I would say try any of the Klipsch classic line like the Forte's,Chorus', and Quartet's. They can be found on the used market from $300.00 to $600.00 depending on which model and condition. Very dynamic for Rock music with a really nice midrange. The Onkyo A-9555 is a sweet sounding affordable int. amp that has a "tube-like" warmness that melds nicely with horns. I know an overused phrase.
