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!

Many amplifiers that we have repaired just were not that well designed and or did not have the proper design to remove the heat. Think Counterpoint - mosfets back then were not that great and they were covered with a cap. Against all understanding of how to remove the heat so they failed. Also lasing long and producing good sound have nothing to do with each other.

While it was a common practice and there for a reason, I have also seen many covers with holes so the heat does not get trapped. While it may not be the single cause of failure, IMO and from repairing about 50 Counterpoint power amplifiers, I would suggest that the covers while providing a benefit, are not optimal for heat dissipation. YMMV Happy Listening.
