Potential to use a even more high end D/A (digital to analog) converter than the one built into the empeg, or direkt into an amplifier with digital inputs (hopefully containing a good D/A) lessening/eliminating problems with induced noise in RCA-cables and or ground loop noise as digital sigals are less susceptible to noise (or rather, easier to reshape back to original shape/interpret correctly even though there's some noise)
