Ethernet or USB for Streaming

Hello, thanks for responding and Happy Holidays!

I have a question and am seeking opinions. I have a Cambridge Audio AZURE 851N Streamer/DAC and currently have a Studio subscription to QOBUZ. I can stream to the Cambridge either through the Cambridge Stream Magic Android App that uses the Ethernet connection, or I can stream from my PC using the Cambridge USB driver. Both methods can play back 24/192. My question is which connection is technically better? The Ethernet connect is a quality 10' CAT7 cable plugged directly into the back of my Gateway and a high quality USB cable plugged directly into the back of my PC/Server, the cable is 2 meters in length. When I listen and compare the two connection options, they sound slightly different but am a bit confused as to which one is better?  Your thoughts would greatly be appreciated.

Thanks

Follow your own ears first.

My general advice is that Router (Gateway, in your case) direct to the Cambridge should be superior to your PC / USB chain.

Adding a LAN isolator between the Router and the Cambridge will help tremendously. A hospital grade isolator is a good place to start.

This recommendation is from Kevalin Audio:

I have not used it, as of this time.

Going with a "medical grade" isolator will cost more, but offers better performance.

There are a number of "audiophile" isolators and filters available...cost is generally higher.

Perhaps others can offer suggestions based their experience.
