Power Consumption idle

Is this right? I have a Sim Audio Titan 7ch solid state amp and the specs say the amp uses 75 watts at idle. I am just trying to figure out why my electric bill is so high.

I know having the gear on always, but this aside, can 75 watts keep a 19x12x27 120lbs piece of metal good and warm to the touch? Or could the specs be very misleading.

Thanks
Marty
