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?

The HIFI Rose RA280 sound pretty good after the third songs out of the box. It plays many times for the last few months. It is getting less digital like and more tube like compares to my Muzishare RA100+X9 combo. Each time only take a few songs to make me forgot it is solid state amp, just a very good integrated amp. 

Mine power up instantly. They do not run warm so waiting for warm up is not logical. 

I own(ed) six different class d  amplifiers, all of them need very considerable amount of time to sound at their best. I also own(ed) class a class a b, tube amplifiers, they need drastically less time to sound at the best, and the tube ones are the fastest  in warming up, except that you need to wait a few minutes before the tubes get hot enough.

(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.
