Debate: Class D amps need 48 hours of warmup

(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?

Hi @lanx0003  - You caught me. I only worked as one ages ago.  These days I’m more into software.  I used to work on motion picture audio equipment back in the day.  Electrical, PCB and mechanical engineering of gear, and sometimes the installation too. 

It would have been more correct for me to say something like "from an engineering perspective, I have no way to explain the reason why these amps seem to need the time they do, and yet I still hear it."

Best,
