I agree with the above. I do have the SL3 in the family and recall that that crossover design benefited from biwiring. I think the old Stereophile review of the SL3 recommended biwiring. I have mine externally biwired with twin runs of DH-Labs Q-10 Signature.
That being said, other ML's may not need that even if they do accept biwiring. I believe alot depends on the xover and also how an amp senses and reacts at a given time to the woofer vs. the stator impedance through 2 different cable runs combined at the amp end. May want to borrow an extra pair of cables or a new biwire set and judge.
