i stumbled on information about Volumio somewhere online- it sounded really interesting. i had a Raspberry Pi lying around, so i decided to give it a try. after a bit of a struggle, Volumio was up and running. i tested various styles of music, in various formats: ogg, mp3 and flac. all played back flawlessly and sounded great. (initial tests were through the analog output.)
i am currently using a usb Muse Mini DAC on the R Pi, through a Technics class h amp. EXCELLENT.
best to the volumio team/community…
also- here are some instructions on how to add SomaFM streams to Volumio…
