Three channel must have been a big thing in the early 60's. Sunnysal wrote he remembered vintage Macs having a center outputs and Fisher made tube receivers, amps, and integrated with center outs. The X1000 has a separate volume control for the center channel. I would be interested in reading 'The Hobbit' articles. When I lived in Mississippi I had a friend named 'The Hobbit'or 'T.H.'for short.
