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?

I’ve recently come a long way on my push-pull, class A, SS, tube, hybrid, SET, SIT amplifier journey.  IMHO, my SET implementation (dual Coincident 845 Turbo’s -28 watt and 94db efficient speakers) brought me closer to acoustic music than any other implementation (of approximately 25 different amp combinations- Bedini, BEL, Threshold, Muse, ARC, Moscode, Counterpoint, etc.). Terms like organic and realistic applied.  The realism of an acoustic guitar was breathtaking. However, the tradeoff was weaker dynamics- somewhat thin sounding on large dynamic swings of rock and orchestral music.  In the end, I settled on an Firstwatt SIT-3.  Nearly as good as the Coincident SET in realism, but with a far superior coherent presentation of the entire audio spectrum. I can say I’m temporarily satisfied.
