Ah, you didn't mention what player you have. If you have an Oppo 105 or 205, then it would be much better to use the Oppo to "play the SACD" and output pure analog using the 5.1/7.1 RCA analog outputs to your receiver. Much better than sending SACD over HDMI and having the receiver decode/DAC the SACD data.

For digital COAX, my standard "low cost" recommendation is the Beldon 1694A from Blue Jean Cable. Make sure you get a minimum 6 foot cable (even though you don't need it). A digital cable that is too short will have signal reflections back to the transmitter and cause errors in the square waveform pulses. The 1694A is $20 plus shipping for an ultra cheap solution that I have found beats a lot of other cables.

For a big step up, I would recommend the DH Labs D-750 digital COAX. Solid-core silver plated conductor (which is what you want for digital transmission). A 2 meter cable is typically around $225 or so, unless you can find one used.

Or you can look at some of the Audioquest cables in between.
