At 480i, the RP-91 is top shelf IMHO.
at 480P, the other Panny siblings do an outstanding job.
At 720p & 1080i over DVI, I just replaced my RP-91 with a Denon 2910 and I am very impressed.
A huge improvement in both resolution/clarity as well as a much more HD-esque reproduction of gamma.
I am running the 2910 into a HT1000 DLP which has it's own DCDi processing. I can tell very little difference between 720p and 1080i, with the 1080i having just a very small touch of alaising, and I mean a very small amount.
I was able to use the HT1000 onboard image zoom, to watch a frozen frame from the 2910 via S-video, 480P, 720P and 1080i DVI.
S-video was the worse, but still very close to the 480P DVI image. The 720p & 1080i were so much better, it was no contest. But again, the 1080i was just a tad less smooth than the 720p. This must be a very slight advantage of the 2910 FLI-2310 over the HT1000 FLI-2200. (I think the HT1000 uses the FLI-2200 processing)
I have checked for macroblocking and I have not been able to get any of the traditional offenders to produce MB.
The 2910 also has 2 areas for dropping the black level, but I still needed go into the HT1000 RGB contrast/brightness controls to dial in lower/upper peaks as well as overall color temperature.
Mose of the fancy image controls on the 2910 do not function over DVI, such as gamma, sharpness and some others. A shame.
I give the 2910 2 thumbs up.
I do plan to try the Panny S97 ASAP, and I would be impressed if it hangs with the 2910 for half the cabbage.
BTW... if anyone is interested in my RP-91, drop me an email at [email protected]
. It has the V.256 software installed and it was purchased from Crutchfield.
