I read many good things about Volumio, and I am currently using OSMC. I am trying to go a bit “hifi” (got a yamaha s501 stereo amp, a B&W CM5 pair of speakers, a turntable) but I would still want to continue using the PI as music source.
I wondered a lot about this: would there be any quality difference between OSMC and Volumio when playing music (say .flac) on the same hardware? (RPI 3 + DIGI+ -> optically connected to the AMP). Because I need OSMC for movies etc, and in order to use Volumio I would either need a second RPI or a dual boot configuration, both options having some downsides. For me I would expect that there wouldn’t be an (audible) difference when digital output is used, but I don’t know much about how OSMC and Volumio are doing this.
