Glass v.s. Plastic Toslink


Is there a real difference in the sound quality between a plastic and a glass Toslink cable used on your Apple computer running into a DAC?

The glass Toslink that I have seen are around $60 for a meter v.s. $10 for plastic.

I'm fine trying the $60 glass. Are there glass cables cheaper than that; who sells them?
Looked on Amazon; not finding glass Toslink. Found this on Lifatec:

I don't have the money to buy the gear I want, so I do a ton of research instead, and Lifatec has the best deal on glass toslink that I have seen.
