This amp bears no resemblance to earlier Counterpoint amps being a completely different circuit design. It has only a pair of 6sl7s for input and a separate toroidal choke regulated supply for the tubes. No funky tube matching issues like the old SA20. It uses matched bipolar output transistors not Mosfets with no resistors. All the parts in it are custom including the wiring and over 50 TX 2575s in the signal path and a giant custom Plitron power transformer for the output stage.Agree. Would not advise 80v caps on a 75 volt PS rail - using 100v on its twin. The muting relays minimize current surge on turn on. These particular PS caps have been in use for 15 years with no issues.
Sounds better than nice......
