In my opinion the sound quality of the BS2000 doesn't warrant to jump through hoops. I would look at connecting an Ipod or Airport Express or something like this.
If you have an Iphone or Ipod touch I would like to recommend Apple TV. I also like the Sonos system conceptional even though the design is clunky.
You can convert the FLAC files into something high quality if the MP3s included are not good enough , are you on PC or Mac?
