Which is counter-intuitive. You'd think people who are able to afford a $1500 amplifier for their home theater system would likely also be able to afford a newer house with newer wiring in an area with a more stable power grid, etc. So I'd expect to see less variation of this nature. Of course, that might just mean that my expectations are wrong. But I don't recall seeing much in the way of griping about hum and ground loops with previous incarnations of Outlaw amps.

Cheers,
