Yeah, but those were just the power cables, Peter. These look like they're connected to the speakers themselves. Here's a picture of the Acoustic Zen Gargantua power cord. It's over an inch think and just a mere $1500 for a 6 footer.



edit: after a little searching, it looks like Acoustic Zen makes a speaker cable that's basically the same idea as the Gargantua, so it's very possible those speaker cables are the Acoustic Zen Holograms, which will only set you back $950 for an 8ft run.
