bryston warm up time

I bought a used Bryston amp about two months ago and noticed that it taked about 15 min to warm up. At first it sounds fuzzy and distorted. When it warms up it sounds as sweet as it should. I was wondering if this is normal or a sign that it should be looked at? The amp is from about the mid 90's

Thanks for your imput

5 - 15 min. is the usual warm up for SS amps. I don't think there is anything wrong with your amp.

15 minutes is nothing: 30 hours is nominal warmup to attain thermal stabilization. Leave the amp on all the time for best sound characteristic & longest service life.

Anywhere from twelve hours to two days (Naim amps, much digital gear) is required for thermal stabilization and full performance. This issue, and the related issue of whether leaving equipment turned on 24/7 prolongs its life, reappears continually on this site, for example:

That is why many recommend you leave SS amps on 24/7
