Best matching DAC for TEAC 25X CD Player.....

Hi, Any one using separate DAC for this player..
Please share your opinions becoz am planning to purchase
a external DAC.
Upgrade the internal 25x DAC. its uses AD1862N-J DACs ships which are one of the BEST EVER MADE.
I have done upgrades to my VRDS-25 and it beats Chord DAC-64 which I had in my possession.
