i bought a used one, but it was busted, and confirmed as such by paul at pro digital. you can see the light on the output end but it is not passing signal either way. i got my money back for the cable, thankfully, and i have to return it to the seller
paul at pro-dig said they no longer make the sony cable, but there are a few old stock that already have the mini optical out built in. he said he can still get them for $85 (?)
i was contemplating getting a new cable, but if this rs optical dealie works for you, i may give it a whirl
