Choose MX200 when the room fits 7.2.4.
It is the cleaner modern solution: smaller rack footprint, uniform high-bandwidth HDMI and Dirac Full Bandwidth.
PROCESSOR COMPARISON
McIntosh MX200 vs MX123
McIntosh currently offers two very different processor philosophies: a compact modern 11.2-channel Dirac platform and a larger 13.2-channel Audyssey platform with extensive connectivity.

DECISION POINTS
Choose MX123 when the extra channels and connectivity are genuinely useful.
Its 13.2 architecture, three HDMI outputs, multizone capabilities and broader format support serve more complex systems.
The correction platform is a major difference.
Dirac Live and Audyssey MultEQ XT32 imply different measurement, target and commissioning workflows.
Check the video topology carefully.
MX123 has far more HDMI sockets, but only a subset support 8K60/4K120; MX200 has fewer sockets with a more uniform modern bandwidth story.
