Keep Acoustic Zen or move on?

Stick with the acoustic zen. It's an excellent line of cables. I've been down the Audience road, and am very happy with my Acoustic Zen stuff. 

My experience with owning a full loom of cables (interconnect - power & speaker cables) is that 1 of those 3 types will be exceptional, while the other 2 are just average to above average. In the case of Acoustic Zen, I've found their speaker cables to be exceptional. I've challenged them with a handful of other brands (usually at higher prices) and the Acoustic Zen's have won easily every time.

Of course, Your Mileage May Vary; so, while it does not hurt to try something different, you should prepare yourself to be impressed!

Thanks gentlemen for the thoughtful responses.  Still thinking about cabling changes.  Working on slightly repositioning speakers to improve performance.   But, ugh, need to get some movers in as there is a heavy console with TV in the middle and this move will necessitate at least one longer powercord - and so it never seems to end, LOL.

Yes the AU24 weren’t as good as the Satori. But the Audience AU24SX or FrontRow (original) will be more open and more resolving than the AU24SE or Satori. 
I’ve owned Satori, Satori Shogun, and heard Absolute. New Audience SX or FrontRow are better cables if you are looking for more details but still vivid and natural midrange. AZ are really nice cables but the two Audience models are a few steps above.
