Debate: Class D amps need 48 hours of warmup


Have you listened to your amps cold? Warm? Both ways?  What was your experience? I’ll hold my own observations to not bias the replies. 

Did you leave them off while on vacation and then come back to find they sounded hard and strident?

My Marantz PM10 stays on 24/7.  Although I can't say it sounded any different when it was first turned on after being off and unplugged for the best part of 6 months when we first arrived at our second home.  It just sounds good even in comparison to my much more expensive Class A tube main system.

At my age I can't hear the difference. I never leave my systems turned on at all times. If the you live it Cali don't let the Governor know this fact or you will be in BIG TR....killing our environment, shame on you.

Have always found SS amplifiers need a warm up time. My Benchmark needed about 15 minutes. Had an Aragon that needed about 30 minutes. I leave my Accuphase P4600 on all the time.
 

Aurender and MSB recommend  leaving their components on. And I do. 

Sometimes I leave my setup (SE class A preamp and class AB amps) turned on for days at a time, and sometimes I turn it off. 

I find that it sounds better when left on. Could be, since it's vintage gear, that I have marginal caps that need reforming to drift back into spec. I don't know
