Amp — Leave on or turn off

It is, as many stated, amp specific. I will add that it is also user specific. In my case the weekends are my music time, so my system is off all week. When I get home Friday night, I turn everything on and leave it until my weekend is over. My Macintosh gear always sounds better by Sunday. Could be the bourbon helps some. I am going to do more studies. Wish me luck.

Much has todo is how much power it sucks up ,A pure class A amp runs full bore so no to Thst one ,a class D amp if you wanted why not  a amp takes about 30 minutes to get to temp  and if newer the capacitors and transformers could take 

months to fully settle in. Depending how much you play it.

My Pass XA 60.8 power amps take an hour to warm up and the sound quality improves slghtly over the next hour. There are no further gains to be made from leaving the amplifiers on when not being used from listening - except for warming up the room, but that's a very expensive form of space heating and not recommended.

if it's a solid state amp it needs to be on all the time, I have a sim audio w8 and if I turn it off after 24 hours it needs to warm up for 3 days again before it sounds totally open again.

This thread is going EXACTLY the same way as the last one, and the one before that........    You say Tomato and I say Tomato.  You want to leave our equipment on, then leave it on.  You want to turn it off, then turn it off.  I doubt the argument has ever changed an opinion.  Time to move on to a new topic.  How about "do power cords make any difference?"  🤣 🤣 😭
