First post! AVSforum rocks, tons of good info... Anyways, I was planning to take a trip to Radio Shack to get an optical audio cable for my new Audio system. I was wondering whether brands and models matter for these cables? If so, what are your favorites? Does it really make a difference to get really expensive cables? (I'm not exactly and audiophile, just want to utilize my optical input enought to get good quality sound)
