Summary: [Update] I found an article that explains the purpose of the Impedance Selector. Switching over to the 4-ohm setting actually DEGRADED the power, so the sound improvement was all in my mind. I also want to add that I've been considering an upgrade to the Yamaha A-S1000 integrated amp.
Summary: After going through a very frustrating experience with a lot of other Yamaha models, the RX-797 was an answer to my prayer. With a turntable and Bose 901 speakers I needed something with a pre-amp loop/tape monitor (so I can plug in the Bose equalizer) as well as a real "phono" input.

Summary: I bought this receiver to power an extensive multi-room household system. It has the power to do that -- actual output at 6 ohms is 120W per channel. It can easily power several rooms at a time.
Summary: I would highly recommend this stereo receiver, particularly if you want a solid two channel system that is able to drive high current into low impedance speakers without breaking a sweat [there is so much drive "head room" -- high dynamic power -- that you never get to distortion-causing "limiting"...
