CD player recommendation with good built in dac under 1k new or used? please and thanks

I have a Musical Fidelity M2SCD, which retails for US$ 1,099. I actually just use it for a transport and run it through a Denafrips Ares II DAC (along with my streamer). However, it still sounds very good with its internal DAC.

In the under $1,000 category, I would also check out the Marantz CD-6007 or the CD 60.

Do you want access to the internal DAC for other digital sources?

Can you get a transport and use your current DAC? If so, Audiolab 6000CDT and Cambridge CXC v2 are very good budget transports. 
 

In budget CD players I would look into Rotel, Marantz, may be a used Rega.
