As mentioned by some reviewers here is the functionality of the display screen is too low, the numeric representation - especially compared to the old Denon CD players - too small.
However, the positive side, I would note that the DCD 510 also from my old Denon universal remote control stereo receiver of 1996 (DRA 385-RD, who had never had a repair necessary) can be controlled.
Well, there would not be reading problems with some blanks, I would classify the unit as well and better, so unfortunately only 3 points (one point more, because I have solved the blank problem in my own way).
