In Reply to: RE: Request for speaker cable recs, where to go from Kimber 4TC posted by Dave_K on March 23, 2015 at 15:32:06
New TC color coded white-clear is significantly improved. Cleaner, more dynamic, more extended.
As an DIY experiment, try puffing up your cables so that it forms a hollow. Helix. The increase in audio quality is shocking and the basis for upper line Kimber

I switched from the old blue-black to the new white-clear TC about 5 years ago. The new white-clear TC does sound a little clearer and more grain free. I am open to trying the puffing tweak. What diameter should I be aiming for with 4TC, and do you insert anything into the center to hold the shape?
I use 1-2 inch, 3-8 rope or plastic tubing.
Idea is to have wires cross at 90 degrees to each other. For experimentation, no need for fill.

So I tried it, puffing them up to approx 0.5" ID/0.75" OD. I did not insert a rope or tube, as I expected that the best sound would be obtained with no additional dielectric material. However, I found it a little hard to keep the diameter and shape perfectly consistent, so I might try again with rope.
The result was that top end seemed a little more open and detail was presented in a more delicate manner. They seem smoother, but with a small loss of microdynamics or attack. The overall sound might be a little lighter as well, but I'm not sure. In my system, it was a lateral move. I think with 8TC in my system, it would be more clearly an improvement. I might try that, or try the 4TC again with rope core.
Thanks again for the tip.
I suggest trying a cotton rope implemented as a resonance damping core, and as a former to keep the diameter and shape perfectly consistent. Don't be concerned about increasing dielectric involvement, since the core should do more good than harm. It would at least be a worthwhile audiophile experiment.
Duster
Unfortunately, you have to cut & spread the cable end to put the rope in, so they will have to be re-terminated and I don't have any spare crimp spades. I also couldn't find cotton rope locally in a large enough size. So I will have to order some connectors and rope. I'll post a new thread whenever I get around to trying again.
Dave-
have you tried Transparent?
Rather than plastic tubing, natural cotton rope implemented as a core will produce less dielectric involvement, and provide good resonance damping for litz wire designs prone to cable resonances. The core allows better control of inductance/magnetic fields, and improve the braided/woven helix-type speaker cables noise cancellation geometry.
over short lengths I eliminate any stuffing altogether. The Kimber is stiff enough to retain its shape as long as you don't step on it. Different colored rope looks cool though... and the plastic can make it look much more expensive than it really is, for those impressed by appearances
LOL....
Incidentally in some automotive installations puffing and then flattening the cable still yields audible improvement but a smaller physical presence.
Also a noticeable sonic difference can be had in the orientation of the twist. Using the right hand twist wires to carry positive signal ( like the thread on a normal screw), seems to "speed" up the sound, making dynamics seem quicker. Using the other helix for positive ( left hand thread)seems to " slow" things down. Just my observation...
YMMV
The right hand twist notion is intriguing, unclestu.
Can you tell by the photo which color wires are the right hand twist of the VH Audio CHeLA (Counter Helical Litz Array) speaker cable design?
TIA
Yeah> The blue helix is right hand twist an the white left.
Strange, you would think it shouldn't make a difference at all ( but the rule of the right hand butts his head in here).
Be interested in hearing your experience
