Just an observation. Many of you know I was chasing the digital dragon for a few months and I'm pretty happy with where I am now for the $$$ invested. Eversolo DMP A-6 with upgraded LPS, Supra Excalibur USB and Merason DAC1 Mk2. I have a TP-LINK and a portable Archer battery power supply for it. On a whim yesterday I tried inserting a 12 inch CAT8 cable from the TP-LINK to the Eversolo because Ive never been sure if my Eversolo was connecting to the TP-LINK or to my Main Router which is in the same room and very powerful. Plugged in the Ethernet cable to listen for an audible difference and whoa!!! Started going through reference tracks. Noticeably blacker background and even more detail. More textures and warmth. Maybe my Eversolo was not connecting to my TP link all along? I am not tech savvy so I have no idea how to check. But the ethernet connection is a clear winner here. Big improvement and NO cost!! Ymmv.
