There is no difference in sound for a functioning cable, but the cable build quality certainly varies and can cause a fault to develop.
Why do you think that? Posting a link to the cable instead of just a picture is more useful, though
OK, what else did I forget then? I cannot remember everything.
Toslink cables are rather fragile. If you sharply bend such typical cable, you will most probably break it beyond future usefulness.
Ha!
Then again I like cable slack so I can move things around some without worrying about stuff like that, too....but stuffing into/around a sharp corner not a good plan.
They are for sure fairly fragile, but overly stiff optical cables for usage where it is protected (like between a TV and a AVR) is not that convenient either for routing. I don't know whether or not the cable OP linked to is very stiff, though.
Yeah the tech flex may be fairly flexible. I bought some longish USB C cables that have that kind of outer casing, they're a little stiffer but not so bad as some of the heavy HDMI tech flex covered cables I've had (which I've generally gotten rid of).
If it is corroding or possible damaged (pets chewing, pinched by furniture or bending hard around a corner) then you would have a case to replace it. Otherwise, as long as it’s functional, you are fine.
As Van would say, It's Too Late to Stop Now.
