What's your budget? I am using Virtual Dynamics Audition speaker cables with my ML Aerius's, and the sound is fantastic. I've actually demo'd them against Analysis Plus and DH Labs Q-10's. No contest, the Audition's are in a different league.
The Aerius are already very detailed speakers, and the Audition cables only strengthen this positive attribute. Also, the one area where I was having problems with my ML's was in the bass register--bass was too "loose" and muffled. While part of this might be attributable to the design of the speakers, I found that using solid core copper cables improved the bass performance (for example, my old Audioquest solid core cables did a good job, and are cheaper than the Auditions), and (again) the Virtual Dynamics cables were the clear winner.
So... My recommendation would be to call Rick at Virtual Dynamics (www.virtualdynamics.ca) and get yourself a biwired set of his cables. Otherwise, I would recommend that you look at some solid core copper cables, like a set of Audioquest Indigo's or Tara Labs cables.
Best of luck.
