Sharing a Hilton ballroom with Legacy and AVM, the Austrian Ayon tube amplification was being demmed with Lumenwhite Artisan speakers ($40k/pair). Source was the new Ayon Music Server and two-box preamp. Listening to Pink Floyd's "Another Brick in the Wall," I thought the sound was better than it had any right to be given the suboptimal acoustics. Then I spotted some of the Synergistic ART Acoustic bowls on the wallsmy left brain knows these silly little bowls can have no audible effect on room acoustics in the audio range; my right brain was busy telling my feet to tap!
I don't believe Legacy and AVM were using the ART Acoustic bowls in their half of the ballroomthat system's sound on the same Pink Floyd track didn't have the focus and coherence that it did on the Ayon/Lumenwhite system.
