To twist or keep separate


My prior system setup required 30 ft speaker cables but my new listening room allows me to get away with speaker cable runs of about 12 ft. My original cables were Kimber 4TC. Since I only now need 12 ft for the longest run, I cut the 30 ft lengths in half, terminated the ends,  and ran two identical length 15 ft lengths to the speakers (Triton 1r). Then I figured I'd terminate the extra lengths and double my run to the speakers so I now have 2 - 15 ft lengths of 4TC. I figure this essentially creates an 8TC cable which gives me more copper for the signal. Question is this; should I twist each pair of 4TC together simulating the Kimber construction or are the two 15 ft runs better kept apart to avoid any interaction?

I would not think it important to keep them together. Theses Kimbers are a woven design that’s meant to minimize the electrical field. The effectiveness of the weave may not be exactly 100%, but may be slightly negative overall or slightly positive...but this would be true for any length of 4TC. Therefore, if you twisted them together, I’m thinking there would be no cancellation of noise between wires of like charge as there would be between a negative conductor and positive conductor that were twisted.

If you’re running each 4TC as a separate positive or negative run, then it would be good I think to twist them as the noise-canceling effect of the weave will have been bypassed within each leg at that point, unless you twist them.

Elizabeth is correct in that I am not running 2 positive and 2 negative runs but rather just doubling up the normal connection with a second run. Guess I could give a listen both ways (twisted or run in parallel) and see if there's a difference. Cables are 30 years old and very well broken in but my new gear is still going thru break in. I'll give both methods a try after break in.

Elizabeth,
interesting idea you had about the rope however I can't imagine attempting to snake a 1/2" rope thru 15 ft of cable 4 times. You must have a lot of patience or very short runs.

Thanks all for the feedback.
