We need a formula with a number of parameters (including the price, and a few parameters that measure the SQ, and a few parameters more like the weight, the size and the power consumption of the amp, etc) to measure the overall benefit/performance of each amp. We may easily construct that formula if someone will carry out experiments and put the corresponding parameters into the formula. @jeffseight , does it look good to you?
@tweak1 I am sorry for that accident. Something similar happened with my Megaschino, but it was finally repaired (just 10 days ago). Now neither am I in an extreme hurry to repair my 5.5 watts SET amp (earlier the left channel EL34 tube of the amp was blown up and damaged the 50 v 470 capacitor which is just below the amp. The amp still worked but the left channel was a bit weaker. Finally, I decided to replace the capacitor. We touched just this small part of the amp, nothing else. Surprisingly, no sound coming out of either channel anymore. I have no idea what could happened. The amp has a blocking system, which now does not unblock).
