I dunno about you guys but I had a hell of a time removing noise EMI in my CSX1 that I ended up building separate chassis for the power supply. Perhaps the Nuvotec made, potted toroidals gave off some weirdly EMI, the noise was easily measured between covers on or off: Post #5 below:

Todays plan is that I'll be fitting Cinemag autoformers, using SMT caps on the back of the bords and a GOSS banded traffo mounted as far away as possible from the boards.
What I'd really love would be a Vishay pltu SMT version with the upper (and maybe also lower) layer of the board as a ground plane, earthed via the mtg posts. All the resistors and caps on the back
Might there be any possible benefit in mtg the transistors on the back with their heads pressed against the heatsink - also with a dab of thermal grease?

Very good answerwhen OCD is in question, Sky is the limit
so, just set eyes on your own Sky, I already have mine
Boards and parts have arrived
I wonder if anyone would have the time to mark the signal path on the circuit diagram? I'm a little confused by it. M2 was much more obvious.
Huge thanks to ZM
forgot to say - if you still need signal path sketch, just say
amp is extraordinary simple, you just need to recognize function blocks
maybe this could help. at least regarding OS arrangement ( biasing); practically first page of thread: https://www.diyaudio.com/community/threads/sissysit-r-3.371272/

question is not stupid ...... only rationale behind it can be
that's practically sole ( serious) cap in signal path .... but it's sonic footprint ( if made as I made it - Silmic+MKC bypass) is much lesser than you think
I have a version of amp (in fact - all of these autoformer based) with current mirror biasing (same as in Babelfish XA252) which allows direct couplin all the way from input to output, but this si not time to pursue that
maybe in future, when I'm done with all amps (Plethora series) waiting in line to be published
