I heard a Spectral/MIT/Avalon Eidelon system at Progressive Audio in Columbus, Ohio, and it was definitely the best system I have ever heard. Granted, I have only heard the Avalons once before, but the Spectral electronics seemed to be far more neutral, quick and balanced than the Krell electronics that I have also heard with the Avalons. If I could afford Spectral electronics, I would buy them myself, but you just can't replace one item at a time with Spectral. Since their amps, wires and preamps require the correct matching components, I guess I'll have to wait a few years. Oh, well...
