Another unorthodox (in 'audiophile' circles) suggestion: B&O Beolab Penta, an early pair (Penta I) can probably be had for your budget. I've owned a couple of different pairs and lived with them in apartments . . . and for rock, metal, and punk, they will do exactly what you're after.
The bass response is full and warm but not boomy, but slightly gritty in a way that fits this music well -- the bass has some adjustability as well. The Penta I's lack a bit of sparkle for classical and jazz, but really bring a sizzly rock/punk recording into nice focus. They crank up really well . . . but also hold together at low volumes.
Oh and they look cool, hold their value well, are relatively insensitve to room placement, and have pretty decent monoblock power-amps built in. RCA out from your preamp (or variable out from CD, DAC, or phonostage) is all that's required.
