A general rule of thumb about SS amps is that the hotter that they run in normal use, the greater the sound variance when going from off to normal operating temperature. In other words, don't expect the same sound out of a high bias amp when it is stone cold or warming up. It may take several hours of consecutive operaton to come up to operating temperature and fully stabilize.
Amps that run cool i.e. Sunfire, Bel Canto or other "digital" or "switching amps" will not be as noticeable when going from cold to hot. Since they stay relatively cool even when "throttling" them, they don't need as much "warm up" or "operating time" to stabilize. Then again, these amps are so efficient that you can leave them on and they pull less power than a normal light bulb. For the record, the Sunfire 2 ch amps idle at about 40 watts of consumption. The B & K will idle at QUITE a bit more power than that and runs WAY hotter, even at idle.
Like anything else, it all boils down to personal choice. As for me, my house looks like an audio showroom due to all of the lights and displays being lit up all the time. Sean
