The Yamaha website says not. My guess: Yamaha realized that a significant percentage of RX-V6xx units are used as pre/pros, and decided that a 765/665 pair with common electronics was a cost effective way to exploit both markets more extensively.

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

I have not been able to locate a 765 manual; did you find one?

The amp sections are completely different, so it's more than just a little more power. The 765 is also larger and heavier. But as far as anyone can see on paper, the front end is the same. There may be subtle differences in features and function but the unavailable 765 manual makes that impossible to know.

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 HDMI 1080i/p sources (DTV and PS3) that would fill all of the HDMI inputs available in a V663.

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.

Also, can anyone answer my earlier question about the 665 - with its apparently "lesser" power supply and/or amps, does it run cooler than the previous xx3 series? I had a 661 (similar to the 663, I think) and it seemed to get pretty warm.

The 665 may de-interlace 480i to 480p when converting to digital from component. I'm not sure about the 663. 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.

If it's that bad, it would be best to simply not buy it!

How about just running component to HDMI conversion with no I/P conversion?

Seems like a pain to have to run both analog and digital to the TV. That's why I bought a receiver which could do component to HDMI. I bought an RX-V2700 though - I have not see how the 663 looks.

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?

Yes, but since I have only 1 HDMI cable routed to my PJ, an analog output from the AVR to the PJ is not in the works for me. However, both of my sources can output 480p, so de-interlacing shouldn't be an issue... 480p to AVR component input (663 or 665) gets converted to digital (de-interlacing not required), output through HDMI and then my PJ scales the 480p to 720p, correct?

I am aware of the benefits of running multiple inputs to your TV. But I have seen no reason for them in my setup. I am quite content with a single HDMI cable. I know other people's needs and wants are different.

What HiFi lists the 2009 UK Yamaha receiver releases as RX-V365, RX-V465, RX-V565, RX-V765, and RX-V1065 [which it says are all "generic European"], i.e., there will be no RX-V665 model released in the UK [maybe all of Europe?]

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!

Why would there be a difference in listening if the specs for amp are same for 565 and 665. May be at the store the 565 was connected to different set of speakers as compared to the one's 665 was connected to.

I do have 565 and I agree that sound was weak. I had to turn the volume to -10db for getting good sound and I see that the VOLUME CONTROL in the specs states -80db to +16.5db for both 565 and 665. Can anyone please respond? I need to return this and buy 665 if indeed it sounds better than 565. Its a shame that they are measuring amps ar 1KHZ.

Ok,
I don't now how this happened, but I can't seem to find the DOLBY DIGITAL Mode on my Yamaha RX-V665. I have been listening to dolby Digital for few weeks, and now all i see or can find is the STANDARD mode by pressing the "movie" button on the remote, sure, there are other modes, like adventure, and sports, etc., but how do i get back the dolby Digital mode. That seems to sound the best for TV/Cable broadcasts.. Thanks!
post #225 of 1926
Press the straight button on the remote control.
post #226 of 1926
Mark,
I repeatedly pushed the Straight button, and all I got was what was on before,like 7-ch stereo, did not work getting back the Dolby Digital mode.
7-ch Stereo,Straight,7-ch Stereo,Straight,7-ch Stereo,Straight,7-ch Stereo,Straight, and so on and so on. Thanks for trying.

You probably have it set to display the DSP program (e.g. Straight) rather than the Audio Decoder (e.g. Dolby Digital). Press the INFO button on the remote to change that. (Your source also needs to be sending a Dolby Digital signal.)

kriktsemaj99,

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!

7-ch stereo is the worst thing to use for TV. Use Dolby ProLogic PLIIx if you have a 7.1 system, use it for all sources.

You might also consider reading the manual.

There's no compelling reason to use any DSP modes at all, just the DD/DTS decoders.
post #230 of 1926
ok,will read manual...Again. Really does not tell HOW exactly to switch from mode to mode.
post #231 of 1926
In the Extended Surround mode, IMO, both the PLIIx-Movie, and the PLIIx-Music modes sound terrible. I think for listening to TV/Cable, all the sound comes from all the 6.1 Speakers in the 7 Channel Stereo Enhanced mode.

I just bought this receiver to replace a broken Denon 1909. It was much easier to set up than the Denon. I'm not sure if I should have bought it. It feels and looks cheaper than the Denon
post #233 of 1926
Hi! I need help... quick! I'm at best buy right NOW (typing this on my phone) and they have this receiver open box for $300 with the standard warranty. Honestly, I'm not good with specs and all the jazz. I am going to be running a 7.1 system, 2 Polk Monitor 60s, 2 Polk Monitor 50s, a Polk CS2 (center), 2 Polk Monitor 40s, and this 12" 800W sub: http://stores.channeladvisor.com/the...0%20Watt%20Sub


Will this receiver be sufficient to power this setup? Please help!
post #234 of 1926
yes. $300 for a 665 is a good deal. since it's OB make sure you get the remote and microphone.

Dude, that's awesome! I thought I was bad googling products on my phone while at BB... but asking a question on AVS and getting an answer a few minutes later, that's beautiful! Gotta love it. Enjoy your purchase!

So has anyone figured out if this receiver can matrix DTS-MA to 7.1? I have a Sony BDP-S350 player and the lack of this feature is what convinced me to get rid of my 663.

Yes...Go into the options setting...Go down to Extended Surround and choose PLIIx Movie setting. This will give you the 7.1 matrix DTS-MA...It will also work with Dolby True HD. IF you hit the info button on the remote and go to audio decoder it will read what decoder is bitstreamed and will also tell you if PLIIx is activated.

Ok so this must be an upgraded feature from the 663 because I could not so this with that receiver. I remember doing the PLIIX hoping that would work and it didn't. All I could ever get was 5.1 unless I had a 7.1 disc.
