Thanks for the helpful comments below - another question I have is if I
would leave a valve amp on all the time or switch it off and have to wait
for it to warm up every time I need it?

**ALL power amps should be switched off, until they are required for use.

Hooey.

There are several reasons for this:
* Leaving an amp switched on, accelerates wear and tear on several parts. In
SS amps, this means electrolytic caps. In valve amps, this means valves and
electrolytic caps.

Hooey. If it's not a class A amp, or otherwise warm inside, it puts
less strain on the caps to leave them switched on. Start-up surges are
a major cause of cap failure.

My Audiolab 8000P has been switched on for about eight years, and
works just fine. I don't leave the Krell switched on, because it's a
true class A design, and pulls 300 watts from the wall at idle!

* Leaving the amp switched on, leaves the amp open to line surges and
spikes, which may damage equipment.

Only badly designed equipment, and not everywhere has such crappy
mains that this is an issue.

* Leaving the amp switched on is not environmentally sensitive.

Neither is farting, but I doubt it's a major issue.

Tell me again why you would buy an amp, without first listening to it?
Tell my why you think this is a good idea?

Seems like a bad idea - much like attempting to drive any decent
speaker with a cheap valve amp, when the same money would buy you a
sonically transparent SS amp.
