From my somewhat limited knowledge of electricity (I am a chemical and biomedical engineer and somehow survived EE class), 10 amps would translate to about 1200 watts. From looking at the 3 pieces I power from my HFC URH power conditioner, it only draws a few amps at rest, and with the 93 dB/1 watt sensitivity of my speakers, I doubt my power amp is outputting more than a few watts. So it seems as if 10 amps is quite a bit of current, but perhaps with inefficient speakers you could become current-limited. Any more than this and you might trip your electrical panel beakers, which I have never done. Is my thinking correct on this?
