Agreed that the Soundscapes were a highlight of the show. Jim was also most kind to let me linger a little after closing time to listen further, since I had to hit the road last night. Yes they will require some serious power. IIRC, they were being driven by a 330 watts/channel AVA amp. Great sound.
Other highlights were the Audio Note speakers, Harbeths, and Fritz speakers.
Blown away by what Fritz's speakers offered for the money. That room was really dialed in with bpape's treatments, and sounded mighty good.
