Chinese emigré educated in America. In-demand member of the Paris diamond exchange and its first supplier of diamond jewelry to the Carrefour Group. Guitar session player with instruments of his own design. Expert of precious metal alloys and their acoustical properties. Dark horse of audio whose acoustic resonators at first met applause and ridicule in equal measure. Applause came from highly satisfied customers; ridicule from those who refused to attend his demonstrations but invoked existing theories to 'prove' how these devices couldn't possibly work as claimed...

Resourceful. Intuitive. Prepared to fail. Relentlessly curious. Driven. Energetic and independent. Impossible is not a term that should be in the vocabulary of any real inventor...

Philosophy
Air is the carrier of sound waves. If not hermetically sealed off by air locks, all the rooms, nooks, crannies and closets in a house including the refrigerator, oven and all furniture with doors communicate with each through the air. Traditional heavy damping can absorb excess acoustic energies. But such damping also tends to kill off the finest harmonics, dumbs down the performers' tone modulations and dries out harmonic textures. Overdamping further undermines the swing of free timing. If one addresses air disturbances directly (primary causes are the loudspeakers and how they interact with a room's geometry), the quality of sound propagating through the air improves automatically. This is a direct cause/effect result and our acoustic resonator technology strategically exploits it.
