speakers with balls

Magnepan 1.7 or the 1.7i’s will do the trick with proper amplification and speaker placement will knock your socks off. I would recommend that if you purchase either make sure you get a pair of DWM’s. They worked great when I had the 1.7i’s.

Second the Dynaudio recommendation if you’re looking for an “audiophile” speaker that can still rock. The Esotar drivers can handle a lot of power without too much compression. For a smaller speaker, the Special Forty is very ballsy, and has a full mid bass that I think will work well with rock. A little under damped for my tastes tho so may not be your cup of tea if you like super tight bass.

And no offense to the Maggie folks, but I don’t see how those otherwise fine speakers could ever qualify as “rockers”. :)

Another vote for Goldenear. The built in powered woofers on some models are very well integrated sonically and offload your amp to spend its energy on the mids and the high-tech tweeter.

Uh.... Not even close. Those things don't use line level inputs. Those are low gain, digitally manipulated, speaker level amps, and the measurements make that very clear. Those speakers present a fairly benign load to the amp in the bass region, but they in no way excuse the amp from driving a load just as it would a driver directly.
