A friend and I are going to take a road trip to a major metro area within a few hours' drive of Baltimore to look at HT equipment (front projectors, amps, processors, etc.) and in preparation for it, I would like to know the best places to go in either the Philadelphia or Washington, DC area. Unfortunately, there isn't much in Baltimore so the road trip is necessary. We want to go somewhere where we can hit a couple of really good B&M's in one day. What are the best places to go in these two areas or in other areas of similar proximity (i.e. East Coast within a few hours of Balt.)? I'm looking to review things like Sharp and Seleco DLP front projectors, Lexicon/Classe/Bryston/Integra Research processors, Monitor Audio/B&W/Vandersteen speakers, Cinepro/Bryston/ amps, etc. Thanks!
