I recently bought a 590 as a secondary system and using it to drive Energy Take Classic speakers. Batpig's guide and the Audyssey instructions saved me a lot of time and confusion (thank you!). Since I only have 5.1 and listen at moderate volume levels, the 590 does a very good job for my needs. This Denon is my first departure from Yamaha equipment. The newer models (from all brands) have really taken many measures to reduce cost. At least the Denon has binding posts for all the speakers (unlike the lower end Yamahas) but the plastic front and knobs are tough to get used to. For $300 I got good audio and a great feature set, so I can't complain. I don't know if I'm just lucky, but I've had no problems with my HDMI equipment (HTPC, Xbox360, HD-DVD). I suspect that most people don't care, but the FM tuner is rather poor. Maybe it's just part of the industry wide cost reductions, but the tuner is noisier and less sensitive that my old Yam HTR-5280, which was worse than my Yam T-700. For people who are looking for a system to grow with, the 590 will probably be too limiting (no pre-amp outs or video select, 75W limitation, etc.). I'm satisfied with it, and I'll have to take a close look at the Denon line when time comes to replace my Yam receiver.
