This is what I wrote a few years ago:

I would assume one would need to spend about 5K to improve upon the internal ethernet connection the Weiss employs, but of course I did not compare any other lower priced streamers and I haven't heard the well regarded Matrix. I do know I did prefer AES over USB from the Antipodes into the Weiss, and I experimented with a T+A DAC 200 for several months, and converting files to DSD 512 using PGGB into its exceptional 1 bit converter, but at the end of the day I preferred the more natural sound of the Weiss 501, even with redbook files, so I sold the T+A and kept the 501. If this was a 1 day comparison I may have kept the T+A, it is impressive sounding.
I have not recently compared ethernet vs. K50 lately into the 501 as the K50 is being used in the main system, and the Weiss is in the office system (via ethernet).
There is only one way to find out the answer to your question
Is there a demo period you can take advantage of?
But make sure you try USB and AES, both with a quality cables, taking into account which the Matrix has or recommends is their best connection, and then what is the quality of your ethernet cable and from which filter, if any? Many variables to take into account to get apples to apples comparing.
