Amp — Leave on or turn off

I agree with both 12many and fuzztone ,  I turn my McCormack amp on about an hour before listening , enough time to warm up .

My AT3002 amp has a standby mode feature. I think it keeps the amps circuitry charged up some.

I usually turn it on about an hour before using.

On. 

It’s not a debate. It’s very much amplifier specific.

I have ICEpower amps and they absoultely need at least 72 hours to sound musical.

My Luxman warms up well in half an hour.

I have no real explanation for why some amps warm up faster than others. I do not believe this has anything to do with the amplifier class (A, A/B or D) either. I do think it probably has something to do with the capacitor types, and maybe how much power they draw at idle. Perhaps the Class D amps, being low power, take a lot longer to warm up because they literally don’t warm up?

I’ve also heard say certain megabuck amps simply don’t sound good until after 48 hours at least.

I think it’s very much specific to the amp.

I notice that my amp sounds better after I eat a croissant.

Coincidence?

Hard to say. ;-)
