I bought 50m of this cable for an installation. For stage use you would need a more flexible cable but for to install it's absolutely superb, particularly given the price when compared to others' products. The jacket is matt black which helps it be discreet and crucially it terminates well; the insulation didn't shrink back when soldering on to it.
This is a good cable for permanent install. The foil shield isn't designed for applications where the cable is moved a lot, but a drain wire is easier to solder than a braided shield and the foil provides good shielding.
