I bought one last week, and so far so good. I did the advanced MCACC setup, bi-amping the fronts with 5.1 surround. I plan to re-do it, though, after reading more about MCACC calibration in this thread: "OFFICIAL" Pioneer MCACC thread
One question I have: does anyone have any *true* power/output numbers for this receiver? As with most AV manufacturers, Pioneer uses the useless "@ 1kHz" rating, not full range. Can't find any other rated specs anywhere.
I had seriously considered the NAD T758 AV receiver, and would have bought that one if not for the drastic price reduction ($799 + free shipping) on Amazon last week. The NAD, which I was able to demo in-store, is fantastic. In addition to movies, I do plan to listen to a lot of music (2-channel mostly, but a few SACD and Blu-Ray Audio titles). It doesn't have as many features, but it has a great sounding amp (class AB instead of class D, so it runs hotter...I like the idea of a cooler running class D in the Pio), and they have honest power specs (110 watts per channel into 8 ohms (20-20,000 Hz) at 0.08% THD, with 2 channels driven). Plus, it has Audyssey room calibration, which by most accounts is superior to MCACC.
But, at the end of the day, I liked the added flexibility and future-proofing offered by the Pioneer, particularly for the discounted price. I like that it has pre-amp outs for every channel, so I can upgrade the amp(s) down the road and essentially use the Pioneer as an AV pre-amp. I don't plan to do that anytime soon, but it's great to know I have the option.
