Warm up time for amps


My amps ( I have many but as an example in this case Bryston 7b3's) seem to take a good 45 minutes to reach best sound. My question is ... how do I warm them up quicker? Is playing them on a revolving loop or shuttle BEFORE my listening starts the only option? If that is the case does playing at low volume achieve the same results, and/or does playing louder speed things up, and if so presumably the louder, the quicker in proportions?
And in that box, is the ambient temperature (eg summer or winter) a factor? To me, it should make no difference with all that stuff going on inside a confined space,  but someone will tell me otherwise? I could rig up small fan heaters to blow for ten minutes? If it cuts down warm up time by half for example it may not be such a  stupid or strange idea as I think it might be, as it would increase the proportion of "enjoyable" listening time substantially.
I could even be super smart by putting timers on the fans (which in case anyone points out a supply contamination issue ... could be on a different circuit entirely
The amps are rarely switched off.
This issue does frustrate. All that expensive kit not performing at best for a period ....

My experience with my McCormack amp is similar to what you’ve experienced with your 28bsst2s — about 20 minutes to settle despite leaving amp on 24/7.  I’d do two things.  First I’d call Bryston to see if there’s something specific to the 7b3 (how many Bryston amps do you own BTW???) that would cause this and what they’d recommend.  Second, and depending on what Bryston says, I’d leave a streamer or cheap Blu-ray playing 24/7 to make sure all the circuits are firing rather than the amp just being in “standby.”  I doubt this will have you at 100% right from the start, but I’d bet it cuts down your current wait time significantly.  Just some thoughts, and let us know whatever you find out.
