When I was a little older than a wee pup and totally into this hobby in my mid 20's, I would venture into a few Phila area stores and pretty much wanted everything
Sassafras Audio: Perreaux, cj walker, Maggies, cj, Audio Research, Tandberg, Sonographe
Chestnut Hill Audio: Rauna Tyr's, Moscode, Counterpoint
Danby Radio: Sequerra Met 7's, early Thiels, Nak Dragon TT, McIntosh
Stereo Trading Post: basically a musuem of the coolest high end used gear, you name it, it was probably there in the mid-late 80's
There were a couple of other joints Community Audio & Sound Service (aka David Lewis Audio) but I didn't go there that often.
