I know for the most part, a cable is a cable, no matter what the price tag or the so called "quality" of the cable is said to be, and that you wont see an ounce of difference between a $200 HDMI Cable (For instance) between a $20 HDMI cable. Although, I am fairly new to the whole high quality sound system scene, and I was wondering if the same thing applies with optical cables? Will I be just as good with any old cable rather then spending $50 on something useless? Also, what are some optical cables you guys would suggest? Thanks.
