The marantz as a transport is limited by quite high levels of jitter on the digital out. I own a CD67SE and when I paired it with a Monarchy 22B DAC I heard virtually no improvement. Then I added a Monarchy DIP and the sound snapped into focus.
I like the marantz in that it's inexpensive, well built, and very reliable, but I think if you add a DAC it will have to reclock the signal. A non-reclocking DAC will probably not gain you very much.
So, having said that the DAC that is currently all the rage is the Benchmark one. I have not heard it but by all accounts (and I don't think I've read a single negative review) it is very good and has excellent reclocking.
For $1000 you would probably do worse than the benchmark.
