Love my Eversolo A6 Master with TP power supply. I’ve had it for 1 1/2 years and never ever a single issue or hiccup. I do all of the updates and never miss a beat! LOVE the display screen, app, and I think it’s a really sharp, clean looking unit. I am running it to a DENAFRIPS Hermes DDC to a Pontus II 12th…using Qobuz. I see a lot of bad press here regarding Eversolo but I love it. Can’t speak to their customer service because I’ve never had to contact them. Very happy with my unit…
