Summary: I won't repeat all the good things others have said. I have had mine for 6 months and I agree. It does run a bit hot, but I have not seen any of the other issues. It is also on the big and heavy side. The one issue I have that I have not seen discussed is that it is sensitive to HDMI loops. I discovered this when I wanted to use my blue-ray player with the superior video processing (Oppo 103D) to process video signals (e.g. cable TV).
Summary: First off the receiver arrived on time and was well packaged I got it for $1200.00. I couldn't pass that up. I am running my panasonic 60" gt50 through this receiver. I am havibng some troulble on the audio. whenever music plays in the movie the sound is great but the talking is not coming through. Sometimes I can get everything to work just fine, but it takes awhile. What I mean is this receiver has a lot and i do mean a lot of different combinations.
Summary: I was going to buy an Anthem pre/pro and ??? 7ch amp to replace my aging Denon which lacks HDMI, but my theatre is not yet finished so I bought the Onkyo to tide me over, assuming I'd need to replace it later. Well I don't think that'll be necessary. It's not great out of the box, but after a full 8 position Audyssey XT32 calibration it's brilliant, with bass resolution and vocal clarity I've not heard in my system before.
Summary: the title says it all. has just about every bell and whistle in a mainstream receiver besides 11 channel capability. honestly, i did not know it was going to be this good. if i had to do it all over again, i would've got the 5009 which is a several hundred dollar upgrade for having a toroidal transformer and a few other minute details, the toroidal transformer being the reason and brunt of the upgrade.
Summary: Purcahsed from Amazon. Have had this for about a week. Updated firmware right away with USB flash drive...no issues. Set up Audyssey XT32...awesome. I have Epson 8500UB projector, Pioneer BDP-320 blu ray player, Klipsch Icon V setup (bi-amped vf-36's, vc-25, vs-14's), bic f12 subwoofer. Sound is clear and crisp. Video was great before...now spectacular. Audio was great before, now spectacular.
