In some sense, it doesn't surprise me that there's some market for this. For the older audiophile who doesn't understand digital music or networking, their only analog is.. analog. :-) So if you look at the setup with "vinyl goggles", where upgrading your stylus or pre-amp or cartridge _does_ have some impact to audio quality - since the physical diamond or sound chambre can vary - you can see how someone without any IT knowledge could conclude that, likewise, upgrading the devices in the "signal path" (network) for digital music would make an impact. Now like, obviously that's wrong, but if someone is willing to pay you $2000 for a Realtek switch in a fancy case.. Clearly the market will oblige!
