I have not seen any delay either. And as noted, the Reon chip is good for this price range. We need to compare apples to apples. It runs REALLY hot. It needs to be in a ventilated cabinet without anything above it.

I haven't experienced any kind of a/v delay on my 875. However, the system can be adjusted to sync the audio to the video. Also, rather than looking at the Reon chip as a con, it would be better to look at it as a pro since the 905 and the 875 are the only receivers in this price range to offer this level of video processing. Seriously, it is very nearly the level of performance of the Realta chip which presently is only available in the Denon AVR-5803 at $5200 MSRP. Not even the Denon AVR-4308CI at $2500 MSRP offers this level of video performance, and I think that the Onkyos sound at least as good if not better, depending on the speakers being used.

Quick question: what is the Realta video processor? is it a lot better than the Reon-HQV?

Is there really a delay between audio/video? when is it apparent, seems like a very big problem. Is this present in the 875?

After doing some research I have to specify one thing about HDMI to HDMI upscaling :

- Onkyo's 2007 AVR (as far as I know 875 & 905) will do HDMI to HDMI upscaling
- Actually this is a rare feature within the Denon 2007 lineup because only the 5308Ci will do the job

If I was committed to buying an Onkyo, the 905 is the one that I would choose. Having the extra HDMI input is almost a necessity, and the network features are very nice as well. However, I would submit that the Denon AVR-4308CI and the Yamaha RX-V3800 as well as the Pioneer Elite VSX-94 (I seriously can't keep up with all the extra letter Pioneer tacks on to their model numbering system) are more direct competitors in terms of price and features. That being said, I really wish that everyone would get on board with what Pioneer Elite has done: not insist on assigning the HDMI inputs to a fixed input designation. In the Pioneer Elite VSX-84, this effectively means that you have 11 video inputs from which to choose - 7 analog with assignable component video PLUS 4 HDMI inputs. Hopefully this feature remains with the VSX-9x series as well.

Ya, that was just a mental block. I'm the one who wrote the descriptions for the 905 and 605. I just got confused, I suppose. TRANSCODE != UPSCALE

07/26/2007 05:35

Erik...Just to clarify...The Tx-SR605 does NOT "up-rez" or scale video to 1080P over HDMI. Only the "875" and "905" in this series have the Silicon Optix REON Vx chip that does this. The Faroudja DCDi doesn't do 1080P, it's a limitation of the chip. It will do up to 1080i or 720P though. The "605" will, however, pass any 1080P signal input into it's HDMI inputs untouched to it's HDMI output. If you want 1080P, scaled from any source you plug in, regardless of input and source, then the 875 is your best choice. Or, if you have a fat wallet, the 905 adds a few nice new features that may or may not be beneficial to your setup.

It comes out in stores mid-August apparently. I haven't been able to find any reviews from anyone online who's been fortunate enough to get a preview. You could try the AVS Forum link listed above and see if you can get more info.

Ya, it's expensive in an absolute sense, but it's a pretty decent price for its competition. Personally, I would go for the TX-SR605 at $500.
