Debate: Class D amps need 48 hours of warmup

24/7 baby 

(Facepalm)..

Play this Megadeth track 2 or 3 times at 95 db or 100 db and your amp should heat up in no time...shouldn't take more than 10 mins

Everything should be warm in a jiffy, no problem. You reallyyyyy don’t have to meditate for 48 hours waiting for some goofy amp to warm up.

I leave my AGD Duets on stand by all of the time, so I haven't tried them from a "cold" start except when I first bought them. Then they definitely sounded better over time. Part of the burn-in process I guess, between the amps and the stock power cords.

Hey @deep_333 as an engineer, of course I get what you are saying.  Temperature wise the system should be thermally stable within less than half an hour, if not much shorter.

So try to avoid giving yourself a concussion, but truth is myself and others, specifically with ICEpower based amps hear a noticeable benefit in leaving the amps on for more than 24 hours. 

I don't actually know why.  I call it "warm up" for lack of a better word, but it's unlikely to actually be purely a temperature thing, unless there's some odd component that is kind of thermally isolated which would explain it. 

All I can say is my engineering knowledge and my actual listening experience have not lined up. 

Are you a registered professional engineer, or do you just call yourself an engineer?
