Options on a new DAC for my Sony 333ES SACD player

I do not believe you will realize any benefit from an external DAC.

In the opinions of people like Rick Schultz of EVS, a modded Sony SACD player such as your SCD - 333ES(which I also own), is a good bit superior to a player with an external DAC. He feels so strongly about this that he stopped making his own highly regarded DAC to focus on modding SACD players. I believe that what Rick says is the case, especially, regarding the three DACs you listed.

Personally, I find that the player is very nice as is. All components err in some ways. The SCD - 333ES errs in the correct ways. Falling short in resolution, refinement, air, and delicacy in Redbook mode. I would not be able to live with the player if it was bright, harsh, analytical, sterile, not musical, or "digital".

Its problems should all be addressed by the mods offered by people such as Rick Schultz, Dan Wright, Richard Kern, Stan Warren, etc. I say that because parts/circuit upgrades always improve the type of shortcomings that I listed for this player. As your player is already "Modwrighted", I fear you can go no further. For now.

I am using this player as well (unmodded) and am serioulsy considering a high quality one box cd player (like a used levinson 39 or Cary 306/200) with a digital input so I can have the benefit of a top quality single disc transport and better DAC.

I imagine you would do well with any of the DAC's you mentioned. Obviously, listening to different DAC's, when possible in your own system, is your best bet.
