Hopefully there's a coaxial and/or optical input in addition to USB.

There does appear to be some kind of processing or filtering opertion. I'd like to see a digital implementation of a crossfeed circuit.

I'm also hoping there's a digital output, so that I can connect a pair of DSP3100s for a killer desktop system.

G68, G91, G98, DSP3100C, DSP3100 (x6), M80 (x3)
