Brilliant.
Bottom line: the sound is exquisite. Mind you, my 808 is pushing some excellent Monitor Audio RS6s (5.1 setup), and they speak to one another spectacularly. Tight highs and sweet lows.
Onkyo has created an AVR that is sensitive and capable of detecting subtle nuances. Here are three examples:
Dark Knight (Blue-Ray): crisp sound and noticable improvement visually. The very slight pixelation of my five year old Panny plasma was made indiscernible by the 808′s wonderful Faroudja DCDi. Furthermore, the rumble of Batman’s tumbler is awesome.
Pearl Jam: Immagine in Cornice (DVD): upconverts to 1080p impeccably. You are surrounded by the audience to amazing effect. Goosebumps. Beautiful.
Red Dead Redemption (first gen X-Box 360/ no HDMI): Sound vastly improved. Can’t say I noticed any visual distinctions, but that’s not surprising as it is not HDMI. Having said that, audiophiles will certainly enjoy hearing the gentle grinding of dust and dirt under the protagonist’s tarnished leather boot. Gun blasts are deep and penetrating.
Overall I am very pleased with this product. I’ve not experienced any of the aforementioned problems–i.e. NO BUGS! Even the networked sites are quick and fun to play with.
To quote The Dude: “It really tied the room together” (Coen 1998).

I just received the Onkyo TX-NR808 this morning and took 2 hours of hook up. There was a few items that prevented me from giving this receiver 5 STARS. One was hooking up the speaker wires to surround inputs. The right and left were NOT beside it other but were at one end and the other end. This leaves wire management with wire ties a mess. There was no input switch for my amps to turn on, (like my Yamaha). And last BUT not least was the microphone for calibrating the audio portion, (IT DID NOT WORK). And because it’s a holiday, I have to wait till Tuesday, July 6th to get a new microphone. So I manually calibrated with my Radio Shack Digital Sound Level Meter. It worked pretty good but time consumming. The great thing about the receiver was the 3D pass thru from my Samsung bluray player. I watched Monsters vs Aliens and Cloudy with a chance of Meatballs in 3D and was very impressed. With the new complaint (1.4A) for 3D content, it WILL catch on for the future. I just HOPE that this Onkyo will keep me smiling for years to come. Update: I had to return the receiver to Amazon today (07/14/10) because NO customer support other than ship it back to us for repair. I tried to MANY times on resolving the calibration with the microphone issue. I just received the 2nd one yesterday and the receiver still doesn’t work. Onkyo says ship it back to us. It is $50 for UPS ground delivery. It might take 2 to 4 weeks. I said NO and returned it back to Amazon. GET IT RIGHT BEFORE YOU PUT IT ON THE MARKET. This receiver went from a FOUR STAR, to a ONE STAR RATING. TERRIBLE CUSTOMER SERVICE.

Just hooked it up today. Takes over six seconds to switch between video inputs – totally unacceptable.
Update: I’ve tried 5 different TVs to verify and indeed any non-HD video cripples the unit. You television will show “no signal” and then come on, then “no signal”, then finally on.
S-video comes in as black and white and then flicks off then a few colors, then finally full color – entire process takes over 30 seconds.
“Upconversion” of S-video to HDMI should be called “downconversion”. S-video through the Onkyo to an HDTV doesn’t look as good as pass-thru to a tube TV – text is much harder to read.
The amp is very good. Sound quality is terrific.
User interface on the setup menu is well done.
Unfortunately I bought this very expensive amp for its video switching and upcoversion capabilities which have significant issues.
As a side note, read the following FAQ from Onkyo’s support website – even component video connections have trouble.
When I connect my cable/satellite box via component through the receiver and use HDMI from the receiver to my TV it displays 720p when the broadcast is 1080i. Why is that happening?
This is a limitation of the Faroudja DCDi chip used in the Onkyo receivers. Incoming 1080i signals via component connection can only be transmitted via HDMI in 720p. Incoming 1080i signals via an HDMI connection will be transmitted in 1080i.
The following hook up recommendations will allow you to display 1080i resolutions from your cable/satellite.
1. If the cable/satellite has the options of HDMI or DVI outputs, use those connections instead of the component video. The HDMI connection will allow audio and video signals to be sent thought a single connection. The DVI connection is for video only. You will need a DVI to HDMI adaptor plus a separate audio connection to go from the cable/satellite box the receiver for sound.
2. if your cable/satellite only supports component video then you can either go component video out along with the HDMI from the receiver to the TV. Or you can go from the cable/ satellite direct into the TV with the component video so you can get the 1080i signal from the broadcasts.
