Good HiFi stores in NY, Washington DC area


Hi, I'm looking for recommendations for good HiFi stores in NY, NJ, Philadelphia, Delaware, Maryland and DC metro area. I'm looking to buy good condition pair of used/demo Speakers (for Pass XA 30.5). I've shortlisted wide range of brands (coincident, silverline, Von Schweikert, clearwave, DeVore, Tannoy, Proac) etc. or any other suggestions please... My priority is to listen to...

Coincident (Super Eclipse, Super Victory)
Silverline (LaFolia, Sonata III)
VS (DB 99)
DeVore (9s, O/93)

I can travel out of my way for the above models. I plan to audition and buy speaker during my short USA trip in July 2016. Thanks

In NYC I would recommend making an appointment to see Gideon at Audio Arts. In my opinion, it will help to open your eyes to what is possible. If you haven't heard Zellaton speakers before, I suggest that you do before purchasing others. 

Good luck and enjoy your trip!
Don't forget Wes Bender Audio and Jeff at High Water Sound - no trip to NY would be worthwhile without seeing these guys.  If your in my neck of the woods (Eastern Long Island), check out My Favorite, Roy at Audioden.  
Was at Deja Vous Audio yesterday.  I couldn't believe the sound I heard.  I have CJ gear.  They hooked up a CJ 60 Watt amp running some 95 DB Audio Note speakers, some Harbeth 5' and Proac speakers.  A great store and worth the trip just to see the vintage gear.
