Ok, so it took me forever to respond, but the deal is this: The Yamaha SACD player that I own doesn't seem to have output by either optical or co-axial. For the meantime, I used my heavy duty Cayin CD player for an optical transfer to the Yamaha MCX1000. Absolutely perfect, so mission accomplished, since I tend to like the Cayin(tube output, except of course for optical/coax).
