I compared Synergistic Tesla Acoustic Ref with the AZ Satori Shotgun, and found the Synergistic somewhat better balanced and more accurate overall. That said, however, I found the AZ to be an extremely fine sounding cable, with an excellent sense of imaging and a nice fullness to the sound. My only minor quibble was that in my system, I found the lower midrange/mid-upper bass region to be just a tad too much, to the extent that double basses seemingly sounded undistinguishable from lower registers of cellos. Albeit, different tastes for different folks. I could easily live with either of these two top quality cables.
