I did this, all ripped to FLAC and onto USB. Sound is fantastic. (Tidal was great while I had trial hifi subscription) Have also loaded on my NAS and bought a Cambridge Audio CXN v2 network streamer for hifi system. FabI ripped again my entire CD collection with loseless quality, on an USB stick, when I got the iPace. Really enjoy the quality of the 825w meridian system.
