Well, I got the Audio Note AN-Vx 20 strand silver litz cable terminated for the LCD-2s, without any problems. I've been listening for extended periods of time to both cables. There's no doubt in my mind that the AN cable is "better" in every respect than the stock cable. It clearly adds more detail and tightness to the bass and opens up the treble. The mid-range is smoother, but more detailed. All in all, these cables are more relaxing to listen to than the stock cables and yet at the same time can really wrap their hands around the music. These cables are just more enjoyable and more like music.
That said, they would be terribly expensive these days. I haven't the latest price sheets in the US, but i think a 3 meter piece of this cable would cost over $3000, probably not worth it, or within the reach of most of us. I was fortunate enough to get a used pair for a very reasonable price.
Off-subject: The only criticism I have about these headphones is that a) they are head crushers, and b) they do not give the same amount of spatial separation as some much lower-priced headphones. I have never heard the HD-800s, which have been consistently rated as the cat's meow to end all meows.
But I am happy with what i have.
