    I was told by an Audio shop to leave my Rotel RMB 1066 AMP on even when not in use. I'm curious to how much juice does an AMP draw when not being used but turned on?

    Turn it off.
    All power amps will consume some power when idle. How much depends on the biasing (its quiescent point, or operating point with no signal) of the amp circuits. Higher quality amps tend to be biased more toward Class A, which consumes more power at all times- signal or not.
    Rotel's website doesn't list power consumption specs other than rated (700W- which is an "all channels driven into oblivion" type spec). As a guess, I would say this 6-channel amp consumes a MINIMUM of 75-100 watts at idle. Left on, that's up to 75kW-hrs per month.
    Audio shops seem to perpetuate the myth that there is a world of difference by leaving the amp on. While the most anal listener may notice the slightest difference, it isn't night and day. Simply put, how much additional natural resources are you willing to consume, for how little return?

    Well in my experience with my Acurus amps, cold vs.warm is night and day. I leave'em on(or at least the 2ch amp)all the time. However,though I have not checked,warm-up time is probably not all that long.
