Kipduff, you had asked me a couple weeks ago about the integrity of magnet wire insulation. All I can say is that the modern stuff is so tough that I have not seen evidence of a short in a voice or field coil in many years, and never in a speaker run. On the 1930s RCA drivers the coils would fail sometimes from the ancient purple varnish insulation flaking off the wire.
Jeff mentioned running untwisted, spaced wire runs. I used to do this years ago, attaching runs of #28 to the ceiling with Scotch tape. I began using drill-twisted runs for convenience, but never made careful sonic comparisons.
As to current capacity, with 108 - 110 dB sensitive drivers the speaker wires will rarely see a watt of signal on peaks. I have noticed no limitations, only wide open transparent sound. Please give it a try and report back. There may be something to the idea of matching wire cross sections between output transformer secondary and voice coil, both of which feature long lengths of tiny wire.
Just imagine... if fine magnet wire were best, who would tell you? Certainly not the purveyors of garden hose speaker cables!
