To answer my own post after two weeks with the DCC2/CDSD combo: Break in with SACD is as crucial as with CD. The sound I'm getting now with SACD is aaaaamazing. It reminds me of the EXPLODE command on a computer program I use i.e. PCM exploded; bass, timbre, air etc.....left, right, front, back ...every where. I'm at the point where I can say I am finally satisfied with the sound of my system, limited only by the quality of the recording.
