There is a difference in optical toslinks cables if your downstream system is good enough to reveal it.
15 years ago I went on a toslink merry go round and settled on the Lifatec cables posted above. They sounded best. This was when using them between a CD transport and DAC.
That setup is long gone, and I recently needed one between TV and DAC. I got another Lifatec. OK. Then I got the QED Reference Optical

This was a noticable upgrade over the Lifatec. It even surprised me how much better it was, considering it has less strands of glass than the Lifatec, and it's on TV/Xbox duties only
There is a few other botique optical cables out there. DHL Labs and Wireworld to name some I have not tried.
