I have a Yamaha RX-V1400. It's fine, but if you're interested in SACD or DVD-A surround music I recommend investigating a matching Denon amp and player. Having a single digital connection (DLink) vs analog is a major improvement in ease of setup and calibration.

If you have much stereo material and want surround from that, some people like Harmon Kardon's Logic 7 better than Dolby PLII.
