In asking about connecting my Yamaha CDX-710U CD Player I thought it had an optical output along with the regular rca analogs but checked again and it has a single rca digital out not an optical. Question: will using the digital out to my NAD T752 allow the NAD's DAT to convert instead of the CD player's since the DAT in the NAD will be much better then the 11 year old Yamaha's DAT??
