I am breaking in a pair of the Super HL5's. My early sense is that they are quite versatile and are fine for rock. If I listened primarily to rock, I might not choose them, but then I would not have chosen the Quads, Avalons, Spendors, ProAcs, Theils and Ref 3As that have spent time in my systems over the past decades. Well, maybe the Thiels and ProAcs.
