I had both cables. The AZ Satori Shotgun and Accelerator.
AZ is a very good cable. But Accelerator is better.
Here is the summary of 2 cables in my system:
AZ - highs are sweet, yet detailed. Midrange is a bit grainy(only realized in comparison). Bass is deep and powerful but not as controlled and as a result tends to be a bit fat, bloaty and lacks a bit of speed. Imaging is very precise. Soundstage is deep and wide with a good height. Soundstaging is this cable's strength.
SR Tesla Accelerator - Highs are more detailed than the AZ but still within reason and never get harsh. Mids are crystal clear. More air in the soundstage and better separation. Not grainy as the AZ is in the mids. Sibilants sound much more natural with this cable. Bass is very deep, tuneful and provides a solid foundation. Imaging is as precise or better than AZ, soundstaging just as good. Overall a faster, more natural, dynamic and open sounding cable with improvements over AZ in any meaninigful area.
It is also thinner, has active shielding, very flexible.
AZ may be better priced used. Accelerators may be hard to come by on the used market. However, they are a bit over $1k new for 8ft.
Both cables are excellent but my preference would be towards SR Tesla Accelerator. I just found this cable to be more real sounding than AZ Satori Shotgun.
Good luck.
