This is ridiculous. Andy, you're insane. Fanboy? If on this planet there was ever a fanboy its your love affair with Rhythmik.
Oh yeah? Wanna bet? Wanna fight? My amp's inaudible crosstalk and thd is more inaudible than yours... My amp can kick your amps ass.... Oh yeah? You drag your 85 lb amp over here and I'll prove it to you. I am ntrain, a legend in my own mind.......
I give up.
AND I sent you that pm because that guy was looking to buy a UPA-7 which you have for sale. See, I'm trying to be nice to you even though you are a royal pain in everyone's *bleep*... :-)

Hey now Monkuman, don't make fun of my furry ears. XPA-2's are a great amp for those who feel the need to compensate for other short comings. ;D As far as awesome, refined sound, Mono-blocks Rule!!!! lol Well I am 5'6".. ;D But like LOTR said, I am a genius so listen to me. Actually, there is no right answer to this question between an XPA-2 or a pair of UPA-1's and there are merits to the OPINIONS being shared. That's what makes it a fun hobby, to try things to see for ourselves. Even though the XPA-2 is better.

lol, not the short coming I was referring too but . . . . :-)
I totally agree Monku, the XPA-2 is the better amp choice (for the hearing impaired) lol
OP, just order 'em both and send your least favorite back. It's such a tough call between the two as both amps have their strong points over the other. It just comes down to personal preference. But the UPA-1 is better. :-)
Oh, and also buy the DH Labs Signature Speaker cables now on Audiogon for $248 cause they rock. I consider them "Budget Reference" cables. :-)

Its in my sig Andrew. Snell C/V. I'm sure you will say they suck too.....:-) OK, thanks for answering that. So your speakers feature a SILK DOME TWEETER with significantly less on and off axis amplitude response which have a much more laid back sound compared to the Revel's which feature a metal dome tweeter which have a higher frequency response range coupled with significantly higher amplitude both on and off axis. Heck if Im right, those Snells also have a good chunk of foam on the front baffle board to help reduce and absorb high frequency reflections as well. In your case the higher THD of the XPA-2 is going to be reduced in amplitude just due to the fact alone of the tweeter design and set up. Even the sensitivity of those Snells require double the power roughly to get the same output volume as the Revel's here in question. So your basing your experience on a speaker totally different in nature to the Revel Towers the OP has just picked up. The Revel's are going to reveal more of the amps characteristics and potential deficiencies in the treble range. ANd thats one big reason why I especially recommend he go with the UPA-1's because of the significantly lower high frequency THD. And again if the OP, is dead set on more power which would be absolutely and literally useless to those Revel's, then I'd recommend the XPA-1 monoblocks. He will have literally limitless headroom(well technically 4db over the UPA-1), perfect channel seperation/0 crosstalk and retain a very low THD in the treble range(which is IMO the most important thing for those speakers).

Just got my Revel F12's today and holy &*^% they're freaking amazing. But my Carver M 1.0t MK II crapped out on me and I need a new amp for the fronts. Note: The carver went bad before i got the speakers. I'm using a different Carver amp right now for the Revel's The dealer i got them from told me to not exceed 200 watts. Will a XPA-2 be to much, since it's rated at 300? The XPA-2 would be fine... Having too much power is never an issue... Speakers don't just blow up... You'll hear the speakers struggling (and likely damage your hearing) long before they blow... As for the UPA-1 versus XPA-2 debate: either would be fine for the Revels... I can't help but laugh every-time I see that debate on these forums... If you want lower power and refinement, then I would suggest skipping Emotiva amps and getting some low powered tube or even SS amps from any of a zillion other manufacturers... Emo's advantage is producing high powered SS at ridiculously low prices... For the $800 I paid for my XPA-2, I could have purchased an endless number of low powered amps, but where else would I find a good quality 300 watt beast???

I don't know why ntrain keeps hammering on how "bad" the THD of the XPA-2 is. Yes, it is higher than the UPA-1, but it is so low that not even a dog could hear it. ;D I just took a look at the Audio Precision test results for an 8 Ohm load. Any guess what it shows? Let me save you some time. The XPA-2 has THD of 0.02%, or less, from 2 watts thru 200 watts per channel with both channels driven from 20 Hz to 20 KHz. The Revel F12 speakers will probably never approach drawing 200 watts at any frequency level, let alone those in the treble range. The differences in room acoustics will have a far greater impact on the smoothness of treble response than any difference between the UPA-1 and the XPA-2. Get real, no human being will ever discern a 0.02% distortion level. Depending on what the OP's intended usage of the amps, I can make an argument for either one of these amps being better than the other. There are many more important variables involved here than the near non-existence THD. I sincerely believe the OP will be extremely impressed with either one of these amps. Any audible difference between the sound of these two amps will be minor, assuming the supporting gear even allows the difference to be detected. If you are looking for the optimum refinement in your sound buy the UPA-1; AND, if you are looking for the maximum impact in your sound buy the XPA-2.

I just reread this entire thread! ...I just luv it! ;D Here's where I'm at now (if it still counts)! In order of best combination of amp(s) to go with your Revel Concerta F12 loudspeakers, "mon tres cher" Kraemerkid: #1 > @ www.bryston.com/4bsst_m.html ...But $$$ ...Best amp though! #2 > A pair of Emotiva XPA-1 monoblocks. #3 > A pair of Emotiva UPA-1 monoblocks. #4 > An Emotiva XPA-2. #5 > Four options is good enough! ;D *** Me, in my own situation, with my own bank account, and with those Concerta F12s, I'd go with option #3. ;D ___________________________________ And NOBODY else here from this thread (by the way I luv you all equally guys ;D ) influenced my final suggestion. BUT, I truly appreciate EVERYONE's (without exception) input. Bobby

Ha, Cali Samarai. . . .you just keep your sword to yourself!!! my cables cost too much for you to be hackin' on!!! Go hack on RR's Emotiva cables! :-P
John Belushi was the bomb though! I bet he would have chose the UPA-1 over the XPA-2 !!!

I bet he would have chose the UPA-1 over the XPA-2 !!! Yes, he probably would have if he were staying in the role of when he played Beethoven in one of his skits. Because Beethoven was deaf. ;D (note to the OP - sorry we sort of made your thread skid off course)

Beethoven was a musical genius so naturally he would have chose the UPA-1 for his music. I'm sure he would have like the XPA-2, at least as a step stool since it's taller and heavy. BTW, what the heck is this "Schiit Asgard" on you equipment list. Are you now making up stuff just to look cool. I mean, what's this "Schiit" ??
