Yikes! That's tough! I have a pair of LCD-2s on order. I want to research headphone cables while I wait and BEFORE I hand over the equivalent of the cost of the cans for a dud cable combination.
Sorry about that. Please continue on. The problem was with someone trying to hijack the thread into one more appropriate for the Sound Science forum.
Back on topic with what you've been writing about, I've gone back to copper with the LCD-2s. At first, I liked the results changing the cable to an APSv3, but am now preferring the 8-wire Norse that seems to me more along the lines of my preferred "just-get-out-of-the-way-of-the-music" kind of sound. Some of that is either the headphones and/or my brain burning in with them -- possibly a combination of both.
