Hello everyone, I figured I would start this thread on the V81 series. I'm very green with receivers, so look forward to learning from everyone. I recently exchanged an onkyo 353 for the v681, and very pleased with my decision.

Impressions so far, the clarity in dialogue is pretty darn good as well as the surround and bass...my budget polk speakers sound quite well. The ypao set up was easy...although I'm not sure if the speaker distances are correct. The only minor gripes I have would have to be the learning curve associated with set up. Connecting to WiFi was a little bit of a pain, but ok. Again this is an owners thread, and look forward to getting the most out of it!

I bought the V481 in July and hate it. It's all mid-range and flat. Wonder if the A series is any better.... Or maybe Denon, Marantz. I use mine mostly for music.:confused:

Oh wow, I don't really notice it being flat as I have it in a small room...I use it mostly for movies and I think it does its job. You weren't able to return it?

Have you attempted fine tuning of the receiver's sound parameters? There are quite a few EQ settings you can mess with. One thing I like about the new receivers is you can create different sound settings for each input; for instance, I like somewhat more bass and highs when I listen to music, but completely different (flatter EQ curve) when watching movies or tv. I noticed that the v481 even keeps different settings for different types of sound depending on what I'm listening through the Roku box; when watching a movie or tv episode it mostly uses the flatter surround settings I've come up with, but music through the Roku uses the PLII music parameters I've set up (highs and bass turned up). Maybe it keys on incoming surround vs. stereo audio. Also, I can set up a completely different EQ curve when listening to music via the receiver's Pandora client vs. its DLNA client input, because my music files seem to sound a lot different from what comes in on Pandora.

I tried to place my front speakers as close to ear height as possible, with the surrounds a bit higher. That seemed to help quite a bit. Also turned up the gain on the sub a little after running ypao, because bass. Tuning sub level in receiver settings didn't seem to make much difference with my speaker setup.

Of course, I'm still playing around with the sound field, and that might take a while. I remember a long time ago I upgraded something and it seemed like it took forever to get things just right, at least to my ears. Drives the wife crazy.

I recently read this somewhere, maybe this forum:

Sound quality is mostly in your speakers and your room's influence, not the electronics.

"Sound quality is mostly in your speakers and your room's influence, not the electronics."

Well, the only thing that has changed is the receiver. The speakers and room's influence are exactly the same.

I should mention that I am using this in a two channel configuration. I had an Onkyo TX-8511 paired with PSB IMAGE 2B's. The sound was MUCH better. This just sounds muddy and flat. Sorry.

As far as the EQ, I tried to play around with it but it didn't sound that much different. I went to: SETUP>SPEAKER>EQ SELECT. Is that what y'all are talking about? If not PLEASE direct me to the right place. I want this to work but as it is there's no way. It is an assault on the ears.

Thanks for the replies. It is much appreciated!

I pretty much have polk budget speakers....that's all the wifey would allow...but my cave is small, so I'm OK with it. As far as different settings for different inputs, does that include stereo as well? And how were you able to apply those settings? Thanks!

I hope your able to find a solution...kinda sucks being disappointed with what you pay for...Im very green with audio...and not bashing my previous bose...but this was a world of a difference for me...just got a lot of learning up to do!

Perhaps I'm missing something, but normally you'd set the AV receiver up for the room by running the YPAO program with the supplied mic. If you haven't done it then try it - the object of it is to correct the response for the characteristics of the room.

Question fellas, after running ypao again, it set my center channel and front speakers to large...I switched all of the to small, and set my crossover to 90...does this about right. I have the Polk budget T series for my 5.1.

Yes, changing to 'small' is often better, since it moves more load to the sub. That's assuming that the sub is in a reasonable position, and that's a subject in itself.

Awesome, my cave is kinda small so my sub placement was kinda limited.

Question guys, my front, center speakers are 6ohm, while my surround are 8ohm...should I set my receiver to 6ohm or 8?

OK I did some research and go figure no consensus...so I'll just leave the receiver at 8ohm!

Different surround mode program settings stick when switching between different audio, even when staying within same input. I thought maybe the receiver keyed on whatever input it was set to, but it's more like it differentiates between different audio modes, even using the same input. I verified this by putting the receiver's surround program settings screen up while using roku plex app to listen to music vs. watching movie with surround audio in the same roku plex app. I set the receiver to output dolby plii surround when listening to the music, then when I play the movie, it switches to straight setting on dsp/surround program option. Go back to music within the Plex app, and it goes back to dolby plii dsp/surround mode. However, adaptive drc and compressed music enhancer settings on same screen do not change with different audio modes.

The compressed music enhancer doesn't function when there is high definition audio or signal over 48khz coming in, so it doesn't matter if that turns on or off automatically. I think the adaptive drc setting should stick with different incoming audio, though. Maybe a question for yamaha support.

Can we get the title of the thread changed so it has full name of the AVRs? Took me a little searching to find this.

Prior amps were HK635 - either didn't sound great or not enough juice to drive my speakers, no HDMI, and weird input issues. It lives on as my massive overkill amp for my PC. Convinced my wife that we NEEDED an AVR with HDMI - just tell her how many wires you get rid of! Then got, for me, a crazy expensive Onkyo NR818 which sounded awesome until the crap wiring at my old rental killed it. Finally decided to a buy a new amp and spend max $500 preferably $400 so I won't be as crushed if it dies. My goal was good sound and as reliable as I could get.

I was planning on the 481 since I have a 5.1 setup, while bi-amping my fronts is a plus but not something that would get me to spend $100 more for the 581. Both concerned me with rated wattage to drive my speakers (yes I know it's mostly BS), I told this to the agent and he offered me a 681 for less than the 581 - that was a no brainer! Should be here next week and I will update with setup ease, impressions, etc.

Just upgraded my RX-V677 to a RX-V681. I like the on board blue tooth and upscale to 4k, and they added a phono input which was lacking on my previous 2 receivers. The only thing I wish as included like my RX-V677 has is an RCA output. I still use a HIFI VCR to record music and since this new unit is lacking that, I will keep my RX-V677 to record audio still. Can't justify the extra $$ for the RX-V781 for the output jacks.
Anyone upgraded the software yet to version: 1.11?
I'll connect it tomorrow and put it though it's paces.

My 681 just showed up yesterday, wow compared to my Onkyo NR818... :( Of course the 818's MSRP was double the 681s so I'm not expecting as much but the thing that struck me is that it has an attached power cable - my last two amps both used IEC plugs. A plus is it weighs exactly half as much as the Onkyo so at least it is easier to pick up :p

Hooked it up this week... sounds decent and it does have enough power to drive my gear which makes me happy. The sound signature seems REALLY weird to me listening to music, if I turn off all processing it is way more bass heavy, almost muddy, vs playback on other devices. As soon as I switch on any processing mode it sounds correct (or at least correct for that mode). :/ No idea what this is about. It does sound nice otherwise.

I am a little pissed that the remote is not universal. For a $600 MSRP AVR that is inexcusable IMO. Yay, now I have 4 remotes again instead of 1.

The AVR is VERY, VERY slow to switch inputs - so slow that it took me about 5 minutes to realize they were working as I flipped between them (I would wait a beat or two, get nothing, move on, rinse & repeat). Not really a major issue but something that is helpful to know, someone using it for the first time may think something is wrong when the input doesn't "turn on".

Don't get me wrong I think this is a decent amp but considering it is one from the top of their "consumer" line I do expect more. If I paid full price I would be disappointed, considering the discount I received I am satisified overall. It does what I need it to do.

Running it as 3.1 bi-amp setup right now, I have two surrounds I will eventually deploy if I can figure out a halfway decent spot. YPAO seems very accurate with measurements btw.

In case anyone is curious my speakers are Wharfedale EVO 30s (F), EVO2 (C), EVO (Surrounds), and a Martin Logan sub. I can definitely make my neighbors cry :D

I ended up switching to the 581, got a good deal for it...still within my budget. Switching inputs on mine is a breeze, have you run an update on yours by any chance?
