Hi,

Yes that's it, it might sound a little better than SPDIF, but most likely given the source is a C15, it won't make much difference if any, but it's worth an experiment.

IMHO to really improve the AQ from a C15 you should consider adding a network connected Sooloos Endpoint. There's been lots of discussions on their relative merits in other topics. Try Google Searching the forum and post any follow up question in one of those topics.

Regards,
Carl
