	I leave my preamp (Thaedra Servo-loop Class A) and amp (Bryston 3B)
on 24-hours a day, 7 days a week. Analogic circuitry is in a stable state
when temperatures have reached their operating levels. In the case of my
preamp, this is around 50 degrees celsius (yes, class A runs hot). From a cold
start, it takes about one hour to reach this temperature, and the sound isn't
really there until then, so I leave it on. The  idle wattage of both components
is about 120 watts, so the electricity bill isn't affected very much.

	I also read on numerous occasions that temperature gradients (going
from hot to cold to hot) are the single most important cause of equipment 
aging and gradual loss of performance.
