Default TRY THIS WAY FOR NATURAL SOUND

You need a DAC with balanced output
two little transformer like 50VA
and use secondary as primary (raise 1to 20)
and then two amplifier with gain ONE
(mine is a car amplifier sony XM4040)

volume is on your desk by USB

Default New PCB design

to better secure the benefits of complementarity
a good method is to select pairs (hFE)
and couple them thermally

Hi Stee, I can not comment on any of the circuitry, since I am no expert.
But one thing I know for sure, Transformer is "not" a wire with gain...
Transformer might be a lots of wire mostly, but it does not behave like wire with gain.
Google core saturation and hysteresis...you will see things can get pretty compicated with transformers.

You're right. Transformers are TWO wires with gain.

I thought this might have something to do with listening to hifi outside and in the nude...
