I thought Bricasti’s room (with Tidal speakers) at AXPONA was one of the very best. They played real music, not audiophile demos; the room was set up with care and acoustic treatment; and the volume level was realistic, not earsplitting. Tonal balance and timbre reproduction were excellent. A respite from the many rooms with loud, booming, systems.
P.S. Now that I can afford Sound Labs, I no longer have room for them. Oh, well....
