Road trip to demo $10,000 speakers

I'm going to take a several hour road trip to the Washington DC/Baltimore area to demo some speakers in the $10,000 range for a once in a lifetime purchase. I plan on listening to some Magico A3's, Aerial Acoustic 7T's, and Spendor D-9's. One of the dealers also has Paradigm Persona 3F's on the floor, so I'll take a listen to them too. While I'm up there are there any other speakers in that price range you'd recommend I try to locate and take a listen to. I'm open to and welcome your suggestions and will take the time to research each one as well.

I'm not in the market for used equipment. Thanks for any and all suggestions.

Mike
