Wait, what? So we would need to somehow get the signal converted to S/PDIF without losing resolution if we wanted full resolution of, for example, our HDTracks and Linn records purchases (and needledrops)? I think Monkey's question wasn't really answered -- if my understanding was correct, the amp does the crossover, the correction, and EQ, but the controls are in the computer, so the computer "tells" the JH3A what to do, and then you can disconnect it. Not sure if the JH3A has any controls on it at all. Is this still the case? Looking at the JH3A page(s), it looks like it has digitally controlled volume and bass boost controls.
