I needed to run toslink optical cable about 10 feet and I had two 6 foot cables lying around. So I bought an optical cable joiner that I plugged one end of each cable into, and presto chango I had a 12 foot optical cable that seems to work fine. But my question is this: is there any reason not to do this? I figured that since the data is all digital there was no possibility that this could hurt the sound. Is that correct?
