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?

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?

My two cents, flip the questions around. Focus on yourself.

What is IT that you get from .... ?

If properly ventilated, class A amplifiers will live a very long and healthy life. Mo ventilation, Mo better.

That is a giant load of dog doo.  I have 4 class A amps in house. Two First Watt amps, and a pair of Monarchy Audio SM70mkII's (I run these as mono blocks)  The FW J2 is the newest,built in 2017. I am the second owner of FW F5,that I've had for at least 6 years. Not sure when Mr.Pass built that one. The Monarchy's are at least 10-12 years old. The pair I have I believe are one of the first MKII's that were built. Not a hiccup out of any of these amps. Ever.  Ya gotta love YouTube.
