I have had the Eversolo DMP A6 since its release. It replaced a Sonore optical rendu with linear power. I have very good Revel speakers, all vintage tube electronics. Internet is all fiber. The A6 streams to a Okto Stereo 8 via USB. Firmware is currently updated on the A6 and the Okto. The A6 has, since its arrival, sounded bright and digital. Oddly enough, I am spending more time listening to Radio Paradise (FLAC) streaming via my Roku Ultra/Oppo 205 than via the A6. The Oppo sounds really good playing Redbook CD's, fantastic playing SACD's via the Oppo's HDMI outputs. The A6 is the weakest link in my setup.
Proposed solutions: adding Roon; the Beatchnik linear power upgrade for the A6; trying a new dedicated streamer.
