Amps

it depends on the amp - what amp are you talking about

Forgot to mention the Mac amps were tubed! This guy had them stuffed under a bookcase or someplace he couldn't get to them so he just left them on.

Yes if they are SS since the caps take awhile to really sound good so leave the SS amps on and the tubed amps off but let the tubes warm up for at least 30 to 60 minutes for best sound.

This question comes up every three or four months.

Use the search field above.

Simple answer, yes, if solid state and you have some surge/spike protection.

Turn off, if you are not listening for a week, or more.

It’s a bit of a tradeoff. Really depends a lot on the amp.

Tubes age much more quickly than solid state. The inrush current for an amp can be detrimental to the supply caps and rectifier, son in that sense leaving a SS amp longer can be best. 

Generally speaking though for tubes, no, don’t leave them on all the time. For SS depends. I have Class D amps that take days to warm up. Best left on, consume very little power. My A/B Luxman integrated is ready almost instantly. No reason to leave it on.
