Where can I audition amps near Boston?


Hey all -

I'm planning to upgrade the power amp in my system in the next few months.  Brands I'm interested in are Bel Canto, McIntosh, and Quicksilver.

Does anyone know anyplace near Boston that carries any or all of these brands?  "Near Boston" for my purposes could include Rhode Island, eastern Connecticut, and southern New Hampshire.

I would love to be able to hear before I buy.

Thank you so much!

@oddiofyl pretty much covered the whole audio gambit in the MA area. I live in between Boston and Worcester, and have been going to Natural Sound in Framingham for many years. They usually have a great used section too. It’s not that big of a store, but they’ve got 2 nice separate listening rooms. Good selection of turntables too. 
Westford audio in westford mass...Jim Uban...Carrie's many esoteric brands. 
I second audio video Therapy in Nashua.  Only place I do business with.  Very friendly and awesome people to deal with.  Large selection and they also have a used section in the basement.  I've seen parasound,  threshold,  krell and many others there. Huge store, lots of options.  Basement is like candy store. Worth checking out.
I second Goodwins for a good experience I had.  I stopped in for a look around while on business a few years back.  They offered to ship me a demo phono amp to try out.  Not much of that around!
