I haven't heard one, and that includes some good ones -- including Forsell Air w/Levinson DAC and Electrocompaniet.
I have also found, when I turn CD's up loud, they hurt my ears. In addition, you don't get the broad sound stage and life to the music that LP's give you.
That said, the Sonic Frontiers SFCD-1 is a very good sounding player. You also might want to consider a DAC with your Marantz, as Ken suggests. He's also right about isolation. I've found Symposium Rollerblocks under my CD player to offer significant gain in smoothness at the top end.
BUT -- don't expect to get anything that sounds like a record.
