As always, I read these comments and discover I somehow missed a bunch of stuff I would have wanted to hear. Damn.
My favorite rooms:
Bricasti, with their M1 DAC and new monoblock amps, plus Tidal speakers. This was the sound I liked most at the show.
Devore Fidelity, showing the new Gibbon X and the O96. Wonderful.
Horning speakers in the High Water Sound room. Plus, Jeff Catalano is a really compelling guy.
Sadurni Acoustics horn speakers with the Merrill Veritas amps and International Phonograph tapes as source. Not exactly neutral, but perhaps the most gorgeous, luscious sound I recall ever hearing.
Tip of my cap to KEF. Their demo was the LS50s and the Blades, both driven by PrimaLuna electronics, showing that you don't have to spend a fortune to get high-end sound. I'll bet this demo yields a lot of LS50 sales, a few Blades and probably some PrimaLuna also.
