"Aball"
Hey "Aball"..... how are you doing, and welcome to the Nation's Capitol. Now, as far as audio stores are concerned here in the Washington, D. C. area are concerned, here are a few that you should check out as soon as you arrive in town.
And they are:
(01). Deja Vu -- Mclean, VA (I've never visited them, so I don't have an opinion one way or another since I am mostly solid-state and digital, but if you like tubes and analog, then by all means, pay them a visit).
(02). JS Audio -- Bethesda, MD (my overall hands down favorite. They are more so solid-state and digital than they are tubes and analog. But they give unbiased honest opinions all the time, and the staff is very accommodating. They are in the Meridian, Bryston and Mark Levinson camp).
(03). Myer-Emco -- Washington, DC area (the place you want to go to if you are interested in McIntosh or Meridian).
But I would stay away from SoundWorks if I were you. They are the most stuck up people I have ever seen or dealt with.
Anyway, welcome to DC, and I hope your visit is an enjoyable one.
