Im going to go out on a limb here and guess that it would not be easy enough to warrant the cost and effort involved. You would have to basically add decoders for any sound format you wanted it to be able to process (DD, DTS, TrueHD, DTSHD, etc....) and DACs to feed the Audyssey stuff. What would the benefit of having digital inputs/outputs on it anyway? Its designed to insert easily between pre/pro and amplifier. Just curious. I am really impressed with Audyssey and what it does when used correctly. It really does what it claims and does it well.
