"Official" Yamaha RX-V667/RX-V767 Thread

These models are Yamaha's step up from the 467/567. All evidence points to a welcome increase in the size of the power supply transformer. Compare the 667 to the 665. The 667 is 4.4 pounds more with the same cabinet size and has a higher power consumption. Good news, IMO.

I still can't find exact specs. Will post as soon as I get them.

* Decoding for all common codecs ( TrueHD, DTS-HD Master Audio, etc.)
* 5 AV inputs ( composite)
* Two digital; two coax inputs
* Audio return channel
* 2 Component video inputs
* HDMI 3D Support
* Can change inputs in standbye mode! (Nice feature if it works like I expect)
* Auto Power Down (Interesting feature?)
* Analog to HDMI (with 1080p upscaling)

So in terms of firmware upgradability what is expected?? Does yamaha releases regular firmwares for this range of receivers???

This raises a bit of a red flag. Depending on how it's configured, the ability to pass HDMI video untouched could be effected. IOW, you might have to choose between scaling all video or none instead of just scaling the analog inputs.

Considering the difference in size and weight, I find it hard to believe that the 667 and 767 will have the same amp sections. I'm assuming that the 767 is the same as the 765 in size/weight.

Thanks RD. I had not done my homework carefully enough. So what it looks they did, on the 667, was to cram a bigger power supply transformer in it, while keeping the same cabinet size.

I think someone at Yamaha must have noticed that people are not dumb. I sometimes think some CE employees get the idea they can skimp on power supply and no one will notice.

Just like previous models, Pure Direct should solve that. Or use the OSD to disable video upscaling.

As far as I can make out neither of these can upscale HDMI, they only upscale analogue inputs.

Also the main point of the 767 appears to be

2 HDMI ouputs with proper matrix switching, which means I can ditch my external matrix switcher.

and a tad more power per channel

I'm thinking of getting one to replace my Panasonic XR55, then I just need an Oppo and I can make wife friendly Blu-ray player

I will re-read the manual and try to come to terms with the scaling feature. I remember reading something in the manual which made me think HDMI to HDMI scaling was possible.

I have been wrong before though

They can upscale HDMI, but only for 480-line input resolution (scaling to 720p or 1080p). This is listed in the 667 specs. on the Yamaha web site. Not being able to upscale 720p to 1080p doesn't seem like a bit limitation.

567 has no 8-channel input according to this (the comparisons feature has been known to be wrong before)
The 667 has two more HDMI inputs
The 567 has no component video upscaling or HDMI upscaling
The 567 has no zone output
The 567 has no pre outs
The 567 is 4.5 pounds lighter, but has the same cabinet size - it's less powerful, in other words (you can also look at it's power consumption as a comparison)

In my opinion, the 667 is the better value for $120 more MSRP.

Actually, that has little to do with the size of the amp. It's caused by the lack of a delay - I forget the technical term - in the amp's switching in. AVRs use a relay that switches in the amp after it's powered up.

Inrush current may be the phrase you are thinking of.

With the 665 being one of the big let downs of last year, is good to see yamaha is putting real power back into it's entry level AVRs. Preamp outs are alot cheaper than a real power supply, but the new yamaha I bet still will only pump out 20 to 30 of real RMS power with all channels driven, but thats still alot better than the wimpy 665

Can you please explain how an all channel driven test is an indication of real RMS power? When would you drive all channels into clipping in a real world listening scenario? The Yamaha RX-V667 stacks up quite well to the Denon's (which you are a fanboy of) this year. 2 more HDMI inputs on the Yamaha. 2 component inputs and one component output (compared to the 1 component in of the 1911) 4 digital inputs on the Yamaha instead of 2 on the 1911.

Price being equal, is this likely to be a better option than a Denon AVR-2310CI? My Onkyo TX-SR606 has been acting up and I'm going to replace it, but I have very little experience buying these products.

Differences in audio quality aren't really a concern, my primary concerns are video quality, five or more HDMI inputs, two or more components inputs, and reliability.

Sorry if I'm asking a complete noob question, or one that's been answered a hundred times, I'm just under a bit of pressure to make a decision quickly to take advantage of a sale.

There is no perfect test, IMO of power. The reason why ACD is nice to have, is to compare two receivers, both spec'd really similar at say, around 100x7 watts. One might have double the power when you look at ACD. For example, one might be 25x7 the other 50x7. That does make a difference in real world power, IMO.

Or you could compare weights, cabinet sizes and power consumption to get an idea.

One measurement I think can be very misleading is stereo only power. Most receivers will meet their specs in that category, so what does it tell you? Not much, IMO. Two 100x7 watt receivers may both hit 100x2 watts. But one might be significantly better when watching a movie.

One other thing. If you ever use 7 channel stereo, some anemic 100x7 watt receiver which puts out 25 or less watts with seven channels driven may not meet your expecactions.

One thing to consider is that the Yamaha has pre-outs for connecting an external amplifier (if your current speakers need more power, should you ever want to upgrade speakers or add more speakers).

We're just about starting to see HDTV2 resolution (3840x2160) TVs appearing, which I expect to be followed shortly by BD players providing ('intelligent') output up scaling to the same resolution. So, given the reasonable life expectancy of an AVR purchased today, I would choose one with HDMI 1.4 so as to be able to switch video at HDTV2 resolution if/when I need it to do so.

ACD test's are a joke because thermal output is never measured and it is done over a single impedance. If company A decides to limit output when full cycle tests are done into clipping (thus protecting the amplifier) and Company B doesn't in order to look better on paper who's ahead? Certainly not the consumer. Google All Channels Driven Fallacy. You will learn that the amplifier that MIGHT spec worse in an ACD test might actually perform better in the real world, as it is designed to work in the real world (dynamics in volume and swing power from channel to channel). Don't take my words for it, google it. There was a lengthy article written about it over at Audioholics and it will really open some peoples eyes.

I have no idea as I haven't compared the two. If possible I would listen to them. I certainly wouldn't let ACD sway my opinion either way.

It is my opinion that all channels driven tests prove nothing about real world power. Gene at audioholics wrote a good article at the link below.

Does anyone have any information on the switches on the back of the receiver on the right side that refer to the ohm rating of the speakers? The pictures are blury and I can't seem to fing any information on it. Is this for selecting the ohm rating of the main speakers? If so, what options are available. I currently have 4 ohm mains, this is why I am asking.

Thanks, I checked it out and the receiver does support 4 ohm speakers! I went ahead and placed my order for one. I been ready to upgrade for a few years now, and I believe this has everything I need.

I was reading through the manual and it appears that you can have up to 9 speakers plus the sub connected at the same time. Am I reading this correctly, or am I missing something?
