CDP or DAC for $4000 budget


Hi friends,
I intend to upgrade all of my system, speakers will be Marten Bird.
My taste is neutral, soft, treble should not be so high, bass soft or enough.
Could you please suggest some CDP or DAC (used) for $4000 budget? By the way, please suggest an amp to run Marten Bird.
As I study from the Internet, there are some candidates:
1. MBL 1511 version D + 1521
2. Emm labs CDSA SE
3. Metronome CD 1 (Tube CDP)
4. Einstein The Last Record Player
5. Audio Aero Prestige Signature
6. Audio Aero capitole ref se
Thank you so much!

Dear Guys,
Be honestly I haven't try any of them before. As you can see, I am building up a new system matching with Speaker Marten Bird and my taste is natural sound, not colorful.
@ Akg_ca: Rega Isis seams to be around $7000 which is voer my budget.
@ Mitch4t: Do you think Audio Research Reference CD7 is a right choice?
Some people recommend me for Weiss DAC202 and Berkerley alpha series 2.
What do you think?
