I have used ARC D115 mkII and ARC VT100 mkII amps wtih the 3.5's with excellent results. In fact you can "quasi-biamp" with these amps (ie. use for example 0/4 taps for the mid/treble and 0/8 for the bass.) These amps are nominally 100W. Thus, it is not accurate to claim that the 3.6's need excessive amount of power to perform up to their capabilities.
