I recently sold my pair of AMC2445 for an LPA-1. The AMC2445 were setup as 90wpc x 3 (L/R/C) and 45wpc (RR/RL).
The difference in the upgrade was immediately apparent. Although the AMC2445 was a HUGE upgrade over a receiver; the upgrade to the LPA-1 was a nice step up.
The biggest differences were the imaging of my speakers. The AMC amps just couldn't bring these speakers to create a nice stereo image. As soon as I used the LPA-1, the speakers opened up a bit more, sounded more natural in movies. The center channel benefited the most - the voices of the people in the movies just 'sounded' a lot more like the actual voices they represtented. In cars - Owen Wilson's voice was unmistakable.
The amc amps while very 'musical' they also sounded a bit harsh. The Emotiva amp got rid of both, and instead of everything being 'musical' - only the musical music sounded musical. The highs were much less abrasive and more coherent.
Overall, I really like this amp - and will hold onto it as long as I can before upgraditis kicks in and an XPA-5 comes wooing me away
It just sounded even more like a real movie theater - all I need now is more popcorn!

I've now had some more play time with this amp. I've also taken time to redo my EQ settings in Vista for room correction, which helped considerably - highly recommend some kind of room correction if you've got it - use it!
Music - 2.0 > Diamond 9.1's
REM - Losing my religion
While I love this song for the simple fact that it's just a classic. The AMC amps sounds more sterile, while the LPA-1 was more full bodied. The AMC amps had a tint of thinness in the sound despite only powering bookshelfs. The LPA-1 again dominated in pure imaging - I have to double check the center channel is off because the voices are coming dead center. The AMC's wouldn't do that.
Clarity - the signal was just coming through the speakers clearer. I could hear quieter background noises with less strain.
The added Bass became immediately apparent when I played Norah Jones feat. Peter Malick group - New York City; a track I downlaoded from hdtracks.com (very nice) in Flac.
The begninning of the track gave so much more bass and authority over the speaker that I had to confirm the sub was off. When I turned the sub on - it only went a bit deeper; but it was shocking just how much power was making it's way to these speakers.
The LPA-1 just keeps the signal nuetral, I'm not hearing an amp as much as I'm hearing what my speakers should sound like.
Movies - 5.1 Spiderwick Chronicles
With the proper EQ dialed in, I can't take the volume past 20% without making the wife upset. The sound is clear, I hear all the footsteps clearly. All of those lovely noises that previously hid themselves in the background are now clear as a bell.
During dialog scenes just hearing the actors taking breaths between lines.
The LPA-1 was a winner, and the UPA-7 I'm sure is a winner as well.
