I have a kill-a-watt and checked my 7100 when I first received it. I was rather surprised to see it was slightly over 100 watts at idle. With the energy crisis this country and the world will be facing in the years ahead I could never in good conscience leave this, or any other device turned on for no good reason. So the 7100 is on when I am listening to it and off the rest of the time.

BTW, max current draw is 1200W but it is not likely most will get anywhere near this figure with average speakers at normal listening levels.
