Interesting to read these comments and makes me wonder if I am getting the most out of my Bricasti M3 (Mdx card). I have always used it with the ethernet connection which I think is excellent. My experience has been very different than that of @audphile1 as I believe what I hear is the opposite of "dull, rounded off and not engaging". I have also seen lots of reviews indicating that the Mdx ethernet input on all Bricastis is very good and not lacking relative to the other inputs.
Nevertheless, I do wonder if I am missing something. @audiotroy how did you connect from the Aeon to the Bricasti? USB? I had been toying with the idea of moving up to the M21 or possibly the new M11 (ladder DAC from the M21), but maybe I would be better off focusing on a dedicated streamer?
Please note, I do have a good server (Sonicorbiter i9) connected to a Sonore OM deluxe, so I believe that I am feeding the M3 a very clean ethernet signal.
