I have Audience Au24SE speaker cables and RCA interconnects in my system. I'm also using their Studio One jumpers. The Au24SE's are, of course, an older version of these cables but I'm very pleased with them and not in any hurry to upgrade. Previous cables included Cardas Golden Reference, Clarus Aqua, and Analysis Plus Big Silver Ovals. The Audience cables offer me so much more of what I want to hear: richness without compromising detail and a quality that I especially appreciate: "composure," (for lack of a better word). What I mean by this is that there's a controlled presentation up and down the frequency spectrum that doesn't descend into harshness or brashness when the music gets dense or complicated. My previous cables didn't accomplish this anywhere near to the extent that the Audience cables do.
I've seen the Au24SE speaker cables used for under 1K (though this is for 1M lengths) and the current Au24SX ones going for between $1500 and $2000. (There's currently a 3M pair of these for sale on the "other" site for just under 2K).
Hope you find this helpful.
