DVD/SACD with coax digital input?

Running a music first multichannel setup with the all-analog Audio refinement pre-5 preamp. Sounds great, but I have no way of decoding my digital cable 5.1. Is there a dvd player, preferaby with sacd that has a digital in so that it can convert an external signal to 5.1 analog?
I am totally unaware of any playback devices currently that have a coax input to DAC an external source.
