There is a very obvious limitation in case of USB: cable length 5m max.
A nuisance at the home occasionally, prohibitive in a studio.
With Ethernet you don't have this problem.
You can reduce the amount of analog cable substantially by replacing them by a single CAT cable.
Cost and flexibility is where AES67 style protocol is about.
At the home I do think the network solution (streaming) is by far the most popular in market share be it DLNA or Airplay.

Hi,

Not really.
There are many possible solutions to the length limit. When AMR made a music servers for our dealers and distributors (not for retail sale, strictly to help them demo our USB input equipped CD-Players and DAC's) from generic touch-screen PC Hardware, we included a 20m active USB cable with the setup.
As I said before, there is no silver bullet in Firewire, Ethernet, USB, SPDIF, AES-EBU or Wifi for transmitting digital audio. Each one carries challenges, limitations and compromises and needs to be implemented well, with a view to what matters in Audio.

At 20 bits, you are on the verge of dynamic range covering fly-farts-at-20-feet to untolerable pain. Really, what more could we need?
Are POWERED USB Extensions not allowed?
Bad? Good?
Too much is never enough
There are excellent solutions:

As long as you talk master-slave it will do but it remains peer to peer.
You always have to run a dedicated wire.
A LAN is far more flexible

This is exactly correct. No amount of techno blather can change the reality of where the market is going.
