The straightforward test is to make up an RCA interconnect cable from the wire in question. Put it between a source and a line stage on one channel and mute the other channel. Listen to a segment of a recording, then reverse the test cable and listen to the same segment.
One direction should sound warmer and the other brighter. Good male vocal recordings are useful for distinguishing the directional effect.
If you prefer the sound of one direction, then make your final cables from the same wire taken from the spool in that direction.
My opinion is that neither direction is accurate. This leaves two methods to cancel the first-order directional effects: either parallel wires with opposite directions for each pole, or divide each wire in half and reverse one of the halves. The parallel wire approach opens up additional resonance modes among the parallel wires, while the divide-and-reverse approach creates an additional joint. My present speaker cables are made with the parallel approach, but I think good solder joints and Teflon insulation would allow the divide-and-reverse approach to be more revealing.
