It's more like NTC's internal temp peak for 0,7 s at SSA soft start, on outside one can hardly notice a temp rise.

No I'm sorry I didn't try any stabilized power supply for front-end or output at SSA. I had my MonoLith amps with front-end stabilized and regulated but my later designs works fine with just regular general smoothing. I found a lot more sense in separate ciruit sections to have near perfect local DC voltages, currents, etc. I look to general power supply more like as a mains power, enabling low Z, the rest is on certain circuit points.

BTW I sold NC400 monoblocks to one class D fan and he said that they're better than NuForce's monoblocks.

I Don't like supplies with feedback loop, but i always found real improvements with simple ballast (zener at base) for the power stages, even if the previous ones where totally stabilized and regulated.
Why not try-it once, it is not complicated.

Hi Salas

It's nice to see the insight of such beautiful DIY audio session as you thoughtfully prepared it. All predominating factors were measured and evaluated to be sure that everything is electrically OK before starting the test. As expected TSSA (Sonny's version) proved to be competitive enough to play its important role in the presented system. For this thread I choosen four pics as I think they can be very appealing for someone potentially deciding which amp to build.

The MKP caps positions across the feedback electrolytics were tried out and soon abandoned for they introduced some brightness in that system, I may add.

try adding 1uF - 4.7uF with 0.2R in series instead - it sounds much better
