mcintosh c200 vs. c46

Hi. Has anyone done an a/b comparison of these two? If so features aside, sonicaly how do they differ? Using 501's with Maggie 3.6's.

I a/b the C220 vs C45. thought the C45 was a little too polite. Throw some tubes in your system.............Bought the C220..might upgrade to C500 or the MEN220
The 200 is the best, or at least for has a fantastic phono section, the balanced circuitry and 2 chassis.
