I have p-p amps that sound very good, so I understand what you are saying about
push-pull low-mu triodes with about 10 dB of loop negative feedback. Same for your
idea about coupling transformers, I agree with you.On the other hand, simple amps using single ended triodes are a modern fad,
but might they be on to something too? The one thing they aren't good at is power
but I think some SET amps sound very good at low levels. What do you make of this?
What makes a good SET amp? What is the nature of their appeal?
