The funny thing is, it's not spending the money that's giving me pause, it's the fact that I would have to replace my Bell'O glass-shelved rack (because it's only rated for 50lbs per shelf) and possible electrical concerns.

OK, electrical question for the experts:

I currently have ALL of my equipment on one outlet through a Belkin unit.

Does adding an amp like this increase demands for A/C power (due to various efficiencies or more power supplies) over running a receiver alone?

Or, is it one of those situations where, if I was running the system at 95dB, it doesn't really matter if the watts necessary to achieve that volume are all drawn from the receiver or split between a receiver and an amp?

The answer might determine a purchase, because I wanted to replace that rack at some point anyway....!
