As far as I know its just a Ethernet cable and that means that there would be no difference to the "sound".
It does have an extremely high bandwidth at 100 gbps (gigabits) but unless you have a audio file that requires 10 gigabytes per second then it is completely useless (Uncompressed audio is at most a few hundred kbps).
Also the pure silver and other features would not make a difference to sound quality.
So I would say go buy a $5 Ethernet cable as the audio is digital and the receiver will either get the packet or not, the cable can't damage the sound quality unless it's analog.

Please don't believe even this (technically sounding) claim! You cannot specify the "bandwidth" of a cable, so even if they'd write 2Tbit/10km it would be just as made up as what they are writing now.
What you can do is to specify physical parameters, such as attenuation at specific (most interesting: high) frequencies, distortion and reflection caused by impedance mismatches at the connectors. Then maybe it will meet the requirements to transport Ethernet accodring to the standard, and under the conditions specified therein (1000Base-T, IEEE 802.3ab), carrying 1 GBit/second over up to 100 meters.
And while the cable being sold might be well shielded enough, and using a dielectric that allows it to exceed the attenuation requirement of Gigabit Ethernet by huge amounts, 100 GBit/s is so far off the scale that I'm pretty convinced that with current technology this is completely unattainable, even under best laboratory conditions.
It's worth noting that the 100GigE standards only allow copper cabling up to 7m (or 30m at a push). Despite the advert's claims, 100m is fibre-only at this point.
