You are mixing things. On one hand, cable, especially data cable is designed to a spec. to carry 192khz/24bit means certain data transfer capacity. different cables might have different data transfer capacity, due to which standard they comfort. asking which cable to get is a genuine question (you need HDMI 2.1 cables to transfer 8K video, for example)Cables....
However I read in the forum often people discussing about the possibility (or not) of transmission of 192khz/24bit music over toslink, for instance in the wiim mini thread. Some people claim it depends on the quality of the cable. Would it be worth testing a few of those in order to have a sort of buying guide?
if data transfer capacity is not a concern (all micro usb cable is capable of 480mbps), claiming a cable reduces noise etc. is a warning sign of snake oil
