a simple question from a simple man- how MUCH clearly audible difference, is in the sound quality of an SET, versus any other class-A amp? what are those who use high-efficiency speakers in smallish rooms hearing in an SET that they can't get from other Class A designs?
Class A amplifiers
I was watching YouTube reviews on Hifi and one guy said if you like Class A amps you have to accept that every 3 or 4 years you have to send them in to get serviced Becasue the heat inevitably causes issues? Is this true? I have a friend with an older Maek Levinson Class A amp and he was looking to sell,it to me, and am just wondering if Class A amps are like a boat, always costing you more . Anyone?
