[Dane] built this excellent home theater pre-amplifier. He used [Mark Hennesy]‘s pre-amp design to start with, and added selectable XLR, RCA, SPDIF and even USB audio inputs. Discrete inputs from his DVD player provide surround input, and an analog matrix creates 7.1 surround from the 5.1 input. The design is very elegant, and even uses a VFD display that appears blue with some filters. I usually just buy my HT gear, but projects like this make me seriously consider re-building my entire HT from scratch.
