Do room treatments. I'm using Primacoustic panels from Sweetwater Sound in a moderately small room with Vandy 2Cs and the difference between untreated and treated was jaw-dropping. Bigger improvement than ANY gear change will do. Remember, the room gives half of what you will hear, (maybe more). And yes, I LOVE my Vandys. Also, agree 100% with tomic601 to get Jim Smith's book Get Better Sound. Indispensable tool to get the best setup to play the room. Finally, I also think you should get the 3As, but that's just because I like Vandys.
