1. How many of you leave your amplifiers/receivers on all the time? I read somewhere that this prolongs the life of your gear. I take it that if there's any advantage to doing this, it doesn't apply to other components like your cd player, tape deck, etc. Funny, I always thought it was the other way around, but then I'm technically clueless. I noticed that my sub goes into standby automatically if there's no signal for 10 minutes, so maybe "standby" is not the same as "off?" 2. Is there any advantage to unplugging (or switching off the power strip) electronics while not in use, other than additonal surge protection? 3. On a related note: how many of you leave your desktop PCs on all the time? What are the pros and cons of this?
