I went on Friday also. The Koa finish is way cool.
I definitely heard a difference between the AudioTechnology and Eton midranges. (I think the Eton and Accuton are more alike than different, the Audio Technology is definitely more laid back).
I thought both the main room Jim was on and the room up on 7 with the BeAT sounded good given the rooms. Really, two of the best rooms I was in all day. The room on 7 with the BeAT, had a guy pushing some small squares of crystals that "really opened up the room, couldn't I tell how much better it sounded?".... I smiled and chatted him up (though held back on saying... well I have a suspicion that it's the speakers but hey, who knows if you can sell cards with crystals more power to you).
I was really bummed out in the Jolida/Black Ice room as Jim's speakers looked great, but in my opinion the room was a disaster all day. I tried going 3 times. The first hour of the show they had that ridiculous black-ice eq 4 channel thing running so hot it was distracting. The second time I went back it was turned down a bit, but between way too many chairs in the room, with 4 big speakers it was just insane. The guys working the room were constantly fidgeting with equipment and it was just difficult to even get a listen. The Encores looked awesome though, and the third time I was in I did get about 30 seconds of listening before a person stood in front of one of the speakers for a good 2 minutes before I got up and left. In those 30 seconds... I was impressed! (though still found that 4 channel thing distracting).
