Well, just the basic facts, I think. I have seen one or two web pages where people mentioned modifications to it. What would the improvements be, exactly? I was mainly wondering what the basic specs were. Like S/N ratio (it almost seems to me to be passive, so would this even apply?), the stereo channel separation (dB), distortion (%), and also the relative quality of the pots/wiring/electrical components. I know nothing about this unit and it intrigues me because it sounds so good and appears to be built so well. It would be cool to know what flavors of equipment with which it performs best. I have it hooked up to a Myryad CD player and a McIntosh MC-2205 and it sounds preeeetty good. Thanks very much, Jason.
