I really like Gifted Listener Audio - bought a lot of my stuff from there.
I've also been to Evolution A/V in Tysons Corner.
There's also Command Performance A/V in Falls Church. I've met some of the guys from there at the Capital AudioFest and they seemed to be good dudes.
If you're into headphones, local Head-Fi'ers usually meet at the George Mason Regional Public Library. There's one coming up Saturday, November 7 from noon - 4:30 p.m. Here's a link:
