Plinius 9200 or Gryphon Callisto 2200

Has anyone been lucky enough to do a compare/contrast AKA A/B of the 9200 and 2200?
If not, has anyone out there owned the Gryphon Callisto 2200 and could give me some indication of it's sound? Any Pros Vs Cons?

Any info is always helpful.
Thanks in advance,

J.
