Tekunda, Jonathan is pulling your leg on the cable issue but is sincerely recommending the Wolcotts.
if your preamp has 2 outputs and you still want to try bi-amping you actually only need to attenuate one side of the bi-amping (you would need to experiment to discover which side). you could use the Placette RVC (remote volume control) on the stronger side to attenuate it to the correct level. there is a possibility that this might not work but it is a much simpler solution and more transparent than other crossover solutions would be (and with those great HMS cables why lose any transparency).
you would need to try to keep the total interconnect and speaker cable lengths the same to avoid small timeing errors but you are a "cable guy"....right.
