Yes, Aerial made a few changes in the 10T over the years without changing the model number, the last of which was an improved tweeter, which Aerial can still supply (at least a year ago they could).

If you keep speakers for 15 years it is worth the trip. You might also check with the NYC audiophile clubs, a 7T owner may be quite happy to show off their system. Another option is to contact Aerial, tell them the serial numbers and find out if you have the last version of the 10T; if not you can purchase a new pair of the upgrade tweeters from them.
Love my 7b's as well, and they look great in my room without overpowering a room visually, plus the rosewood looks great. Never heard a set of 10t's, but I can only imagine how nice they sound. If it's a look thing, you could probably get a set of 7b's for what your 10t's would bring. There was a set of 7b's here recently for sale. Maybe try them first if you don't want to part with your money.
