As you've probably seen from his profile at Georgia Tech's website, Professor W. Marshall Leach, Jr., is a highly distinguished academician in the field of electrical engineering. Around 1980 he had his own company, "LSR&D, Inc." which manufactured The Leach Superamp monoblock amplifiers ($1598 per pair, at that time), and also a lesser stereo model.
They were reviewed by Peter Aczel in "The Audio Critic" vol. 2 no. 3, Spring through Fall, 1980. That was well before Mr. Aczel went over to the dark side and adopted the belief that all amplifiers meeting certain basic criteria sound the same. He named the Superamp "the best-sounding high-powered amplifier tested so far, regardless of price."
If you wish, contact me through Audiogon and I'll email to you a scan of the review.
