I've got a Dynaco St70 running my Quads. I've had the amp wired in triode put gold plated rca's and had 5 way binding posts added. It also has a tube preheater installed. I run the amp with a Dynaco pas 3. I have a Krell,Classe,Avi monblocks, and Opera Consonance M8oo monoblocks. The Dynaco is still my favourite. It puts out about 12 watts a channel. By the way i've never ran anything but tubes on the Quads. After 50 years they still have the best midrange of any speaker made. One last comment. The m800 i also run them in triode at 35 watts per channel and they sound sublime.
