The press conference that I personally found the most exciting on the Show's first day was by Ralph Glasgal (left) on his Ambiophonics system. I knew about Ambiophonics (a signal-processing system designed to cancel out interference between a pair of loudspeakers, creating something akin to binaural listening but from speakers instead of headphones), but somehow I’ve never heard a demonstration, or at least not a convincing one. The demo setup at HE2007 was rather unusual, with a pair of giant Sound-Lab electrostatics at one end of the room, and another pair of floor-standing TacT speakers at the other end, the setup intended to demonstrate how the system works with these two types of speakers. I only heard the demo with the Sound-Labs, but I must say I was quite blown away with the huge soundstage, precision of imaging, and sheer ease of the sound. The Ambiophonic processing was performed by the latest TacT RCS 2.2 XP ($6000) which also functions as a full-feature preamp, a digital room correction device, and a D/A converter. Tact’s President and Designer, Radomir Bozovic (right), was also on hand to answer questions about the Tact system.
