I have a Marantz CD5001, which is the previous model, but I believe that the only differences between the CD5001 and CD5003 are cosmetic. The inboard DAC, IMO, is not very good. I purchased the CD5001 to use as a transport, and I haven't had any problems with the unit. I tried the CD5001's analog output, and I would not recommend the CD5001 as a stand-alone CDP. If it were me, and I understand that it isn't, I would find a DAC that integrated with the rest of my system and then try an inexpensive CDP or DVP as a transport (but not a extremely cheap DVP with a noisy switching power supply).
