CD Recorder Connection

I'v'e Just bought a Marantz DR6000, and I was wondering which port is the most suitable for connecting it to my Nait 5 Amp.At present my turntable is connected to 'Aux 2'and I have a Cassette Recorder using the 'Tape' port. All the other ports are free to be used. If need be, I could disconnect my Cassette Recorder in order to use the 'Tape' port. Any advise would be appreciated.
