Another consideration not brought up yet is to have someone re-cap your existing aging 5500s? New caps and a fresh tweeter will work wonders on an old 'tired' DSP speaker.

I would also add that I have listened to the 7200s, and they are indeed a nice step up from the 5500s. If you are looking to expand to 7.1.4, you can still consider a re-cap on those 5500s after you buy 7200s.
