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.

Which did you prefer, AN, Harbeth , or ProAc? OP- It's a bit off your path, but Don Better Audio has a heck of a lineup. I believe you could hear DeVore, Vandersteen, Ryan.... and more.
Deja Vu is quite a different kind of store--a lot of old gear, but mostly "new" gear that they make in-house or through exclusive associations with builders in Europe that build new stuff from old parts.  Some of the speaker systems based on Western Electric, IPC, RCA, Jensen, etc. drivers are fantastic sounding.  Even better than their in-house speakers are their tube amps, linestages and DACs made from a mix of vintage parts.  You can hear AN, Harbeth and ProAc at Deja Vu.  You can also audition DeVore at Command Audio in Falls Church Va.
