I love a good excuse to buy more RPis and have thought about doing something like this. However, I already have a cheap bluetooth dongle that I plugged my stereo to via P2. Is there some advantage to this setup (beyond range)? What I'm really considering is a web interface, with search, playlist etc and a huge SDcard with all my music connected to a RPi. Currently all my music is on my Mac and Apple Music Home Share is a bit flaky/slow at times.
