I've set up a server with Squeezebox Duet and iTunes, and ripped a large percentage of my CD library into the PC that I'm using as an exclusive music server in Apple Lossless code. Have to admit that the sonics I'm getting is quite impressive. I'm wondering if anyone has set up Squeezebox and the Squeezecenter to use other music management software and tried to integrate it? Maybe something like Real, Amarok, Windows Media Player, or Foobar? Something like Foobar may be an advantage due to the numbers of file types it can support like FLAC files from someone like Music Giants. I'm not sure if a FLAC file will work with iTunes, but I may just be ignorant of the facts. Anyone done experimentation or have good experience with the Squeezebox and anything other than iTunes?
