You're probably not doing anything wrong. You're just being honest with what you experienced.

I'm sure if you were to post this result, those same people are going to tell you the amp is defective or that you are doing something wrong. That adding a big external amp should really let your speakers "open up" or "lift the veil"or any other number of colorful descriptions that have no scientific backing or basis.

If you were not at the limits of your AVR's internal amps then adding an external amp will not make an audible difference.

Haha.
I received an XPA-5 in the mail a few days ago. I have it plugged into my system and have been listening to various sources to test it out. It's good! I don't hear a whole lot of difference between the XPA-5, my NAD 275's and my Sunfire, however, adding the Emotiva improved the system as a whole. I now have 9.2 amps and subwoofers. I am going to wait for the 2016 models to replace the AVR with another AVR or Pre-pro.

I feel a little like Meatloaf in Paradise by the Dashboard Lights. The 2015 models are saying "do you love me; will you love meforever?" I'm saying I'm not sure, I think I may have to wait another year. Ok, Meatloaf didn't say that. I did.

Keep the XPA-5 in the loop for a week or two to get used to it, then plug the speakers back into the 708. Does the sound seem anemic, or missing "something".

Haha, DUC got there. I will add to the "open up" comment above to qualify my response/thought.
I have 3x Polk Rti A9 LCR(running in full range), with RTi A3 front uppers, and FXi 6 surrounds that used to run on an Onkyo TX NR 808, then ran with the 808 and XPA-3 in a 19' x20' shared space with the movie area being ~11.5'x19'. When I added the XPA-3, the lower/lower mid range became more audible and clear. I don't have a calibrated microphone to prove it, but it was clear as day difference. That receiver has since been retired with a bad HDMI board and replaced by an Denon 4520CL. However, I am more than willing to test it out if anyone in update NY has the receiver and a mic to do so. If there are no measureable results, I will eat my words and shut up in the future.

I've had my XPR-5 for over a year hooked up to Salon2s, run full range at reference and they do not sound any different when I switch back to my Denon AVR. No anemic or something missing sounds. The only thing missing are the pretty dancing lights I see on my XPR-5. Maybe I've just gone tone deaf.

You are right though. Since he already had the amp, there's no harm in giving it a couple weeks. He just needs to make sure that he's level matched as closely as possible when making the comparison.

Sorry, I updated my post. Just trying to help is all, I have not been able to delve into the world of waterfall graphs and tangible results yet. Next theatre...

I made measurements on my system and while there were some differences, they were negligible and not audible. The differences could easily have been ambient transient noises.

The hard drive on my laptop I used for REW has since died and been rebuilt. I no longer have the measurements of my system. I actually had quite a few measurements on the testing of external amps vs. an AVR, speaker burn-in, bi-wiring, passive (fool's) bi-amping, etc.

Your 708 has plenty of juice to drive those speakers, unless you're trying to achieve reference levels, and that's where the external amp comes into play. If your are listening at -15 below refernce or below, most likely your avr has the power you need. You can do some research to be sure - take the distance your MLP is from your speakers and your desired listening levels, and plug it into an online amp calculator like Crown has at their site (link below), and it will give you an idea of the power you need. Amps are a good investment, as they give you the headroom you need for peaks, and they give you great peace of mind. As far as improved sound quality, well you've already experienced how that works.

That's whats great about this hobby, we all have different opinions and experiences, and ears and rooms lol, I know I don't have the best ears in the world but one of the biggest improvements to date was adding two UPA-1 amps to my Yamaha Receiver, all volume levels sounded just straight up clearer and more dynamic, but that's my ears and my room, and speakers and room make a big difference as well, if you want better SQ add some acoustic treatments

Can't wait until I fit full 128 speaker ATMOS, then buy three XPR-1's for each speaker, each speaker triamped.

All plugged into one mains strip lol

Bwaahaahaaa...
Please let me know when so I can purchase a share or two in your parent electric company.

I shouldn't laugh though, my final tally will actually be 3 - XPA-5's and 2 XPR-1's....
(And that's if I use an AVR and not a Pre/Pro)

*Warning* None of my suggestions, ideas or even thoughts have any WAF, in any way!

Congrats! Let me know how it goes. I receive mine this Friday. My new stand to accompany the XPA-3 arrives today. I plan on having it all assembled and ready for the XPA-3!

I know you did not say this, but I am wondering if there is a break-in period for an XPA-5. I mean after it runs for awhile, it starts firing on all cylinders so to speak and sounds different. Even though I have only had the amp for a few days, I can tell already that I would miss it if I took it off line. Because I added the SPA-5, I am now using NAD 275's for surround and surround back which provides a nice balance.

The XPA-5 is driving the front (Klipsch Cornwalls) and center speakers (2 Klipsch Heresies). I don't know how the Klipsches compare to other speakers, but I think they are fairly efficient, so the Emotiva does not have to work hard to drive them. Anyhow the XPA-5 sounds good to me. If there is a break-in period after which it "burns-in" and sounds better, then WOW.

Pure conjecture here: This being my first amp, my guess/inclination would be not beyond the first time few times it was turned on which was most likely done at the factory. Solder or other subtraits might need a chance to break in like a computer processor before you overclock it...??? Others can probably answer more definatively...

The only thing breaking in is the listener's perceptions.

A well constructed amp's performance is not going to become unleashed with any break-in shenanigans. Depending on the class of amplifier like tubes or straight class A those amps will benefit from a bit of a warm up period but beyond that nope.

If your prior form of amplification was of decent quality and you never really taxed it, then you will not hear a lick of difference between it and the XPA. What it will afford you is peace of mind in that no distortion or compression from the amp will likely to occur with aggressively loud passages. Unless of course you have an extremely large room with really inefficient speakers then you will definitely hear improved dynamics and less fatigue.

CPUs do not need a break-in period either before OCing, just make sure cooling is correct and progressively step up the settings till it is no longer stable then back off.

Best regards,
