I've been following this thread for a few days. For those who either want more digital inputs and/or want to conver optical to coax or vice versa here is a product I use with great advantage into one of my 990's inputs
MSB Digital Director They claim it reduces jitter as well, though I don't know if I have it or not. It has priority auto-switching. There are four optical and two coax inputs. It has coax and optical outs.
They can be found from time to time on Audiogon and ebay.
