For speaker cable that is either 'normal' side-by-side conductors or loose axial twist, inductive and capacitive reactance can be ignored. Both values are simply way to small to have any audible consequence when considered as part of the amplifier / loudspeaker circuit.

Only speaker cables with 'odd' conductor geometries (spaced, woven) will the reactance possibly have some audible effect depending on length of cable used and loudspeaker impedance.

Thus, for most 'normal' speaker cable, provided the loop resistance of the speaker cable is less than 2% of minimum loudspeaker impedance, we have electrical equivalence which translates into sounding the same. Even around 5% to 10%. I believe Peter Walker first suggested the latter figure for Quad equipment.

I did read Paul Millers article. The chapter in the book I linked to (which can be downloaded as a .rar file) is more understood *in my opinion*. The so-called five percent rule, which covers what I've said above in more detail can be read here.
