TOSLINK OPTICAL cables

A good glass fiber toslink will have more resolution than standard monofilimant.  Recommendations are Lifatec or something like Wire World Supernova.

But in general, a good COAX cable will be better than toslink.

Interesting. Most say fiber optic better 

I go with polished glass. Not much more money. Never fails no matter the length. 

+1 for Wireworld Supernova...
