If you could avoid running any 4 ohm speaker off the receiver,do it. The reason most here don't care for emotiva amps is, they are good for HT,but somewhat lack in the music department. Choice is yours.HT SYSTEM-

Adcom 7500 hands down. Adcom new retail $1500. EMO half that.
Emo specs from their website.
Power output (all channels driven):
300 watts RMS @ 4 ohm (0.1% THD)
200 watts RMS @ 8 ohm (0.1% THD)
THD for the Adcom is less than .01 all channels driven from 20-20khz
I like the way some companies like to rate their power at near clipping:rolleyes:Please. Please contact me a ben62670 @ yahoo.com.

The majority of the time it will be for movies. with occational video games and music. would the emotiva still work.

Can you explain the .1%THD to me

The last Indiana Gathering i went to, we all realized at the same time (though we didn't tell john, because we didn't want to make him cry
) that the Sunfire Grand Signature that he brought sounded EXACTLY LIKE THE XPA-2.
I would bet good money that the two amps are more than just kissing cousins.It's possibile, the MPS-1 was released in early 05 while the Carver unit was first announced in 04 but was never shown until 06, so which came first?....does it really matter? If you have been around long enough you will see many similarities between different company amps as a majority made overseas come from the same small group of manufactures.
The MPS-1 weighed in at 115lbs.

Just some information for the OP to digest. -
THD is Total Harmonic Distortion. The less you have of it the better.
-
The EMO has ten times the distortion at rated power. The EMO would be ok for HT. But why take a real nice set of speakers and drive them with an entry level amp? It would be like putting a four cylinder in a Corvette.Please. Please contact me a ben62670 @ yahoo.com. Make sure to include who you are, and you are from Polk so I don't delete your email.

I don't know why (as a design choice) the Emotiva amps simply don't have a lower THD.
The Parasound HCA 1500 is 0.03% at full power; < 0.01 % typical levels. That is an order of 10 better.
Like dampening factor, some believe that after you hit a certain performance thresh hold your ears can't really discern the difference. -
I am sure the EMO has a lower distortion level at a more realistic level instead of near clipping. Better amps can handle transiants better than others. It is like when you buy a head unit for a car. They rate the silly things at 50x4wpc when in all actuality it is usually 14wpc rms clean. It is a numbers game to get people to jump on higher wattage amps.Please.

Here is a good read on the Adcom. It has separate power supplies like the pic you posted above. It also has twice the Capacitance: 120,000uf verses the EMO's 60,000uF

butter21,
With audio gear, as with most material possessions, you have multiple choices based on cost and performance. Generally speaking, the better the performance, the greater the cost. It's up to each of us to decide the ratio that we are comfortable with. However, when building an audio system, it is best to build it with gear that is at least on the same performance level. As you have chosen some fairly decent speakers, you would want to find an amp that is on the same level. My advice, save up some more money to buy that amp. Rome wasn't built in a day.Political Correctness'.........defined
"A doctrine fostered by a delusional, illogical minority and rabidly promoted by an unscrupulous mainstream media, which holds forth the proposition that it is entirely possible to pick up a t-u-r-d by the clean end."

Are they the same topology? Look at the capacitance of most class D amps. Very little but they still are able to perform. Apples to apples and all that. -
To the OP... also look at Parasound amps while you're at it.SystemLuxman L-590AXII Integrated Amplifier|KEF Reference 1 Loudspeakers|PS Audio Directream Jr|Sansui TU-9900 Tuner|TEAC A-6100 RtR|REL T/9X SE Sub

That i adcom is off the audiogon website.
It's surely not the only one out there - keep looking! -

Well said, Jesse!
butter21 - To reiterate that point, basically, you're attracted to the E...... amps, based on their attractive price point for new gear, but clearly, you didn't use that same logic when buying your speakers, or else you wouldn't own Polk LSis. -

....and he doesn't mean that in a bad way either. What he's trying to say is you decided on some quality speakers, do the same in your decision for an amp. Yeah, I know cost is a factor but quality costs more, should not be news to anyone.HT SYSTEM-

mdaudioguy- At first i was goin to go with the RTi but a deal came around that i couldnt pass up. I like i said before im faily new at this. what should i be looking for in an amp. I dont have a huge budget for this because it went to the speakers. I guess i should done a little more research first. but like i said before it was something i had to jump on. Thanks for all your guys help.

Amps stay in your system a long time. Not the place to save a few bucks. Your speakers should stay with you a while. Sources and processors every few years....what should i be looking for in an amp...
Reread our posts. Use the search function. I am not repeating myself anymore. There have been plenty of suggestions offered up here.Please. Please contact me a ben62670 @ yahoo.com.

The LSi series speakers are nice. Power them with something nice, too. Like Ben said, everything you need to make a good decision precedes this post. Lots of good ideas have been offered. Good luck!

With people comparing a line up of amps to fischer price toys...
Then finding out the Carver and Emotiva are either sharing the same exact chasis or voiced exactly the same....
One shouldn't be so quick to say what's foolish or not.
To the OP: let me google that for you
Enjoy the reading. -
X fisher price is still a toy.
I have heard both amps in house
Do you work for EMO?
2 to 1 guys that have both had both amps in house.
Enjoy
Ben
And the best advise that butter can get is to get BOTH amps in house. Use your own ears, form your own opinions. Most he would be out is the shipping. Simply the cost of curiosity and experimentation.
Hell if Hafler was still in operation I would be running with them, not Adcom. Just a personal preference from comparing DH series to the GFA series in earlier years. -
On the other hand, what's the point of trying out an amp that is, at best, entry level when you have already have speakers that are at a much higher performance level.......pure logic, ya know!?!Political Correctness'.........defined

Those early DH's were great amps for that era,simple and reliable(if built correctly) with good SQ.E Borbely championed the use of MOSFET's long before Mr Pass.Hell if Hafler was still in operation I would be running with them...comparing the DH series to the GFA series in earlier years. -
Your statement is based on personal preferance and not logic at all.
The OP can try the XPA-3 for 30 days and if it is not to his liking, he can return it for the shipping charge.
Many LSi users use Emotiva and are quite happy with the combination. Many LSi users use Adcom and are quite happy with that combination as well.
I own both Adcom and Emotiva and like both products. It is unfair to bash either product.
Hyundai makes good cars, too. Really, they do. They'll even reach the speed limit on the highway, and then some! They have heat, A/C, and a nice radio, too! And for some, they make perfect sense. However, you don't see so many in the garages of $500K+ homes, do you? But, they'll definitely get you from A to B. -

Btw, I'm not pro-Adcom, simply because I have one now. It's one of many options the OP has... E-brand included. A better idea yet, would be to get 25 different amps in house, no?
Basically, people here are trying to open the OP's eyes to the reality that there really are options out there. I was once wowed by the Blue "e", too. The choice is his. Live and learn. Or, learn and live.
Over and out. I've said all I need to say here.
Once again, good luck butter21. Do let us know how it turns out for you! -

Because that XPA-2 at $800 may be a Sunfire Grand Cinema at multiple times the price. You would have to ask Concealer and the guys at that GTG since they a/b'd them and couldn't tell the audible difference. -

Who cares? Some think the OP should buy an Emotiva amp, while others think he should look at used amps that once sold for more money. It's his choice - all the opinions are out there.nooshinjohn wrote: »That was a prototype Carver that was abandoned when Carver Corp failed. It was then picked up by the guy that started Emo.... -

I own Adcom, I own Parasound I am happy to say I am pro-both. What I am not is anti-Emotiva.
I couldn't hear enough of a difference between the XPA-3 and the NAD C272 to make me, SQ wise, pick one over the other. The NAD was a little warmer in the mids (desinged this way on purpose) and the XPA was nice and neutral the entire spectrum. One wasn't any worse than the other. Just slight shades of gray. -
My opinion to the OP.....there are some nice old Carvers on e-bay right now...I've had good luck with mine...and I could simply detonate my monitors if I wanted to..."Making life enjoyable through expensive electronics." BillD
