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!
