I used to own these amps and I can tell you that they definitely sound better after an hour or so than they do when they are first turned on. By this time the output transformers are nice and hot. The biggest changes happen in the first 10 minutes but the amp continues to get better and better up to 60 minutes.
Cary have a startup sequence that you should follow if you want to preserve the life of your tubes. Turn the amp on, but into standby mode. This turns on the heaters in the tubes. After a couple of minutes, flick the amps off standby.
I had no issues with my amp. It was absolutely reliable.
