My wife and I were there on Friday (no way was I going to get her to go all 3 days). I thought the Pure Audio Project Duets in various forms were all quite good. The Altecs were amazing as were the Perlistens.
one demo I found fascinating was RD Acoustics demo of their EVO3 isolation pucks under a streamer/DAC. They were playing a number of different tunes and all were much better with the pucks under the DAC. The sound difference was not subtle. On a Phil Collins tune in particular the sound with the pucks was much denser, clearer, more articulate, improved attack and decay, and more air. I couldn’t really get into a location to properly hear the soundstage attributes, but others in the room were quite impressed. I’ll be ordering a set of these to experiment in my rig.
