TOSLINK OPTICAL cables


simple question....is there an audible difference in the quality of these cables?  Recommendation?

I go with polished glass. Not much more money. Never fails no matter the length. 
I hooked up my CD transport and compared good coax to inexpensive Toslink, then switched back and forth to try to hear a difference. I cannot say I heard one. Others will have different views, I’m sure, but what I’d like to learn is why different optical cable technologies *could* matter?

Junk the POS cheap plastic toslink cables that are comparative crap performers and move up to a quality glass fibre model. The audio performance difference is huge.

I have both the WIREWORLD SUPERNOVA 7 and the DH LABS Silver Sonic Glass Master Toslink for my TVs. Both are great performers with a nod to the WIREWORLD as my #1 choice in my experience.
