bryston warm up time

I would check the Capacitors on this unit. Look for leaks on them. Solid state should not have that long of a warm up time. Tubes will have a stabilization period but I have never heard of SS having one. If you have an oscilloscope and a good meter you can measure the charge and decay of the caps. Use a grounding rod when discharging caps as to not get a generous surprise when you reach inside.

I agree w scrowley. Any SS amp should be ready to go in no more than 15 minutes. And if you have a power conditioner with a meter, you can tell when that is because the idling current draw settles down and stops fluctuating.

As for thermal stabilization, that's very nice but not really necessary for a SS amp (especially full Class A) to perform at its best. And unless the listening room's temperature is kept constant, the temperature at which the amp stabilizes will keep changing depending on the room temperature.

Scrowley also makes a good point about the caps. They might be taking longer to fully charge. However if the amp is still in warranty (20 years transferrable for Bryston), I'd suggest you send it in for routine service anyway. What's a little freight!?

Raquel is right . Real world situations , I have found at least an hour .

FWIW I never found Bryston to 'warm up'.

Sorry, someone had to bash them....

I used Bryston for years and found that they are best left on or warm them up for about 10 minutes before you use them. I would check your speaker connections just to make sure they are tight.
