Volumio is very easy to set up, although a little work was involved in getting it accessing music from my Synology NAS. The player interface works from every browser I've tried and is very responsive. The mobile app is very similar to the web page and not really necessary, but I purchased it anyway to support development. Some areas of Volumio need polish: 1. it really needs better sorting options (albums, etc), 2. I'd like to have the option to hide 'My Volumio' from the main menu, 3. embedded album artwork is not supported, so you need to add cover.jpg files to every album folder. Overall I am very happy with Volumio and would recommend it to those who want a simple-to-use digital source/streamer.
