Pioneer SC68 9.1 A/V Receiver

Pioneer has been revising and refining their Class D amplifier technology inside of their Elite receivers for a few years now. The performance has kept improving, as it is one of the few receivers out there that actually delivers its rated power output into all channels at once. Pioneer's SC68 is a 9.1 receiver, and yes, there are nine power amplifiers in there, rated at 140 watts each. It weighs only 39 pounds. How do they get that much power in a 39 pound package? The Class D amplifiers.
