I think they are about the same. Alot depends on how hot the amplifier runs I think. I have heard that really hot amps cook the capacitors and make them age faster.
amplifier longevity
Is there any difference in longevity and or reliability between valve amps and solid state amps?
I thought that perhaps design differences between ss and tube amps might be a factor here.
Specifically I am considering the valve amps by Rogue Audio vs. the solid state amps by Luxman, both great brands in my opinion.
Thanks!
