My Classe amp drove them with ease. If I could find similar performance with smoothness my search would be over.
The Paradigm's tilt upwards in the treble - if you turn the treble down then they may work better for you. If they sound harsh then you may have trouble driving them (they are like a 2 ohm load in the bass and may cause amp clipping/IMD distortion making the mids and treble harsh). Great speakers but not a smooth load.
