I live in Boston. Try going to the McIntosh website and typing in the Boston area code - 02201. There is one real audio store (Natural Sound), a group of custom installers who specialize in home theater and "connect homes", and a bunch of Magnolias.

I had a different experience in DC in the early '80s. I wanted to buy a turntable that Meyer Emco carried. I was in my late '20s and dressed like many academics of that time. i went to the store with my wife and we spent a hour trying to get somebody to talk to us. It was busy, but nobody had the courtesy to even acknowledge me. When I asked if somebody could help me, they just brushed me off. So, I took the money I had in my pocket and left. I ordered the turntable from a company in Florida.
I hope your last paragraph was not aimed at me. I was just reporting the current corporate arrangements and my experience at one of the new Magnolias. My only "opinion" was that, at least in the store I was in, they were not really equipped to sell high end gear to knowledgeable buyers. I made absolutely no statement about the sound of McIntosh equipment.
