Speakers for Rock

I'm looking to buy the system of my dreams. I listen to mainly rock music - everything from 50s, classic rock like Led Zepplin to new stuff like Blink 182. I listen to country, jazz, classical here & there.

My question is - what brands of speakers are best for rock music?

I've been looking at B&W CDM9's pretty seriously, as well as Thiel or maybe the 804s used. But I often hear comments regarding the B&Ws that they aren't the best for rock. I'm not sure where to start on this search - there are so many brands and most shops only sell a few so I'm looking for some pointers......

(As for components, I've been thinking of Rotel separates or a B&K 805.)

Thanks for the help!
