Those look like digital cables. You should be using audio cables for hooking up multichannel SACD.

So not sure how that will affect the sound or if it will at all...

Basically it's a question of how much signal loss and/or crosstalk you might get with them.

But for $35 or so for the set, not much to lose I suppose...well other than $35.

I'd still play it safe and get the Bluejeans cables, but that's just me.
