The russound stuff looks intriguing from an ease-of-installation standpoint, but I can't imagine it sounding that good. It looks like it uses some sort of ethernet-type protocol for signal distribution and to intereact with the source control and then uses some tiny outboard "amplifier pads" mounted like light switches in individual rooms to get the juice to the actual speakers. Nifty design, but those little class D amps mounted in the space of a light switch probably don't sound so hot.
