My house has 4 sets of JBL in-wall speakers, each with a volume control, wired to a central point. My music is stored as FLAC files on a ReadyNAS NV+.I'm looking for a central system player that can be controlled remotely, but has a clear display. My thought so far is to buy a diskless Olive One (which plays FLAC, has an attractive display, and can be controlled via Android app), connected to an amp or receiver (need to check specs of Olive One integrated amp), and a speaker selector. That would allow me to play from a central point, control from that point, and control via app. I had originally planned to use a Squeezebox Touch, but... Any other suggestions ( <$800 total)?
