Summary: I am less than 3 weeks into my time with the Marantz NA-11S1; it is displacing my OPPO BDP-95 as the primary source in my system (ModWright LS100 & KWA100SE, KEF Reference 205/2, midrange Nordost and WyWires cabling). I mostly listen to 24/96 or better FLAC files streamed from a NAS, although I have acquired a dozen or so DSD files for use with the Marantz.
Pros: The Music! It's beautiful! Superb build quility. DSD capability and fidelity. Gapless FLAC playback (at last!!!)
