Dr Morrow speaker cables are more insulation than copper.
The upgrade path proposed is nothing more than various levels of thickness. Just like audioquest, who admits that the best bang for the buck is the type 4, 15awg for $200. Not much different than Kimber, except that Kimber's chosen geometry has a true purpose for long runs.
On a budget, between easy pay for less copper and the good old fashion pure copper 12awg figure-8 or twisted at less than 1$ a foot, it make more sense to go with good old fashion. Skip the upgrade path and go with heavy gauge for peace of mind.
