Mike,
Your thoughts so far are similar to mine. I'll have to visit the Volti room again.
You must visit the Wilson room at the Hyatt. The XLFs with the Thor Hammers are super impressive. They are playing a good variety of music including some yet to be release DSD music engineered by Dave Wilson. The front end is DCS Davinci played through VTL and wires by Transparent. This is a treat.
Jeff Rowland's gear is in a number of rooms. I spoke with him yesterday. Told me that he uses Revel Salons to voice his equipment (did you hear that Mark?). The 625, 725 as well as the new 825 and 925 look great. The 825 is at the Lawrence Audio and Joseph Audio rooms making some pretty nice music.
The Wilson Alexias are sounding very nice with Doshi. Best I've heard them sound. No, I have not heard them with ARC or DAG.
Crowds and demos are smaller than last year but still a great show to visit.
