I think the most important difference between Speltz and standard cables is that the Speltz cables have no insulation (beyond the coating of the wires) and no jacket.
A designer/modder friend of mine believes that the insulation and jacket found in standard cables smear the wave form, thereby introducing distortion into the signal. This is why Speltz cables often sound better than other cables.
He did a comparison of a number of different types of wire using the no-jacket and no-insulation method, including the wire Speltz uses, and found that high-grade copper Litz wire is clearly superior.
