Information on Denon dcd-3520 cd shuttle/player ??

I am currently running a pair of Infinity Kappa 9's with a Mark Levinson No. 23 amp (more power to come soon), a Denon DAP-5500 pre amp and am in need of a good cd player. I have heard some very good things about the Denon dcd-3520, does anyone out there have any input on this unit? I know that it is built like a tank, versitile and runs 20 bit technology. I am having trouble finding specs on this unit. Does it read & play cd-r / cd-rw ? I can't seem to remember when that technology came out. Any feedback on this unit would be appreciated.
