OK, I'll vote and take the criticism that will likely follow.
In my opinion, the Elrod is the far superior product of the two. I've had both of those cables in my system on Aesthetix preamp and my cheap digital and the Elrod had less coloration, more linear top to bottom with fewer tonal balance errors. Signal to noise (apparent blackness) was near identical.
My biggest objection to the Shunyata was the midrange.
