already tried altering speaker positions and room treatments. mayb will try the risk free 30 days trial. can it drive 6 ohms speakers? thanks for your help Brian.

Yes it can drive 6 ohms; it is rated at 4 ohms.

Emotiva has a web site that includes specs and test results.
post #1563 of 1944

The XPA amps are rated for 4 ohms loads, so 6 would be no problem.  My question is, what volume is your AVR set at when you notice the sound issue?  A room that is 15 x 15 would have limitations that might be affecting things, depending on how loud you are running at.

 

I looked it up and your Pioneer is THX Ultra rated.  That speaks to higher class amplification and I'm familiar with this because my Onkyo has the same rating, and it doesn't run out of steam as easily as a mid level avr.  The reviewer was pretty impressed with the Pioneer room correction, that was my next possible issue.  Were you satisfied that the set up ran correctly and the results were good?

 

Other than that, it is possible that you are running out of steam and a separate amp can certainly help there. I actually added an Outlaw 125 watts x 7 to my Onkyo, which has the same wattage output as your SC 57 and the improvement was noticeable, though my issues weren't volume related.  I'd think though that the XPA-5 would be a good place to make an improvement if my above suggestions aren't a cause of your issues.

yes it will drive them easily...

remember I had the EXACT speaker setup as you although I had bookshelf mains (but still 6ohm) I have a feeling the xpa5 is what your looking for..

No worries on that, we're pushing 4 ohm speakers here without breaking a sweat.

All,
I am a proud owner of a Denon-AVR4311, Aperion Verus Grand Towers, Center and Bookshelves for surrounds and a Seaton Submersive.

I recently upgraded my receiver from an Onkyo TX-NR1007 so that I don't have to switch cables while occasionally watching a 3D movie with my kids on my 115" screen.

In spite of the rave reviews I read about the AVR-4311, I feel the sound coming out of my speakers is not as crisp and lively as it did with the Onkyo. I have run the Audyssey calibration at least 3 times and followed all the guidelines in AVS and things haven't improved much. My Denon produces very powerful sound but the high frequency sounds seem to be a bit muffled, almost like you have a couple of "thin" blankets over your ears or the speakers.

I do not have a dedicated man cave. Instead my Den / family room doubles as my HT room. My couch is against the back wall hence I can't take any measurements behind the listening position and the 2nd issue is that my Family Room / Kitchen combo has a wide opening to the rest of my 3000 sq ft home.

Will adding an Emotiva XPA-5 help me in any way ? There seems to be an equal divide in people's opinion about the benefits of an External power Amp. Some swear by it and some say it won't make a darn difference when one already has efficient speakers and powerful receiver as the AVR-4311. I do like to crank it up once in a while and I have heard a little bit of distortion when I try to show off my setup to my guests.

Can you please steer me in the right direction ?
Note: I have pm'ed many of you and asked the same question. Thank you for your feedback. I am still positing my concern here to get additional responses and seek input from AVR-4311 owners.
TIA,
Cheers,
Raj

the volume level will be at -10db when i start hearing the harshness. i think u r right it could be my 15'x15' room. also im going to try lowering down the channel level for each speaker,maybe i put the db level too high for each individual speakers. after the mcacc setup(mic setup) i pushed each speaker level quite high.
i don't think emotiva will let me have the 30 days trial cause I'm not staying in the US. i might just take the plunge and get one anyway. will do more research and see.
tks audio4life.

Raj,

I had an Onkyo 886 prepro that I replaced with a 4311. I found the SQ compared quite well with the 886 and did not find the high end to be muffled at all. Although I'm using the 4311 as a prepro with a Boston Acoustics A7200 amp. I listen to a lot of 5.1 music (SACDs and DVD-As) and I'm very happy with the SQ. You could try the XPA-5 to see if it will help. I would think the XT32 of the 4311 would do a better job of calibrating your system over XT with the 1007.

Have you tried listening to music in Direct to bypass Audyssey? You could also try the Audyssey Flat setting to see if that sounds better especially with music. I've been using the Flat setting for quite awhile and prefer it over the standard setting. I'm not well versed in all the settings of Audyssey but could there be a setting that is active and effecting the hi end? Also you could look through the 4311 manual and check all the settings that could possibly effect SQ especially the high end.

I am pretty sure if the Audyssey mode is on "Movie" it rolls off the high end

It sounds like you prefer the volume to be quite loud.  After setting mcacc I would assume you found the volume range too low which is why you would make adjustments after the fact.  You may actually be pushing the Pioneer past what it can safely do, I would be careful about damaging your speakers.  And yes, I would think the XPA-5 would help you in this case.

Thank you for your input Bill and Brian. Your assessment is on the right track. I am pretty happy with the way Hollywood movies sound but it is the music that is lacking the high frequency response. Besides, 25% of Bollywood movie content are music videos and there too I feel that the upper frequencies are lacking.

Bill: I have played around a bit with Audyssey disabled. Unfortunately, that turns off Dynamic EQ as well and without Dynamic EQ music sounds lifeless at low to moderate volumes.

Is there a way for the AVR-4311 to automatically select a different Audyssey curve based on source material (Audyssey for Multi Channel sources and Flat for stereo sources) ? if not, can i change the curve by pressing one button instead of going through the Menu options ?

Using the "MultEQ" button on the 4311's remote you can toggle through Off > Audyssey > Audyssey Byp.L/R > Audyssey Flat > Manual EQ. All this information is on page 89 of the 4311 manual. So you can change it on the fly for the type of listening you are doing.

Bill
post #1574 of 1944
Thanks again Bill. I remember messing with that button while engaging Dynamic Volume in complete darkness. Not sure how many more cents it would have cost Denon to provide a backlight for those buttons. Anyway, glad to know the target curve can be changed on the fly.
I have another issue with my setup. I have a Denon AVR-1912 for my backyard speakers and passive sub in the same media cabinet that has the AVR-4311 (side by side ... 10" apart). As you can imagine the remote commands for one wrecks havoc for the other. However, only time I use both setups at the same time
is during parties. At other times I can carefully turn ON one and not worry about the other. However, for whatever strange reason, selecting a new input from the remote sends a Turn On command automatically and turns on the other receiver.
Is there any way to disable the Power On command linked to the Source selection buttons ? I couldn't find any information on macros linked to the source select buttons on the remote.
Can anyone shed some light on this issue ?

Cheers.

i dont usually listen at -10db but just did some test at that level and was curious. Today I lower down the channel level for each speaker and it sounded much cleaner. The levels were to high, now I can hear more detail and better dynamics. Hope my speakers not damage. How can u tell wether the speaker is damage?
post #1576 of 1944

If your speakers sound fine at the lower levels, then you should be fine.  Nice that you were able to get things sorted out!

speakers sound fine. Just had to lower down the channel level and now sounds better. Correct me if I'm wrong but since my speakers r 6 ohms its pulling more wattage from the avr. Sc-57 is rated at 190w/c at 6 ohms roughly estimated, so I don't need to push the channel level to high also considering that my room is small.
I did run the mcacc setup again today and didn't adjust the channel level of each individual speakers at all. Now I'm very happy with the sound.
Tks again audio4life

just hooked up my new gen 2 xpa-5 to an yamaha reciver and ran calibration and it's reporting all but one speaker needs to be reversed. Any thoughts why this might happen? I just flipped the positive negative and re-ran the calibration and it looks ok, Odd that it would need to be out of phase?

If you are sure the way you had it before is correct and everything has been validated, I would put them back the way it was and ignore the calibration. You need to validate that the internal speaker wiring is correct as well. Sometimes room acoustics will cause strange anomalies like that which you can ignore.

Thanks, It looks like it's some type of bug in the new version of the reciver firmware. So I switched the connects back to what they should be and just ignore YPAO.

I agree with the some of the others are saying. I'm not a big fan of Audyssey for music. I would turn it off and go from there.
post #1582 of 1944
Now that I have my xpa-5 hooked up I hear a hum from the speaker when I am with in a foot of them. The receiver is on but not play anything. Is this normal or some kind of ground loop sound? If i remove the connection between the receiver and amp I don't hear a hum but static instead.

good article about trouble shooting ground loop hum. See if any the tips work for you.

make sure there are no power sources near the amp.

I was doing some rearranging the other day..and there was no hum...but every time i pushed the console back in place a hum that was never there before happened...I was sooo frustrated...

I finally pinned it down to the mcbook pro power box (little white power box) was getting pushed close to the amp..introducing the hum.

hope this anecdote helps

Used to own an XPA-5, while it was a good amp I sold it for that very reason, static audible at about 1 meter with no input. No ground loop problem, but I attributed the static to the high 32dB gain of the amp, maybe a little OCD but I couldn't stand it so dumped it for a used Adcom that has a much lower noise floor/no static.

Uh, he said "hum", not static. Static when connection removed, not a problem for him. As an aside, I do not have loud static from my Emotiva amps in my system, barely any even with my ear to the tweeter. May be differences in other components (including speakers) and/or my older ears, natch.

Pretty sure I saw "static" in there, regardless his XPA-5 is a gen 2 and I believe the gen 2's have less gain so maybe there is another issue, but my experience with my XPA-5 still stands.

post #1589 of 1944
I also had a hum / buzz issue with my XPA-5 gen. 1. See my thread (includes a solution): http://www.avsforum.com/t/1481773/emotiva-xpa-5-and-umc-200-both-have-issues

This amp is prone to these kinds of issues due to the buildup. Should be less audible though with a gen. 2 because of the lowered gain.
post #1590 of 1944

I have an Emotiva XPA-3 and three UPA-2s. All of them are totally silent when connected to my Onkyo 5009 prepro and powered up, even with my ear close to the speakers (M&K S150s).
