Debate: Class D amps need 48 hours of warmup

48 hours??  Absolutely unfounded.  Hope Gemini won't pick up this.

OK, guys, I know this is sounds like a weird question, but lets’ not attack the replies, or even the author, until we’ve seen informed replies.  This kind of judgementalism is really not what I was looking for when I posted. 

Nobody is attacking anybody here.  You’ve somehow made this up in your own mind.  

I swear my ice power sound better after days playing music.  Like 3 or 4 days. 

@soix and lets keep it that way. 

@jbuhl - That's exactly my experience, but it's limited to ICEpower.  My Hypex, cold sound better, but do seem to benefit from playing all night long.  You and I are not the only one's who've made that observation about ICEpower specifically.  I was kind of wondering if it was something unique to the brand and was really hoping others with other brands have had a chance to experiment.  

In my case, I found this out by accident.  I would normally leave4 my amps running all the time,  but when  I went away for a vacation I unplugged my whole rack. I came back and I thought something was broken.  I wonder also if certain class D amps take that long to warm up if it could be part of the complaints users have. 

No experience with class D amps but every Class A or A/B amplifier ever owned tube or solid state needed at least about an hour to sound its bes. As to Class D, I would think that you can just keep it on 24/7 no?

@erik_squires after an extended period of time unplugged the amp or dac or preamp takes longer I agree. At least 24 hrs.
