07 input op-amp to 10K.I'd rather have the slightly lower gain to achieve higher THD+N. Also, I don't think you can achieve the SINAD difference between Aiyima A7 (83) and Fosi V3 (88) by simply lowering the gain.
