Stereophile does a much better job of remembering David Hafler's history than I could here, although they pass on how he popularized the "ultralinear" tube circuit:( http://stereophile.com/news/11661/ ). Bill Johnson single-handedly resurrected tubes( with the SP-2 & 3 preamps/D-150 amp), after SS had blown them in the weeds during the sixties, and spawned an industry that is embraced by all those of us that love the sound of live music. He and Jim Winey teamed up back then and sold Johnson's pieces, demo-ing them with Magneplanars as a system. About the time that Audio Research gear became more widely distributed, and Jon Dahlquist released the DQ-10, The first time-aligned/matched & free standing driver(all but the woofer) speaker system in production: John Curl designed the JC-2 which was probably the first piece of High-end" gear ever: a little negative feedback to reduce the IM distortion that plagued SS, pure class A push-pull, a separate board for moving-coil cartridges, and an outrageous(for the times) price of $1050.00. The piece sounded so good for the day: it forced tube designers to make their equipment sound better. We have all benefitted from the designs of these men, and the strivings for better sound that their designs started. AND ABSOLUTLY: It all started with Thomas Alva Edison, and the machine he actually intended just to take dictation!!! Is that what you had in mind Nrenter? I agree- the background does make the nomination more interesting.
