I've owned both the R200 and Denton 80th Anniversary (not 85th) so not quite the comparison you were looking for.
I think the R200 may be too large for a desktop/nearfield setup. I would look for a 5" driver for that application so the R100 might be more appropriate in that usage case.
The ring radiator tweeter can kind of beam if you sit on-axis so you will likely need to turn them slightly off-axis to avoid brightness.
Another option to consider for a desktop is Wharfedale Diamond 12.1 if you are trying to avoid brightness/clinical sound:
This is a review and detailed measurements of the Wharfedale Diamond 12.1 bookshelf speaker. It was kindly purchased by a member and drop shipped to me. It costs US $399 for a pair. The look and feel of the 12.1 is definitely above the budget category: The back is rather pedestrian but...

However I don't feel those have a concert/fun like sound (I had the 12.2), more of a neutral sound signature.
If you are looking for concert/fun type sound, maybe consider the JBL L52:

Lots of subjective reviews on YouTube saying those have a fun sound signature without sounding too bright and JBL generally makes good loudspeakers.
