The Yamaha RX-V663 thread. HDMI 1.3 upconversion, TrueHD, DTS MA decoding. - Page 357

The 667 and 765 have basically the same amp section. It's just smoke and mirrors to claim an extra 5W per channel for the 765, given that they have the same 400W electrical power consumption and both specs are for 20-20kHz, 0.08% THD, at 8 ohms.

On the other hand the 665 really is a weakling, with an integrated amp and 270W max power consumption. So they had to use 1kHz, 0.9% THD specs in order to claim 90W per channel. But Yamaha got so much criticism for pulling that trick on the 665, that it was relegated to the 567 and lower this year. The 667 is back to where the 663 was (or at least close to it).

ok... i im love with yamaha brand.. but a friend is selling a onkyo tx-sr607 at avery very good price..... i dont know if i should take it... is it good?? as good as the 663 or 667 ¿? thanks

Remember that the onkyo 607 doesn't have pre-outs, that yamaha does. So if you'll want to buy a separated amp for the future the onkyo won't work. Another thing is that the onkyos get a little hotter over the yamahas.

know i am down to the 667 and 765 any thoughs? please please please

i dont really understand all this tec stuff... at the end is the 667 a better buy than the 765? i have to decide in between one of the today or tomorrow.. haha

"Better buy" at what prices? the 765 has more power. the 667 is HDMI-1.4.

The 667 is more future proof, if the price is similar I'll vote for the newer model.

same price...


yes i think the same, plus as long as i understand the 765 is limited in the scene fuction, you cant program as well as 663 (i read the manual of 663/765/667 and in the scen fuction 663/667 are alike, 765 there isnt much to do in the scene fuction) that is important, because the wife.. hahaha... i dont whant to explain more than pushing a button for TV and a button for avr...

They're the same price and in some instances the 765 is more expensive. Losing a mere 5 watts and having the same exact amp section with an overall better unit in terms of feature and forward support doesn't really hurt either


Also FYI for those in the Bay Area, our Concord Fry's adjusted their pricing of the V667 because of me So if you're interested, go check them out.

Hi all...great forum, although rather huge thread. I've search through but can't find info...

Issue with sound output to tv. Cd/DVD player connected to the 663 via digital coax (and component -HDMI port carked it), then HDMI out to television. When playing both cd's and dvd's, am only receiving sound through to my Wharfedales, and not through the tv. Video is fine.

Any thoughts?

I never understand why anyone buys a quality AVR and then wants to run the audio through their TV speakers

But ... whatever ... read page 98 of your owner's manual and learn about the HDMI SET function. It selects either the RX-V663 for your HDMI audio out or "OTHER" for an external HDMI device such as your TV set.

Thanks for the reply Cavu. Already set to "Other" but for some reason it's not pushing through the audio signal.

Just so there's no confusion - CD/DVD ---Coax/Component---> RX-V663 ---HDMI---> TV

FYI, tv acts as centre channel. Reason enough mate.

Ok so I am thinking about buying a used 663. Got a few questions as I dont know much about this unit, and dont have time to read the countless numbers of pages in this thread so Im hoping you guys can help answer my question.

As far as firmwire updates go, how can you tell what your receiver has and what it needs? Iv know nothing about firmwire updates.
Ill be running this with definitive technology speakers (bp30,clr1000)
Are there any issues with running a sony bdp-s550 along side the 663?
What about an HD direct tv box?
Does the 663 have any room correction built in? If so how does it compare to the newer models such as the 767 or 765?
How is the video processing?
Are there any other issues that I should be aware of? Any at all?

Are you getting audio pass-through for HDMI inputs???

If so, but the non-HDMI inputs don't appear at the HDMI output, it could be because the 663 is not converting non-HDMI audio inputs to HDMI audio out.

The manual seems vague but provides the following guidance ...

Hmm, that certainly does look like HDMI input is the only signal passing to HDMI output for the audio. I missed that when browsing through the manual. I do have an updated audio signal flow diagram, but it still only shows the digital outputs (coax and optical) output to only digital audio, and not HDMI.

I am pretty sure had audio pass-through when dvd player was connected via HDMI. I just can't believe this unit cannot process digital audio input and output it via HDMI. Is there anyone out there that has this working, or a workaround for this??

I am using the coaxial out from the PC sound card(onboard) to the 663-since its an onboard card, its capable of just 2 channel output....is there anyway i can apply the sound field programs to output the audio via all speakers?

Yes, just use 7 channel enhanced instead of surround sound.

but the AVR is not allowing to do so mate....PCM lights up and when i turn the knob to select the sound field, it just displays "Not available".

Tried a few DTS bluray rips and audio is just coming out of the FR and FL speakers.

A few points.

1. If you choose other you will be limited to 2 channel PCM.

2. Television speakers are not very good and you will get better sound quality by simply setting center to NONE IMHO.

3. Coax audio in will not be sent to HDMI output, only HDMI in to HDMI output with regards to audio.

Mark

Have you already gone into the pc settings and changed the config from desktop speakers to another set up like 5.1?

Another way to look at is that you wouldn't have to spend very much money to buy a center speaker which would be better than the speakers in nearly all TVs.

Check the sample rate you are using on the digital output of your sound card.

Thanks Mark. That's essentially the answer that I was looking for, and supports what's in the manual. Not the one I wanted to hear though In any case, we are getting a replacement unit for the Cd/DVD player so it will be back to HDMI soon.

As for purchasing a centre speaker, this still to come when I have a unit big enough to fit! 2 channel is fine for now.

Thanks to everyone for their input.

One last thing. I know most of the arguments of HDMI vs digital interconnects...I have half decent gold plated HDMI vs Selby digital coax inputs and the Coax actually brightens up the sound a lot more than the HDMI cable. The way I understand it, should be similar audible reproduction correct (if cables of similar quality)?

Thanx mate...that solved it

Cool!

Quick question fellas:
Playing a Ps3 game and 5ch inputs light up with HDMI, ps3 set to pcm.
Got a 7.1 setup but rear speaker stay silent. Any way to get them all going?
663 is set to Dolby Pro Logic IIx.

Any siggestions? Should I switch to bitstream?

Do you have a fat ps3 or the new one.

sorry about that.. should have been more precise.. it's the fat one with 180gb hdrive

I don't think the fat one will bitstream. I thought that was a new feature in the slim.
Have you tried 7 channel enhancer?
I'm not sure why you are trying to do this to begin with. If you want accurate game play sound to detect objects around you let it stay 5.1. You cannot make it anymore accurate if the game is only 5.1 anyway.

Yeah, the fat is better to set it as PCM and in the menu use the Dolby pro logic IIx -movie mode, for 7.1. That's the way I have mine and works great. Remember if you don't have a external amp, when you use the 7.1, you only gets like 40 watts for channel, so it's better to live it as 5.1, that way you get for juice for your speakers.
