Sooloos store is just a NAS box. No need to even copy files off to use with a different system. Many people use their Sooloos files as the media library for other music systems. I have Sonos mapped onto my MC200 and they share the same files. The only issue are files ripped within Sooloos where you dont see the metadata - those ripped by other means like dBpoweramp, metadata works fine.
