A few months late and a different model than you were asking about, but I've been using an Outlaw 770 amp with my Ascends for about a week now.

As I'm using my old receiver (Denon 4802R) as the pre-amp, I didn't expect a huge difference, but I'm pleased with the difference I am hearing. The bottom end is just much more solid, making up for some of the limitations in my HT room (hard wood floors, rugs aren't an option due to a couple of very annoying cats who piss on anything left on the floor...but anyway...)

I've also noticed a few sounds in songs that I swear weren't there before. I was having a bit of a problem with a ground loop hum when I first hooked everything up. After isolating and removing the problem, I put on some music and during one song this strange buzz popped up again. At first I was really annoyed, then I noticed it was a quiet bagpipe that I'd never heard in the song, but it was listed in the liner notes.

Getting into the more esoteric, "complex" music (classical, prog) seems to sound "better" than before. That might just be the better low end, but there seems to be something more to it. If I were a true audiophile, I'd probably throw out a half dozen terms that mean jack, but "better" works for me...

For movies, again the bottom end is a bit more pronounced, and I'm of the opinion that dialog in movies is a bit clearer than before.

On the negative side, my wife doesn't like the way the 770 looks. While she actually prefers the Ascends to other speakers (she thinks wood veneer looks cheesy), the 770 is a "huge black box with a glowing green light". When I first got the Ascends, she immediately mentioned how good they sounded, but with the 770, she just keeps staring at it...Fortunately, I get to keep my toys if I like 'em, since I let her keep the cats.
