My Classe amps seem to like a good 20 minutes before they settle down.
I usually deal with disappointment bias, and I am not joking. I am pleased when I'm not let down by a changeout.Aside from technical aspects of warm up and internal voltage stabilization, there are always psycho-acoustics at play. If the listener believes that a warmed up amp sounds better, it will sound better. That's expectation bias. You might snicker at the thought but this subjective dynamic is in my opinion a real phenomena.

Not yet, hoping never.Disappointment bias (def): When an AKer tries to adjust the bias pot and accidentally shorts a driver which in turn takes out the entire output stage with a massive bang followed by a large plume of acrid smoke.
The amp I've been tweaking has the trimpots with little fingertip wheels
I never consider "warm up time". But ime, regardless of amp, it's after the 5th tune that the system seems to be running at it's best. I do listen at loud 100+ db spl at my listening chair, though. So the system as a whole could be responsible rather than just the amp.Hi Guys I own an Adcom rack mount face GFA-555 that I bought from Audio Classics about 10/12 years ago.Sight and sound unseen just on reputation alone. I've had absolutely no problems w/ the amp and we already discussed the spooling down noise that I get through my speakers but is there a warm up time for a solid state amp? I contend I hear absolutely no difference from power up through xx hours of warmed up running time. My amp also powers up immediately w/ no lag what so ever. Is this normal to an Adcom and to solid state amps in general. Obviously there is clearly a defined warm up time for tubed gear which is apples and oranges. Do I have the cleanest most responsive GFA55 ever made or they all do this?

Onkyo believes in careful cold startup and pre conditioning with the M-510.

Do you have a PDF (or other medium) of this entire M-510 Start Up Procedure article? I acquired this amp a while back and want to keep it in proper functioning order through proper start-up and use. Thanks.

The process is timed, during which the bias to the drivers and outputs is increased. It returns to normal after the status bar on the front is all lit.
If a small cap replacement and service bulletin update had not yet been done to the amp, it is a MUST DO!
