I am now retired, a UNIX user since 1983, but no LINUX expert by any stretch. 4 days of Volumio experience and having fun with tinkering and listening.
My first system with Volumio, Pi, usb DAC, and TPA3116 amp is up and running on a table top. Now I just have to get it all into 2 cases and enjoy.
I am very impressed with Volumio, the rate of ongoing improvement, and the community involvement.
