I installed quite a lot of advanced industrial systems in the EU, USA and Japan. US and especially Japanese mains grid have always been...

Same here, and in many EU countries. 400V is between 2 phases, 230V between 1 phase and neutral.

230V single phase, 3x400V for power requiring appliances.

Hopefully we have 230V mains.

How do you invert phase in the other channel? In the amplifier or in the source/software?

Balanced output from the source DAC was used. OUT+ to Lchan input, OUT- to Rchan input. It is just for fun, no serious project planned.

Another amp that does not meet its output power specs. So usual, nowadays. And not many seem to care.

Direct comparison of THD vs. output voltage for basic single-ended and balanced configurations. Distortion reduction is stunning, as a...

Parasound Halo JC-1, to drive low impedances. Or my PA4 :).

Going balanced (1 board needed per channel) decreases distortion considerably, like 100x, 40dB down.

If I had to spend one word, it would be - boring.

You know what - arguing from technical standpoint with laymen enthusiasts might only bring you to the lunatic asylum. To me, there are...

This is on my workbench :).

Sorry but it is highly unlikely, as I do not give away gerber files, unless it is declared as a free open project. On another note...
