Musical Fidelity A220 integrated amp

@voodoolounge  - I do not have that amp, so no relevant experience. However, I do have a Rega Elicit-R integrated amp which sounds best after being powered up for hours. Because of this, I leave it powered-on 24X7, unless I'm going to be away from home for a while. I do listen to it daily, so being powered-on all the time is my best solution...

That's the way with effin A. You gotta pay to play.

If you can afford to leave it on, run it into a load for less parts kill heat.

My gear sounds better too after it's been on a while...there is endless repetitive debate here about whether or not this is real...Odyssey recommends I leave amp on all the time, there is no standby switch...my old Portal the same

The mid range is more focused and instrument separation clearly improves. It seems much brighter when turned on and than after an hour or two sounds warmer and relaxed. I agree that leaving it on would be best, I listen when I get the urge through out the day and evening. 

It's over 20 years old and original, so I'm worried leaving it on always will retire it sooner.
