Another Mini Review Ė Yamaha RX-V661 - 05/18/07 08:51 PM

Not to bore anyone with my story of bad luck and troubles with receivers, the short story for my buying this receiver is to tide me over while my Marantz SR 8001 is in the shop getting repaired.

Physical / build quality Ė

Considering that I paid $499 shipped to my door for this receiver, I wasnít expecting much. I wasnít disappointed when I pulled it out of the box either. The 661 is one of the lightest receivers Iíve ever had. Closer touching and feeling of this thing confirmed my initial thoughts that the sheet metal case and front panel are made of fairly light weight metal. The control knobs turn just fine and donít feel cheesy, but Yamaha could have made them a bit more robust. Good thing we all use remotes nowadays because I doubt these knobs will take much abuse. The speaker binding posts are pathetic but they do accommodate banana jacks, so thatís a plus. They are plastic with an aluminum lining. This is one bitch I have with my Marantz too. All my HK's had stout as hell binding posts with gold plated inserts. The power cord isnít much thicker than a lamp cord, so I suspect the power supply isnít very taxing. Moving onÖÖ

Connections Ė

Not too many gazintas and gazoutas on this thing, but how many does one need anyway? Iím just used to seeing receivers with many more. The important thing for me is it has two HMDI inputs and one HDMI output. The HDMI version is 1.2a. It also has a component video output, which is a really good thing because the OSD and set up menu do not output over HDMI. Without the component output to my projector, Iíd have been pissed trying to set this thing up. For more info on the inputs / outputs, you can hop on over to Yamaha.com or try to make them out on my crappy pictures below.

Set up Ė

For those who donít know already, I use a stand alone video processor (DVDO VP-50). All my sources go to the VP first, and it has one HMDI output that goes to my receiver. From the receiver, an HDMI cable goes to my projector. I have the VPís output set to 1080P/24 Blue Ray and HD/DVD and 1080P/60 for and satellite and SD/DVD. The receiver does nothing more than strip the audio off the HDMI feed and passes the video stream on to my projector. It is very important to me to have a receiver that will pass 1080P without molesting it. The 661 appears to pass it without issue.

Set up is pretty darn simple. Any idiot can do within minutes. The manual isnít all that bad to follow, but I didnít really read it so I reckon Iíll find out exacly how good it is sooner or later. I used the auto set up feature to see how close it would get everything. I plugged in the little mic and in about five minutes, the dead was done. It got all the distances spot on and the DB level of each speaker was perfect. The sub however was all screwed up. It put the sub at 1 foot, so I changed that to 16í (ten feet away + 6í). It also had every speaker set to largeÖ..weird. I havenít seen that trick before either. I eventually changed them all to small and set the X-over to 80. I wanted to hear it as is first and will get to that in a minute.

This thing has a gazillion different pre-set parameters for all sorts of different sound fields. I flipped through some of them and was farly impressed. Some sound pretty darn good, and some down right suck too thoughÖ.You can set this receiver up to have different sound fields with different inputs and even tweak them to your liking. I donít have patience for that crap, so itís running straight right now.

Performance Ė

Again, for those who donít know, I have M80 mains and I run a set of M22ís in Parallel for my center channel for a 4 ohm front wall load. I was curious to see if this receiver would drive them, and if it would, just how well. With the mains set to large still, I popped in the SACD, Pink Floyd, DSOTM. This is my favorite test CD for new gear and I know it well. This is where I encountered my first issue. I donít know why, but there appears to be a HDMI handshake issue with the 661 and SACD. It would just drop the signal and then pick it up again if I skip tracks. If I just let it play, it does fine. Iím not sure if itís the receiver or my VP, but I donít really care because I rarely use this system for music anyway.

When I had the Marnatz hooked up I could play the track ďTIMEĒ and after all the alarm clock clatter and the track settles down some, I could pin the volume on the Marnantz and the SPL meter would read between 105 and 110 DBís. This is in a pretty small room tooÖ.(12í X 16í X 8.5í) Knowing this, I gave the 661 a spin with the same track. 90 to 96 db is as loud as I could get it to go before it shut itself down. Not bad, not bad at all considering itís only rated at 90 wpc and Yamaha usually overestimates their ratings. The odd thing however is it took out my Belkin battery back up / power conditioner in over load. The Marantz wouldnít ever get the load meter above 70%, at full volume. It would appear this Yamaha is drawing more current as the Marantz. Iíll have to experiment some more with this thing. I ended up plugging the 661 into Belkin power conditioner instead of the battery back up. One other thing is this little feller gets hot!! Wholly crap it getís hot! I can barely hold my hand on the thing. The Marantz wouldnít even get warm. And yes, it's well ventelated.

So after that little test I changed the mains from large to small and gave it a go again. This time I was able to get the room DBís up to 96 Ė 100 dbs before it would shut down. Much betterÖ

As much as I wanted to believe that my Marantz would blow away this ďbudgetĒ receiver in sound quality, I just donít hear it. In direct stereo and pure direct stereo, Iíll be damned if I can tell a difference between the two. The ONLY difference I could tell was the in-between track times when there is no music playing. With the Marantz, there is complete silence. With the 661 I can pick out a very, very slight white noise hisssssÖ. But other than that, it sounds great.

I then popped in the SD / DVD movie Turistas. I started watching this movie last night with the Marantz in the rack and wanted to play a couple scenes again with the 661 to see how it handles LFE in comparison with the Marnantz. I was impressed once again. I think that Audysey has Yamahaís room EQ beat, but the Yamaha is definitely no slouch in this department either. I kept toggling the EQ on and off and prefer it on.

To see how well this unit plays HD audio, I put in the Blue Ray movie Decent. Decent is one of the few disks with a discrete 6.1 channel Uncompressed PCM track on it. Not all HDMI receivers process LPCM multi channel very well and only a small group processes anything over 5.1 channels. Well the 661 processes 6.1 just fine. It doesnít simply matrix into 7.1 either, it recognizes all channels and plays them all. The only 7.1 source that I am aware of is a PS3 game, Resistance Fall of Man. I put this in to test it, and sure enough, all seven channels play. Iím not a gamer, but my kid is. I miraculously survived for a few minutes playing this game and hid in a corner of some building while monsters were shooting at my back. This was way cool to hear. I could tell EXACTLY where the bullets were coming from directly behind me while other monsters were running at me from the sides. Another problem some receivers have with LPCM is when it has a rate above 96 kHz. There arenít many disks out above 48 anyway, but there are a few. Batman Returns is one with 5.1 channel LPCM at 96 kHz. The Yamaha played this just fine, including matrixing the 5.1 into 7.1. Another score for the YamaÖ .

I still have some more tweaking to do, but as of right now, Iím very impressed with this little receiver. For $500, I donít think anyone could go wrong with it. It does better with HDMI audio than many other receivers and Pre/Pros selling for 300% more and upÖ.including my Marantz. I might just keep this in my rack and get rid of the Marantz. I would have to pick up another amp, but for those running 8 ohm speakers in a similar sized room as mine, I suspect this little guy would do just fine.

Iím tired of typing, so if anyone has further questions, fire away. Iím outa things to say.

Thanks for the thorough and brutally honest review, Mike. I was surprised the thing was able to handle the M80s and paralleled-M22 fronts so decently. I wonder how long it would be able to drive them at low 90+dB levels before it went into thermal protection.

I love the honesty in that review.

I'm actually running this older, low end Yamaha 5730 with my M80's, VP150 and QS8's and it runs fine. I paid $120 for it, used. Best $120 I ever spent. It'll keep my speakers running until I move.

After watching a couple flics last night, Iíve found its limit. -10 db on the volume control (range from -80 to +15). With the sub on, this is an average DB of 90 with peaks up to 100. If I bump it up higher than that, it will eventually shut down. And it does exactly that, shut down.

Try as hard as I might, I can not read that without being offended. What kind of an idiot do you take me for? If it was clipping, Iíd have recognized it and reported it. I have nothing to gain or loose here. Nothing. Feel free to go screw yourself.

No, but good idea! Iíll try that and report back.

Well, I think it will be a love / hate relationship. All these damn Scenes and Sound Field options, Iíll go crazy trying to figure them out. But on the other hand, it would appear by speed reading the manual (still havenít really read it), that someone with patience could set up individual Scenes with unique sound fields for every input. Seeing how I only have one input, I doubt Iíll ever use them. But for others, it may be attractive to them.

Set up is very easy. The easiest Iíve seen yet, ever. ButÖ..that also means that this unit does not have all the features one might want. For example, I can not set up the M-channel digital inputs differently than the standard bitstream inputs. If you have an HD player that screws up the LFE channel, you can not fix that with the receiver.

Other than that, I havenít played with it enough to give a detailed opinion.

I think it would be a great Pre/Pro. If I keep it, I will definitely have to get an external amp. I do not like being restricted by wattage and sometimes 100 dbís just isnít enoughÖ

Re: Another Mini Review – Yamaha RX-V661 - 05/19/07 02:56 PM

Hi Mike,

Thanks very much for the great review. I have to admit that I am still very surprised that it shuts down at the level you reported. I wonder if it is shutting down because it is over-heating or because it detects distortion.

By the way, KlipschGuy had a few too many beer in him last night. In another post, he apologized for his posts.

I hope you continue to enjoy your Yamaha.

Re: Another Mini Review – Yamaha RX-V661 - 05/19/07 04:09 PM

I don't see why anyone would be surprised the lower end Yamaha shuts down with the M80s when pushed beyond its limits. Like it has been said before, there is no magic involved, the amps are not robust enough for the job at hand.
Posted by: Mojo

Re: Another Mini Review – Yamaha RX-V661 - 05/19/07 05:53 PM

Well, I am just curious whether it is shutting down due to over-heating or distortion. I suppose Mike can always blow a fan on it and see if it shuts down at the same level as before. If it does, most likely there is a clipping circuit in there that causes the shutdown.

I'm also curious because I have a very low end Denon and I have not been able to get it to shut down with one hour of playing at max (7.1). Of course it doesn't sound good when it's maxed out. And no, I haven't blown my tweeters .

Re: Another Mini Review - Yamaha RX-V661 - 05/19/07 05:55 PM

I was pretty surprised it plays as loud as it does. 100 dbís isnít exactly quiet. In a larger room it will be less, but still not bad.

For reference, I had my Radio Shack digital meter on a tri pod 12í away from the mains and 11í away from the center(s). I had it pointing straight up and I was using PLIIx so all speakers were being used.

Iíll try running the M80ís by themselves next Monday when I have the house to myself. My girlfriend already gives me weird looks, and I might have trouble explaining why Iím listening to music with ear muff on.

If itís shutting down for heat reasons, thereís nothing I can do about it, nor do I want to. Itís on an EQ rack that is open to all sides, and it has 4Ē of air space between it and the next shelf. There is a fresh air supply duct in the EQ closet as well. As I said before, it runs hot to the touch. My Marantz didnít even get warm on the same shelf.

Iím open to do any test you or anyone else would like me to do. I did contemplate moving it upstairs to my two channel rig in the great room where Iím using Rotel Seperates. I have about 4600 cubic feet in that area. But Iím burnt out on routing cables at the moment. That test will have to come later.

Re: Another Mini Review - Yamaha RX-V661 - 05/19/07 06:03 PM

I'm not sure if it would be less in a larger room. My room is twice the size of yours and I achieve 110 dB (C, slow) with peaks higher than that. Maybe it's because my room is very live and yours is more damped...I don't know. It's just occured to me though that my Denon may be cranking out more than your Yamaha. Although my Denon is rated 90W/channel into 8 Ohms, it's also rated 125W/channel into 6 Ohms and 170Wx2 channels into 4 Ohms dynamically.

Holy long reviews mdrew.
Well worth reading though esp. for people who are always looking for a new AVR and like to compare brand x and brand y.

I really don't think it has enough connections though. You clearly need more.

I've actually encountered a similar thing when A/B testing some amps. The 'noise floor' or background hiss is prominent on some far more than others. This was one of the few reasons why i decided against buying the Parasound Halo amps for my setup though Tharkun, somewhat lost now from the forums, had reported he heard no such artifacts with his setup.

Re: Another Mini Review Ė Yamaha RX-V661 - 05/20/07 12:52 PM

I noticed this same noise with all three of my HKís too (7200, 7300, 745). I do not hear it from the Marantz or my Rotel set up. But honestly, other than that and the higher volume / head room, I just canít tell if this cheap Yamaha sounds worse or better than any other receiver Iíve had hooked up. That would be in direct stereo mode, not to be confused with surround modes. For surround, I will have to give the nod to the Marantz and thatís probably due to the Audysey room correction.

I think for the budget minded crowd that buys Axiom speakers would do well with this receiver and any 8 or 6 ohm speaker. The HDMI switching and high def audio processing is as good as it gets right out of the box without needed a firmware fix. I think that is a first for any receiver with HDMI audio processing. Plus, it passes 1080P at all formats without any issue that I can see. And with the pre-outs, it would make a fine pre / pro to go along with the A-1400 (at least thatís what Iím thinking right now)

Re: Another Mini Review – Yamaha RX-V661 - 05/20/07 01:37 PM

Hi Mojo and mdrew,

I suspect it's a thermal sensor that's shutting down the Yamaha when it gets really hot. But it could also be a current sensor into the output stage: when the low impedances of the M80s and paralleled M22s demand more current from the power supply, it senses that and, since it can't supply it, it just shuts down.

As to your Denon, Mojo, it may have a kind of "soft clipping" circuit in its output stage that rounds off the clipped square waveform and lessens the clipping distortion. It's a trick that NAD has used for years on its amplifiers which prevents the amplifier from producing the harsh, edgy distortion of a hard-clipped signal. Don't get me wrong; it's still distorting, but it's not as irritating as it would otherwise be without the soft clipping circuit.

One of the Denon AV receivers that we measured (actually, Tom Cumberland, Axiom's electronic engineer, did the bench tests) at Axiom's lab produced exactly its rated output into 8-ohm loads and the same output into 4-ohm loads. Class A/B amplifiers normally would produce much more output power into 4 ohms than into 8 ohms, so we concluded there was a circuit in the Denon that "clamped" or limited its current flow into a 4-ohm load and even when you turned it up, it wouldn't get louder. So in effect, it was a built-in limiter that prevented the Denon from going into hard clipping when presented with a 4-ohm load.

Of course, although your Denon doesn't shut down, it's still a limiter, preventing the true dynamics possible if you had a much more powerful separate amp.

I know my H/K AV receiver runs out of juice driving my 4-ohm M80s at high concert levels with really dymamic classical music. It doesn't overheat or shut down into 4-ohm loads, but on really dymamic material, the loudest orchestral peaks get a bit edgy and compressed . I think it's likely some kind of soft-clipping circuit in action. Can't wait until I get my own sample of the new Axiom multichannel amp.

Regards,

Re: Another Mini Review – Yamaha RX-V661 - 05/20/07 01:47 PM

Alan,

I suspect you're right about the soft-clipping circuit in the Denon. It certainly sounds distorted when it's cranked to the max but it's not nearly as bad as my old two-channel Yamaha. When the Yamaha was cranked, the sound of saw-toothed waves was unmistakable. I ended up blowing a fuse in my old Bose 601s because of that stunt.
Posted by: alan

Re: Another Mini Review – Yamaha RX-V661 - 05/20/07 01:53 PM

Further to my comments above, our testing of the Denon AV receiver and a few others was during the period when we were considering taking on the Sherwood Newcastle line. The Sherwoods we bench tested did not show the same characteristics when driving the 4-ohm loads. They produced more output power into 4 ohms and didn't current-limit the power-supply stage into low impedances, so long as you didn't drive them beyond their stated limits. This aspect of the Sherwood's amplifiers really impressed us, which is why we decided to carry the line.

Re: Another Mini Review Ė Yamaha RX-V661 - 05/21/07 02:52 PM

Got around to doing some more testing / listening after everyone vacated the house this morning.

I decided to forgo the earmuffs so that I could listen for straining and clipping better. I turned the sub off and set the receiver to pure direct stereo with the M80ís set to large and LFE to the front.

I put DSOTM back in and gave it a whirl. Although this a great sounded CD, it isnít very dynamic, or loud. That being said, I was able to pin the volume on the receiver without it shutting down. Peak DBís were 110. Thatís the positive. The negative is it sounded like crap. Sound quality started to go south at -10 db on the volume control which was an average db of 95 with peaks to 100. After around 95, I could noticeably tell that things just sounded strained, not clear and the mids just lost their slam. As I turned the volume up, it just kept getting worse. I didnít leave it pinned for but a few seconds for fear of long term hearing loss and fear that it was screwing up my drivers. At full volume the average DB was 104 db with this CD. The track I used was ďTimeĒ and I didnít crank it till after all the clocks were done ringing.

After DSOTM, I put in one of my favorite new disks. Carbon Leaf, Indian Summer. I think Mark Johnson would even approve of this disk. Itís mastered well for an Alt Rock type CD. Plus, I just like the music and if Iím going to go deaf listening to something, I want to like it. The second track ďWhat About EverythingĒ has a lot of vocals but also has some pretty dynamic drums and guitar. This track has about an 8 DB range. Not so surprising, it sounded very good till the average db was about 95 with peaks around 103. Clarity and detail just started to fade into a muddled mix of crap and even at this volume; the peaks were starting to loose clarity and slam. I didnít even try to pin the volume with this CD Ė whatís the point? Out of morbid curiosity, I still bumped up the volume to where the average was 105 dbís with peaks around 112. This was at a +5 of a max +15 on the control knob. It did not shut down, but again, I did not leave it there for but a few seconds. At no point during any of this foolery did the speakers go into a hard clip. The music just sounds like crap.

Seeing how my ears were already buzzing, I decided to pop this CD in my two channel rig. This one has a Rotel RB 1080 / RC 1070 comb driving a pair of Wharfdale Opus 2ís in a 32í X 28í space with vaulted 22í ceilings. Ya I know, completely different speakers and electronics, but I was still curious. At about 7/8 volume, even though it was very loud (114 Ė 120 dbs) and it was hard to not wince, sound quality was starting to degrade. I did not try to pin the volume for three reasons 1) sound was degrading 2) it was simply too dam loud 3) my neighbor across the street was giving me a really bizarre look. Now Iím wondering if I need a different amp for this set up another set of M80's because I could pin the volume when I had them in this room.

So for you engineer types, hereís the specs off the Yamaha for you to ponder and speculate over.

Your Yamaha isn't much different than my low-end Denon. Actually, it's dynamic rating is higher than my Denon. You should be pretty happy with it as it provides you with more than enough power.

I wouldn't spend any more money on the 2-channel rig. Save up and buy an EP600 instead .

I am curious how you like the Wharfedales in comparison to the Axioms.

Would this receiver be likely to shut down when powering the 6ohm vp150 and 2 qs8's combined with m60s and ep 500; or could I crank these speakers up to their full potential with this receiver?

T, certainly it's highly likely that the 661(or other similar units)could drive those speakers with no problem. As always, with any amplifier, it depends on how loudly you play it and how wide the dynamic range of the material being played is.
