I realize I'm jumping in late here. Without getting into the technical aspects of why and just listening to my ear, I've found the Kimber "TC" line and mid-grade Cardas seem to sound best with the Maggies. A longtime friend is a Maggie advocate and did 30-day demos of dozens of speaker cables from a local hi-fi shop, usually 3-4 at a time where he'd keep the best one from each week and exchange the others to compare. He liked the Cardas a slight bit better in some areas but we both agreed the Kimber 8TC was the best *with his setup*.
