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.
