I nominate Museatex. It was designed by Ed Meitner, advancing from his earlier eponymous brand, and the new company failed despite glowing reviews. I scored a "demo" system used by a former sales rep: the Power Amp, Line Preamp and FM Tuner, for about 10% of retail; then I found the Phono Preamp on ebay, again for 10% of MSRP — it's the best phono pre I've heard
People say it's "tubelike" but that's so misleading. It's just highly musical, and endlessly satisfying, in all genres, with my current speakers.
