which excels at Rock and Roll

I definitely recommend Totem speakers for a small room They are punchy, musical sound speakers as opposed to hyper detailed speakers. Great speakers. I have a friend that had bought thin towers, sounded great. 

With an SVS sub, I would think your system really kicks with Rock music. The king of kicking with rock and roll in my opinion is JBL. That's what JBL does best. L100 or the studio monitors for higher end. They pound through you, solid, and can get loud. A perfect party speaker. 

Have I missed something or hasn't anyone mentioned Klipsch. Small room and the new Heresy iV's might work well with your gear. 

Happy hunting.

I agree on the McIntosh amps for R&R

Try JBL L112 , L300 , ESS monitors ,Acoustic Research AR9 these speakers all ROCK
