Very cool. I was very interested when the IEEE Spectrum original feature was published, and got one of the Tripath amplifiers to play with. It was a commercial product, marketed as inexpensive toy. Then people on Head-Fi Forums started taking these things further. One of the forum members started modding home-theater amplifiers, so I purchased one and it was great. Vinnie Rossi, Red Wine Audio. It is still amazing. But his stuff is now quite out of my price range. These amplifiers are great fun, though.
