Joseph Audio dealer in the northeast?

I'm very sorry to start a new thread but I've done everything else I can think of, including posting in other existing threads here and writing to the company. They're not exactly like unicorns but maybe snow leopards: many reports but few actual sightings. I can find one rather obscure dealer on Long Island, Doug's Tubes, though it barely looks like a stereo store.

So: does anyone know any dealers in the Northeast? 

Many thanks!
