Awesome read and mandatory for all digital audio users!

Also an interesting point I saw in a review of the Gen 2 Antipodes DX made by the DX designer:
According our man in New Zealand the argument against Ethernet (and for USB) runs like this: compared to Ethernet, USB has the potential to carry more noise from the server to the DAC but generates less of its own noise inside the DAC (think: receiver chips). Ethernet remains a good strategy with a noisy server. However, it can be bested by USB when a low noise server with a decent clock is present.
My fist experience with an Ethernet Renderer in a DAC has not been overwhelmingly positive. I feel that it ads a whole new series of variables that we (read I) am unfamiliar with: linear power supplies for Ethernet switches, low voltage switches, audiophile grade Ethernet cables, direct connection with bridged Ethernet ports vs. using a switch, etc.... there are a few excellent threads that discuss these tweaks but it all comes down to how crazy into the computer end of the DIY you want to go versus embracing a ready made server product.
Do I think that Ethernet Renderers built into DAC's is the best big thing? YES, I do! Do I think everyone is ready for it and the audio world is prepared to implement it properly? No,
