Blu ray and SACD

"I am in the process of purchasing a Blu ray player and I would like to know whether any Blu ray player will play SACD in its true format as it was meant to be played (not just because it is compatible)."

from what I know the two new SACD/BD players from Marantz UD9004 and UD8004 play SACD natively.

PS Does anybody know any Blu-ray player that will play Blu-ray discs without converting 24bit/48kHz do delta-sigma?

BTW, you'll find a complete list of SACD/BD players here:
