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? Interesting discussion here: https://arstechnica.com/civis/viewtopic.php?t=648269

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.

Something like this is very good no need to spend hundreds of dollars on an optical cable. To answer your question no you will most likely not hear any differences between optical cables unless they are broken.

I have definitely heard differences between a low cost plastic monofilament toslink and a Lifatec glass fiber toslink.  I have heard differences between both toslink types and various COAX cables.  It really depends on your ears and the resolution of your audio equipment.
