Duke (or others),
I would be grateful if you would "editorialize" just a bit more about matching an Atma-Sphere S-30 with Quad ESL 57s. I have a Stokes-restored pair of Quads and a fully-balanced Joule Electra preamp. I would love to try this amp, but some seem to recommend the more powerful M-60s instead. Not sure if this is for power or impedance reasons. Also, are the Speltz autoformers necessary (or strongly recommended) to run Quads with the S-30 (or the M-60s for that matter)? Thanks for any input.
