I have an "older" (6922-based voltage stage instead of the SN7's used in phild's) Elliott-modified SA-100 (designated the NP100) with a Plitron toroidal transformer. It employs a bipolar SS output stage.
I've written an extensive review of the unit, reproduced on Mike's Web site at www.altavistaaudio.com/testimonials.html. To summarize, it's "sweet," dynamic, and near-holographic, given appropriate source material. When I wrote the review, I had Symdex Epsilon dynamic floorstanders, but now drive a pair of Magnepan 1.6QR's in a 26'x14'3"x7'8" room up to approximately 90db levels at my listening position 10 feet ahead of the Maggies. If the NP100 (a rated 100-watter at 8 ohms, 140 at the 1.6's rated 4 ohms) is clipping, I can't hear it. Most of my listening is to classical, with a fair amount of jazz, all played on a Sony SCD-777ES. The preamp is also an Elliott-modified unit, a Counterpoint SA-2000 tubed line stage.
I second phild's suggestion to contact Mike directly.
Hope this is helpful.
