There is some similarity in the design of the Stasis series and the original current dumping Quad 405. Both involve using a small high quality amp directly connected to the outputs of a larger current source. The Stasis 3 uses a class A front end amp with a cascoded AB output stage using 16 matched output devices per channel. Consequently, it employs no protection circuitry and uses a much larger power supply than the Quad. Weighing 50 lbs, it is built like a tank.Sound? Short answer: perhaps a touch lean in the lower midrange but very smooth. Exceptionally clean at the top. Can drive very difficult loads such as the reactive environment of electrostats where I used mine for many years. It does not, however, clip gracefully. It will sound brittle if you push it too hard. Mine has been utterly reliable for 26 years. Although it was not experiencing any problems, I decided to replace the power supply caps about six months ago.
I have some scans of the product brochure and schematic if you are interested. Send me an email and I'll send those to you.
