Yamaha's comparison feature was not helpful. You might have to read the manuals.

The 663 does not do up-scaling, the 665 does. That's important to remember, cause any comparison is meaningless unless you turn off up-scaling in the 665. The conversion from analog to HDMI is probably similar in the 2 units though. The de-interlacing in either unit will be very bad, and it appears that neither will pass 480i with digital conversion turned on.

so the situation is unchanged from the 663 to 665, it's much better to pass analog as analog and let your monitor do the conversion and scaling.

I have two 480i/p sources (PS2 and SD-DVD), both with component outputs. The DVD is upconverting with HDMI output (480p/720p/1080i). If I went with 665, I'd use HDMI for convenience (1 less cable, I guess).

If I went with 663, these sources would send 480i/p into the 663 where the signals would be converted to digital and sent via HDMI, although still at the 480i/p resolution. My PJ would then scale the image to match its display resolution, which happens to be 720p. Am I understanding this correctly? So really, the only quantifiable benefit (for me) of the 665 would be one less cable, correct? Btw, my use for either one will be mainly as a pre/pro.

That is something you really do not want, since your display will do a much better job of de-interlacing. De-interlacing is the single most important step in upscaling to 1080. Again, the best solution is to output analog for analog inputs and digital for digital inputs. Even without de-interlacing, the digital conversion on either unit is less than great.

There are other reasons to run separate analog video to your monitor. For one, your monitor can set and remember calibration settings for different inputs. In particular, calibration for component and for HDMI can be quite different. If convenience is more important to you and if you're happy with the results then by all means use the upconversion. In order to get video processing that rivals your monitor's, you need to spend a great deal more than $500. Why bypass the better processing that you paid for in the monitor?

I was not jazzed about it's display and stripped down look, but the amp section seemed fine. I heard the NIN demo off Blu-ray, a track I know really well, and it sounded like it should.

The RX-V565 fared POORLY. I don't know what to say. I had the volume at -15 dB and it barely put out enough sound. Either there was something wrong with the 565 or it's hookup, or people should avoid it. Connection was digital, so that's not a problem. An Ultimate sales person said he set them both up, and that the 565 was just weak. I hope it's not as bad as that demo would indicate. Having to turn up a Yamaha AVR with a Dolby Digital source off a Blu-ray disc to almost 0 dB to get some sound out of it seems crazy!

Got it. Thanks for the tip. Just beginning to understand this 665 AVR. All the other surround modes like adventure,chamber, sports,etc., seem to be terribly be too echo-y. So I'm using the 7 ch. Stereo for TV Cablr broadcast, which doesn't sound any different than the dolby Digital.

On playing a blu-ray, Do I have to change it back from Dolby Digital to DSP?

is it true that the receiver will apply a DSP or doing channel duplication of some sort in order to produce a 7.1 output from a 5.1 source?

Thanks again!

Will this receiver be sufficient to power this setup? Please help!

IF you hit the info button on the remote and go to audio decoder it will read what decoder is activated and will also tell you if PLIIx is activated.
