The TPA3255 at 32v is able to provide a "clean" 1% THD + N output power of 110W per channel. That means 220W total. P=V*I therefore...

Yep. Eg, here and here. And here. :)

Yes, the stock power supply is way more than enough. I have an Aiyima A04 and I'm using a 20V 4A laptop charger (more than enough). I...

I want you to look at the TPA3255 datasheet at figure 8: This shows you how much power the amplifier can output at specific input...

I'd bet he does not need more than 5W/ch (being generous). Really, what is all that need for "more power"? If people measure the voltage...

With that sensivity you will likely not need more than 20wpc, so any adapter will be fine. Unless you go with very loud music (Which can...

i replaced inductors with coilcraft oem, some wima and nichicon capacitor. I using muse02 but ordering some opamp to try Using 2nd...

As promised. These are some pictures of my modded Aiyima A04: OPA1656 on adapter with multiple supply bypasses. ELNA Silmic II Coupling...

Definitely looking forward to see pictures of your mods. I can share mine as well.

Just got some parts in and changed the volume pot with an ALPS 50k Logarithmic, if you do anything to the A07, I totally recommend doing...

Feeding with a higher input voltage allows it to have bigger swings on the output, therefore it allows you have more output power until...

A bit off topic, but … when I played with tpa3116 cards one of the best mods where to switch the capacitors to bigger ones - I bought...

With my A07 i was using a 24v 4amp supply since changed to a 48v 12.5amp being fed by 240v mains (live neutral earth all connected), The...

Again. Have you measured how much power you use during your listening sessions?. People who listen at 80db need less than a watt per...

I'm not sure if people understand how much power they really need. Please measure average or max voltage at the speaker outputs...
