I picked up this item since I use my PC as a lossless music server and use a outboard DAC for processing.Unless you need to use a optical connection, this item is not needed. Just go out and purchase a gold plated RCA to 1/8" adapter and throw it on the end of your coax cable. You'll also be cleaning up the signal path.
