"That's a familiar sight—and a familiar sound." When I walked into On A Higher Note's large room on the Denver Tech Center Marriott's mezzanine floor, the speakers being demmed were the Vivid B1s that I review in the October issue. I loved the sound of the $14,990/pair B1s in my room and they were doing equally sterling duty at RMAF, driven by a Luxman M600A amplifier ($8500) and a modified Revox open-reel recorder. A 15ips tape of a cello, piano, and double bass playing what sounded like a tango by Astor Piazolla, recorded in LA's Disney Hall by Yarlung Records, had an ease to its sound that allowed the music to flow. The room had a touch too much bloom in the upper bass—perhaps the Synergistic "magic bowl" you can see on the post on the wall behind the speakers was fatigued after a long day adjusting the room acoustics.
