I made my original pair of 16 strand and it took me 6-8 hours To make them, nit including the time i needed to find some rope.

I made a new pair a few months ago & it took 4-ish hours to make them and they look much nicer.




Making prototype interconnects has been more annoying tbh.
I've just finished a 3rd pair and I'm burning them in now.

Here's a pair after feeding a 1/4" cotton rope through them:



And the tight space to install the wiring...



It's gotten easier, but it's still a pain, and the raw cable loses ~45% of it's length with the rope inserted. 7 feet of raw cable produced 2x 2' cables...

I've come up with an interesting tweak that we're really happy with. The trick now will be finding some good quality & affordable RCA ends to use in the final product. Currently I've been using the Neutrik "Pro-Fi" ends as they were pretty good quality without being expensive.

I have more cable on the way, and Danny has several sample ends on their way for us to try out in the coming weeks.  :scratch:
(They likely won't be offered as DIY due to the pain they can be to make)

Check out the Viborg RCA connectors, which are exceptional (and inexpensive).

We have several RCA ends coming in we plan to try out from different manufacturers to see which version suites our needs best.

I just received a version of the cable hoping it would be easier to feed a rope through, and it is, but it's also ugly compared to the other style.  :duh:
so I've got another 10M of the original cable coming in about 3 weeks.

I used the KLE RCA connectors. They were great to work with. They have low mass connections for the wire and the soldering points are spaced apart nicely, making things simple to work with. Very tight connection to my amp and DAC as well. They also sound quite good to my ears as well.

Hey y’all, I have some 12 strand GR research speaker cables I built. These were made with tube connectors and silver/copper banana plugs. They measure about 9 feet each after construction.

I had about 2 feet of leftover speaker cable that I didn’t use and wanted to see how much length is added to the cable with the braiding technique. Turned out 26.5” braided, unwound and straightened was 30.5”,
about 115% of the length.
This makes my 9 foot pair about 10.5’.
I have some extra length in my set that I built in for possible setup location changes. Using cable risers adds a little more possible slack.
I’m wondering if it would make a noticeable difference in performance if I terminated one end with about 14” less cable (roughly 16” considering the braid.) Leaving 9’ cables rather than a 10.5’ pair
There are elements I feel that these cables are limiting my speakers sound in mostly treble and upper midrange presence and attack. I do only have about 25 hours play time on them and maybe only 10 since I set up my system after moving.
Sure there are other considerations that could be the culprit like power quality here or my room, but if this unnecessary length can rob performance I’d sure like to know.
I know this scenario can definitely effect performance with regularly constructed speaker cable, but I’ve no experience with cables designed like this, and in such a low gauge.

Oh, copper in teflon takes a long time to burn in.  At least 100 hours.  Don't judge them at all before then. 

You can make them shorter if you want to but it won't affect the sound much.

I recently moved too and when I got my system up it definitely sounded off.  I ran a brown noise track on repeat and let it play for a day and everything sounded better the next day.  I still had some speaker adjustments to work out which also helped a lot.  I wouldn’t worry about the cables too much.

As a follow p my post let me think about what could be affecting performance. Turned out my power cable was touching the wall twice and i placed some spacers there and wow.
Good to know on the burn in i guessed maybe more like 50. I did think that these were coated in polyethylene but I’m no expert on it. I do know the rope used in the center is cotton.
