Actually, Madrigal bought Levinson (late '80s) and later Harmon bought Madrigal (in the late '90s, I think)
Robert, the CZs are extremely articulate (some might say bright -- I wouldn't). They compare with cables like Straightwire Virtuoso (a little better), Magnan Silver Bronze (about the same) and Purist Venustas (not quite as good). Very sytem dependent. I think they'd be excellent if you needed a long run for some reason. I only tried them in 1 to 2.5 meter. Also, they didn't make a lot of product in single ended, so you'll mainly see XLR. Also, I've never figured out what the difference is, but there is a CZ Gel II.
