A loose twist will not affect capacitance and inductance very much, and would be more beneficial for flexible routing of the cable than for noise cancellation purposes. Capacitance as a cable issue affects high frequency roll-off. Close coupling of the two conductors without any gaps along the entire length of a simple DIY twisted pair speaker cable would be a better option, IME.

@Duster...Thanks again! Am I correct in saying that close coupling of the two conductors would reduce capacitance which in turn could prevent any HF roll off from occurring? Thanks.
Actually, close coupling of the two conductors will better optimize the capacitance and inductance of a twisted pair while providing effective noise cancellation. What application are you concerned about speaker cable capacitance? Does your particular power amplifier oscillate when high capacitance speaker cables are used? Inductance tends to be a bigger issue for speaker cables, not capacitance which tends to be a bigger issue for line-level interconnects.
@Duster. Actually ... my goal is to achieve HF rolloff. Read somewhere that "twisting" the -/+ conductors together could result in a lower capacitance. I also recall having read that HF rolloff could occur as capacitance goes up. I didn't go as far as researching the effects of inductance. Speaker cable I am trying now is the duelund with 3 other interconnects...one of them being the belden 8402. I did have the -/+ conductors separate initially and now loosely twisted. Loosely twisted did yield somewhat a brighter presentation...but I did switch interconnects around too. Am not tech inclined ...:(. I know I should just go ahead and try all possible configurations. Guess I am being lazy as it's a pain in butt fiddling with cables around my rack and listening room due to layout. And get some education on the effects of capacitance on speaker cables.Thanks for your time and patience :)

If you are using a bare wire connection, a banana plug, or a brass base metal spade, the Xhadow Reference Spade should provide a more full-bodied tonality, and calm down the treble energy. Even though the Xhadow Reference Spade is silver plated, the base metal is pure copper, and like the Xhadow Precision RCA, the connector does not sound bright, to my ear. Priced at US$14.15 per pair (US$56.60 for a quantity of 8) including cryo treatment from Take Five Audio, it's probably the best bang for the buck premium speaker cable connector, IME.

@ Duster...Thanks again!
