My Suggestion is not to rush in on a purchase of a Cable from a Branded Supplier.
You can learn a lot by trying out variants of the surface areas of the Wire, or strands and strand thickness used to produce the wire.
A wire produced to the Spec' H07RN-F, can be bought from many locations at very small monies, the most expensive cost to be incurred at the off set only need be good quality connectors (preferably copper with Gold Plating)
The link suggests the Cable can be found for as little as £00.60p per metre (39").
Once it is determined which gauge works best with a device, then only does it seem to make sense that similar gauge wire is sought out from the Brands with the additional methods used for the construction.
Also avoid being fooled into thinking, a screened cables is the most important of the considerations, many of the Power Cables that have I know about, through being in communication with others carrying out trials on Power Cables and have discovered the ones that have been thoroughly impressive are unscreened.
Screening/Exotic Screening all add cost, the more recognised the Brand, the larger the premium added to have their Screened Cable.
