I am wrong in thinking that ethernet is opto-isolated? If that assumption is correct, I assume this negates any electrical effects that a switch could have on interference (ignoring UTP differential pairs and assuming that this is never an issue anyway)? And I assume this switch isn't doing some absolutely insane decoding of some common unencrypted audio protocols to 'improve' audio in any way. As everyone else has already said... what an insane money-grabbing audiophile-abusing product :D

Base-T ethernet is magnetically isolated (transformers), not optically isolated. AFAIK those transformers are generally good for on the order of a few thousand volts of isolation. So they'll fix common ground loops, but I wouldn't rely on them to protect against worst case lightning strikes. For that you want fiber (eg 1000Base-SX), which is intrinsically opto isolated. And yes, most anything from the "audiophile" world on the digital side is hokum - the entire point of digital technology is all-or-nothing error correction. At least it's easy to ignore, unlike having to sift through all the harder-to-falsify hokum in reviews when shopping for analog gear.

  Ah! Thank you for that :) I will have a read - I wonder what interface I was thinking of ¯\_(⊙︿⊙)_/¯ > And yes, most anything from the "audiophile" world on the digital side is hokum - the entire point of digital technology is all-or-nothing error correction.

Ethernet usually has magnetic isolation through tiny transformers (oftentimes included inside the ethernet PHY IC) to avoid any issues with different ground potentials and such.
