I used to think that 32 bit engines were "better" than 24 bit engines, and *theoretically* that is true. But here's is a simple fact to disuade that idea:
Analog Device Sharcs have been out for more than 4 years and are 32 bit. Most Sony receivers use these now, among other manufacturers.
But Motorola is still at 24 bit. That includes the new Anthem and B&K Ref 50 processors:
