Whatever it was I said about little Linux streamers...
...I take it all back!
Right now I've just set up a Raspberry Pi with the HifiBerry DAC board. Running volumio software, which you control from a web browser. It's still busy indexing the NAS but playing fine. Sounds good too. Can also function as an Airplay destination, so easy to stream Qobuz to.
Pretty slick little package, actually. For a bit over a hundred bucks!!
