Heres my slightly long round-up:
First of all, the show was organized pretty well. Static demos + the demo rooms were well marked and the flow was very pleasant. Cons- which are an occupational hazard, I suppose, were that the rooms were small and close together, with high noise floors and lots of bass leaking through, especially for those unfortunate enough to be near HT demos, with explosions going off every 5 seconds. I gravitated to the expensive rooms, of course

and didnt bother with the multichannel rooms for the most part.
Magico/Devialet: What most people were looking forward to, I think. The Audire guys were very friendly, and had an audiophile CD to give away for free. The Devialet looks gorgeous, especially mounted on a wood wall. The fake wall, however, caused some room issues, in my opinion. They also had very cute wooden cable risers, which I wanted immediately. The sound was- well, ok, especially on one choral male vocal track, where the imaging was pinpoint. Very laid back, though, and not very engaging. The tracklist was also the usual audiophile dreck- female vocals et al, but maybe thats just me.
Ascendo/Playback Designs/Ayre: This was nicer, somehow, and the Ascendos are very striking to look at. Nice separation, although the tweeters were firing past me in the nearfield configuration in which theyd set these up (Apparently, thats how they are supposed to be. Rearfiring tweeter, maybe?) Also, these had no bass, which is weird for a big ported sub. Sandeep from Audire was also very friendly- thumbs up. The front end gear was super of course- you cant get much better than Playback Designs.
PSB- Ive heard this at the Mumbai store many times, so didnt spend much time here. I dont know why the Synchronys dont get more audiophile love- superb measurements, warm, dry, room tunable bass. For the price, theyre fantastic.
Martin Logan/Peachtree Audio: They had the cheaper Logans, so there was the usual discontinuity between bass and midrange. Super airy sound, though, especially considering how close to the back wall they were. Made my miss my Maggies, and wonder why I had let them go! The Peachtree Audio gear looks very nice, btw, and the Norstone stands also looked very cool, in an understated Scandinavian sort of way.
Sonus Faber/Nuforce/PS Audio: Burge was very nice this time; he normally looks very busy

. I loved the bookshelves- the best bang for the buck at the show (92k), although the anaconda sized cabling they were connected to probably cost more than the speakers.

They also had a supercool mini-Rack of Silence type rack, which Burge said was for 20k, and their other room (GoldenEar) said was for 75k, so Im not sure what was going on. The mini Nuforce looks very tempting. The PS Audio music server they had music streaming from had a very nice UI- this is usually my bugbear with those sorts of devices, but this one was very clean and intuitive.
JM Focal: There were literally 70 thousand people in the room when I went, so I didnt bother going in.
Legacy/Parasound/WireWorld: This was a beast of a setup. Ribbon tweeter, ribbon mid, MTM 8 mids, and 2 12 woofers actively amped with 1000wpc ICEpower modules, into an active room correction module, into Parasound monoblocks, with a sub as big as my apartment to further improve (!!) the low end. It was way too loud, however, and there was some fatigue after a point, with excessive detail, in a hammer the point in sort of way. They demoed it using this ultra boring drum track, that Ive now heard at 4 different demo rooms, I think. Give it a break, guys

This was the only setup to accurately play both my torture test discs, however, so Ill have to give it Best Sound of Show for me. Its a slightly unfair comparison, though, because they did have room correction, but its part of the system they sell, so why not?
Test discs:
Gordian Knot- Arsis (solo fretless bass).

This has lots of open E string work, which most systems struggle to reproduce, without either farting out or going into boomy, one note bass mode.
Pat Metheny Group- The Way Up.

This has lots of layered instruments, which are a killer to image properly (vibraphone, synth, guitar, marimba, drums, guitar, trumpet, overdubbed several times). Plus, right in the beginning, there is a car horn, which should correctly be reproduced around 4feet wide of the left speaker. The Legacy got this spot on.
