Where to listen

I currently live in Hawaii and there is just a single dealer (that I know of). He is good but with a very limited selection. We are thinking about getting new speakers but need to find a way to cover a sizeable amount of dealers in a single mainland trip. The speakers I am interested in are Wilson Audio Sashas, Magico V3, Focal Scala and the Kharma CRM3.2FE

Can anyone recommend an area, say with a 200 mile radius, that they could recommend dealers for the above products.

Thanks
James
