It is a fairly newer unit. That is for sure. The break in period is definitely not even close to complete. I was very suprised. The CAL is more liquid in my opinion. Maybe I will listen to the unit after it has been broken in. It is very new in all fairness. but the Cal player is stunning to say the least. I am going to buy the interconnects they gave me to use. They sound wonderful. JPS Labs Alluminata. I guess the difference is this: when I have Celine Dion on with the Cal, i get goose bumps, that is not the case with the Marantz. But maybe I have to give it a chance to break in. I still think that it will never sound as rich and liquid, and involving as the CAL. This already the 5th player I have tried. Maybe my Cal is trying to tell me something.
