Excellent selection of new and used but 45 mins outside of Boston
I shop in Cambridge - Boston area three or four times a year. I visited Stereo Jacks on Mass Ave this past August and their stock of used lps was quite low. Nowadays I usually visit Looney Tunes (very close to Berklee School of Music on the Green Line) and that's about it. Looney Tunes is a fairly large store and because of their location, they carry a wide array of new and (mostly) used lps.
You can always check out Newbury Comics on Newbury Street and in Faneuill Hall but their selection is pretty limited.
