I own both Satori and Au24, and the Au24 is my preference (on Thiel floorstanders similar in size to 803's, which as I mentioned above cannot be biwired). Satori is a warmer, "fatter" sounding cable, but IMO is not as fast or neutral as Au24. Au24 has excellent, tactile bass, though it doesn't roll off the highs to make it seem like more than it is. I enjoy the Satori, but to me the Au24 is ultimately more transparent and natural sounding. I also didn't find that Satori gave a deeper soundstage -- if anything, it's more of a "they are here" cable, the Au24 more "you are there".
