The SoundStage Pro uses separate D/As and A/Ds rather than a combined CODEC,
as the separate parts offer better performance.  For the D/As we use two
Crystal4329s (see http://www.crystal.com/pub/da.htm) that have a S/N of 
112dB.     For the A/D I think it is 5390 with S/N at about 107dB or better.

Note: The non Pro vesion of the SoundStage that came out a year ago used
a CODEC like the Defina and Sunrize.  It was the Crystal 4225 (the quad 
channel version of the 4215).  We wanted better quality than that.
