D400. Love it. Very quiet, music comes out of a black background. Tremendous air and separation. Tight, firm bass, great vocals. Lots of 3D. Built-in preamp, dac (with DSD now), phono and amp. All-in-one operation with the ability use the front end to another amp. If you can enjoy a simplified system, it is amazing. If you are a tweaker, you might get fidgety.
