I now live in Maryland now, but I have a 25 year relationship with Northampton Audio/Spearit Sound in western Mass. Richard Moulding, Jack Tozzi and the staff are all great. They will take all the time you need and will never pressure or talk you into anything. I know they will let people take stuff home (a friend has a Conrad Johnson Premier 17 preamp of theirs for the Easter weekend). I am not sure what the policy is.
I brought some Nordost Quattro Fil cables of mine to a guys house in Virginia for a demo a couple months ago. Was fun to make a new audio friend and see someone elses setup.
A couple years ago when I sold my B&W Matrix 804s, the guy who bought them demo'd them in my house before he decided to buy them.
