Parasound Goes Three Channel

Good things come in threes, and in this case it's Parasound's new three-channel Halo A31 amplifier ($3000, available soon). It's essentially a three-channel version of Parasound's highly-regarded Halo A21 stereo amp, and a cousin to the company's Halo A51 five-channel design. Why would you want a three-channel amp? To locate your front channel amps up front and your surround amps in the rear where they can benefit from shorter cable runs to the surround speakers. Or perhaps you don't need as much power in back, or already have a decent stereo amp you can use there.
