Years ago, at a San Francisco Audiophile Society gathering, I was lucky enough to spend time with the late, brilliant electrical engineer
Roger Modjeski, whose
Music Reference RM-200 Mk.II hybrid stereo tube amp is among my most prized hi-fi treasures. I asked him what he knew about transimpedance phono preamplifiers. He grabbed a piece of paper and a pencil and drew a detailed transimpedance phono preamp circuit, quipping, "These have been around forever, but until recently no one has paid much attention to them."
