Yeah, I bought two pairs of used 2.0m AU24 as well. One from a friend, and one from a guy on Audiogon. (I lucked out that I managed to find two the exact same length, although 2m seems to be a pretty popular length. Together the price was about $900) Keep your eyes open and you might luck out as I did.
FYI, I let slip through my fingers a bi-wired pair of AU24 speaker wire, which went for $800, shipped no less. (Dumb, huh?!) Apparently, the way AU24 is bi-wired, (or at least this pair was made), was not internally bi-wired, but really two pairs of Au24, but with only one set of terminations at the amp end. This seemed like a logical way to do it, given the thin nature of the cable itself. Therefore, I doubt there is much difference between the way I did it and the way these were made, IMHO.
FWIW, while I did not A/B the cables in the same sitting, my buddy went from the AU24 to the Nordost Valhalla cables. I got to hear both in his system, and while the Valhalla was slightly better, it was only very slightly better. (Not in my mind worth spending $3K vs. the $500 for the Au24.) I think the imaging was a little better.
I think the AU24 is really a pretty impressive speaker cable for the money. (I use it for my I.C. between my cdp and my preamp, and it is very good there as well, but there seem to be quite a bit of competition in the I.C. market at that price range.)
