Do you have access to a McIntosh dealer? Like you I am considering a tube preamp upgrade (from my Mac C220) and intend to demo the C2500 at some point. That's their top-of-the-line pre insofar as single box units go.
The inclusion of a killer DAC in that preamp may not be something you would use (hence needlessly driving the price up) but it is a large part of the appeal for me as my digital front end (Marantz SA7S1) is 2007 technology.
