Well, I got my 606 (R&J) Monday evening but didn't have a chance to hook up till last night. Running a Toshiba (1080p upconverting) DVD player $59.99 from Costco via HDMI to 52XBR Sony (will be shopping for a BD after new models are out this summer). Running 5.1 speaker system till I decide on new surround and back surround speakers (will move the old surrounds into zone 2 in our dining room for my wife) (Hey while I'm up in the attic running wires - I might as well run a few more sets to places I might later want speakers). The 606 replaces an old Aiwa surround receiver. My impressions - almost entirely favorable are;
1. After tuning with the Audessey system and viewing a number of scenes from some of our favorite DVDs the sound system is seamless. It handles everything from space battles to dinosaur bellows to rustling leaves in romantic comedies with equal aplomb. The best compliment I can give the receiver is the sound blends with the video - you hear the sound but it's not the sound for sound sake but all part of the movie scene. The Audessey EQ also seems to keep the center channel dialogue understandable at low volume levels while still blending with the other sound - something I've always had trouble with. I've been using bitstream from the player to the Onk.
2. Musically, I don't think our CDs have ever sounded as good.
3. At first it's a little bit of a hassle pounding through the various sound modes for each source, but I seem to find one or two that do sound better for the source than others. I assume I'll eventually find a default mode to program in for each source over time.
4. Mine gets warm but after using for some 6 hours straight with some demanding driving of the sound system. It was warm, but I could easily hold my hand on it and on a cool fall day it would have felt quite nice! Driving two more speakers may add some more heat load, but I don't expect it to be excessive.
5. My only complaint so far and believe me it's a minor one is the FM antennae wire they gave me didn't work for spit! Half of my wife's favorite FM stations were so bad I gave up. I took the old dipole antennae I had, put a 300 ohm to 75 ohm transformer that I had on it and plugged it back in. With that, all her favorites but one was back.
My experience with the set up and initial installation are that the receiver is quite a good value for the money. Its manual is reasonably well written as I was able to work my way through without any major hiccups - I'm an engineer but not in the electronics arena and certainly no audiophile. I'm happy and shouldn't get receiver-it is for a year or two!
