What is the expected lifespan of a quality solid state amplifier (Krell, Mark Levinson, Anthem, Bryton, Pass Labs)? Is their any maintenance that can be performed to extend the lifespan of one of these amps?
I listen with Audire equipment. A power supply capacitor failed in the Diffet preamp and was replaced. But the almost 50 year old Model 2 amplifier soldiers on without fail and sounds amazing.
