Very nice components selection especially capacitors. My only "remark" is that I will place a metal sheet shield between the PS and the amplifier (somewhere side by side to the 2 red capacitors 5:40 ) but again it is a matter of experimentation. I hope it is a diy amplifier (so all the credits to you)
I selected the parts and built it myself. I paid particular attention to heat and long-term reliability. The mil-spec foil resistors and silver-cased wet tantalum capacitors are of the highest quality, and are of the grade that can be used in aerospace and nuclear plants. The solder is Nassau and Kester 44 silver additive. This is a boutique amplifier with point-to-point wiring.
