Installing the Audience AU24 speaker cables in my Aerial 10T and McCormack DNA-2 Rev A amp combo, was easily the best cable upgrade I've encountered.
Some to many, including Stereophile's reviewer last August, claim the Au24 speaker cables to be preferable over the Valhalla speaker cables. I don't know if that is true.
Audience talks about lack of time-smear, low-eddy currents, etc. and I believe Audience actually discourages bi-wiring. I can say that I went from a bi-wired config to the Audience AU24 mono-wire config and have had no desire to go back to bi-wiring.
But it is amazing what bass frequencies sound like without the very common time-smear affect. Similar results were found in the mid and high frequencies as well. It cleaned up the bass so much so, that my subwoofer now sounded disjointed from the Aerials. Audience recommended I try their inexpensive Conductor ic for the sub. Which I did. Those results were also impressive and brought continuity between the sub and Aerials back.
I'm using the AU24's as mono-wires with their 6-inch jumpers and realized even better sonics when I also re-installed the Aerial bi-wire jumper straps into the mix along with Audience's 6-inch jumper cables.
In my experience, the AU24 speaker cables can be a bit amplifier dependent though so you'd want to ensure a 30 or 60 day audition period.
I forgot to mention that one channel of Au24 speaker cable is no thicker than your keyboard cable on your computer.
