Just posting to introduce myself and show my support for the project!
I just installed Volumio yesterday after finally getting my RPi. Some trouble with mounting the ReadyNAS, but after a while I sorted it out and now it’s working great!
I’m using a Cambridge DacMagic Plus USB dac, and unfortunately I experience some pops and cracks. But it’s perfectly listenable up to 24/192 FLAC files, so hopefully the playback will be as good as perfect after trying out all the fixes or maybe with the next update. I’m using the Pi as source for some decent equipment, so hopefully it will good enough as an audiophile source.
