Bifwynne, most people confuse Community Audio with the defunct Jack Rubsinson's (still active in the industry - I think now with VPI?) Chestnut Hill Audio, which used to sit right below the Ben Franklin Bridge. Community Audio is located on Germantown Avenue in the Chestnut Hill section of Philadelphia. John Adams (owner) and Bill are normally there, and extremely welcoming. If you do make the trip, further up the hill is Hideaway Records, which I suggest you also visit.
Even when everyone else abandoned it, they stuck with both tubes and vinyl. Most of the brands they carry have been with them for a very, very long time - Cambridge, Gallo, JMLabs, Jolida, Linn, Music Hall, Naim, Rega, Rogue, and Totem. In the past, they've also had Cain & Cain, Electrocompaniet, Fried, JSE/Infinite Slope, NAD, Osborn, and Redgum.
