My friend could not drive them properly with antique soundlab monsoon monoblocks. Thick, slow, bloomy sound, for some musical, for some boring. He thought boring. Now he drives them with Spectron musician monoblocks. Now he is on the other side of the pendulum: fast energetic but cold and tipped up sound. We recently tried with nuforce monoblocks (plus PS powerplant and top of the line Harmonic technology cabling). That configuration seemed to be a balanced way between the two extremes.
