I could be wrong about this but I thought that class A amps were least efficient when not driven. If I'm wrong I'm sure you good souls will correct me. If the first premise is true, I would think that leaving a class a amp on all the time would needlesly shorten the life of the amp, waste more electricity than any other component (perhaps as much or even more than the rest of the system combined) and have a negative effect on the enviornment. Perhaps a suitable compromise is in order.
Should Class A Amps be left on??
Ok- Audiogon members need some advice here. Should Solid State Class A Amps be powered all the time? Have heard two school of thoughts on this. Apparently from what I have heard this is a moot question for Class A/B amps due to the usual low biasing of A/B Amps. From what I have been to learn so far Class A Amps should be left continously on.
