Selah, yes. I did not stay long and really had no impression to relate.
I recall seeing Salk also but same deal, sorry. I only had a few hours and a lot of ground to cover.
The systems that caught my ear that I spent time listening to were the one pictured above, the Cathedfral speakers, the room demoing Magico V3 and comparable YG aCOUSTICS, AND United Audio with their mbl and RTR setup (which was good but not set up as well as their showroom), and the little Jolida integrated running the Nola monitors, which was the best sound value of the show that I could see.
The Polk audio room was the only one that did not sound good to me in some way. They were going for the overpowering bass deal which turned me right off.
