I owned 8200 mkII and have briefly heard the 9200 (30 minutes?). I'd say the 9200 has definitely the same sonic character overall, and strikes me as a little more honest and clear than my memory of the 8200 mk II. The bass seems tighter, cleaner, and very satisfying. The high end seems a little clearer to me. I do think it's a step up, and noticable, but can't comment on the relative value.
