I don't really know what you guys are talking about, my system handles rock just fine using ML Aerius i. Just not loud thats all.
Rock and Roll Snobbery
Can anyone explain why otherwise high end, musical systems might "not be good for rock and roll?" Or why a system that sounds fine for pop and rock might not do justice to classical and jazz? It seems to me that a great system should sound good with all types of music and that a good for classical system might be deficient in bass which is not exactly state of the art.
