My vote for Northampton Audio / Spearit Sound in Northampton Massachusetts. Been a constant customer of theirs since 1977 even though I have not lived there since 1983. Have never been treated better. They have a web site.
The Best Audio Dealer
My vote for the best dealer award goes to Mario,owner of TOYS FROM THE ATTIC info@tfta.com This guy helped me break into analog.I made alot of mistakes because "Dave,you don't listen" Any way Mario was always to the rescue.He,over the phone has helped me build an awesome sounding stereo.He has always given me the Best price and I know he hasnt made much money from me.He calls me on occasion to see "whats up" I have never met the man or been to his shop because its over 300 miles away
