I have no way of motivating pricier optical cables to myself. In a traditional electric cable there can be all kinds of leakage or disturbance, hums, hiss and so on, but in an optical cable the light reaches the end of the cable - or it doesn't. It is a digital signal, there are only 1 and 0 as possible results, nothing in between. So I see no advantage in gold connectors, quadruple insulation or anything such.
Yet this one feels a bit more "premium" than the kind of toslinks that are included with your equipment, which - I must admit - feels nice. I guess we are all gearheads in one way or another, and having something that feels slightly "better" at least makes me feel better, even though I cannot really say that the product is better.
But at a low price this is a good purchase, no matter how you look at things!
