I am using volumio with an Allo USBridge and the Tidal plugin (which costs extra). There are the usual hiccups you would expect from an early-stage, open-source product. In particular, during setup it took time to solve an issue with distortion. However, now that is up and running, I really enjoy it. The sound is genuinely great, it works well with Tidal once you figure out the volumio interface, and the only niggle is that you have to reboot and/or lose connection from volumio to my home network at least once every 3-4 hours. As an early adopter of technology and a music-first audio buff, I can live with this because none of this changes the fact that the sound quality produced by my Q Accoustics standmounts via and NAD amp and a Chord DAC is really excellent.
