The A07 Max with a 48V power supply gets hot, not because of actual output power consumption, it's because of the voltage regulators...

The RCA negative wires and power ground are connected. Try using different power supplies for each amp. You are having a ground loop.

Not sure if I understand correctly. But one way to find out is swapping RCA cables to see if the noise follows the rca cable, or also...

On the Aiyima A07 Max thread we recently had a conversation regarding those capacitors. It turned out that a ceramic ones (instead of...

On both dual inductors? What is your power consumption?. 30degC above ambient temp do not seem excessive. Those inductors have aprox...

Hi Daniel. I updated my reply to add a link to a passive adapter which is cheaper than DSP and works for your particular need. A DSP is...

Greetings. I understand what you are planning to achieve. But this is not the "mono" you are looking for. The Aiyima A07 MAX (the same...

Hey, MCH. Me neither, but it gives me peace of mind knowing that better components are used. If it sounds good that's all I need. But we...

Aiyima, It may not seem a lot but those few 0.00xx% mean almost 2dB lower THD+N (according to Trung's measurements) and that's a great...

Very nice, thank you. Any improvement is welcome.

I replaced the capacitors with regular x7r 100v capacitors, nothing special This is the measurement result before and after my changes...

Hello Trung. I could not wait until the weekend, haha. So, I just opened the amp and measured continuity on all those caps, and...... I...

Okay, you can be skeptical. It will be easy to check on the actual board, but I give you this picture, you can see the decoupling...

I'm sorry to differ, please reconsider. On all TPA3255 design there are 4 big ceramic capacitors next to the chip. These are the...
