second, I dont seem to have trouble fitting heatshrink and (not techflex, that just feels cheap and plastic-like), nylon multifilament and yes it all fits into that tiny neutrik connector, its a magic trick I do, wanna see how?


Few simple rules for those of us who are wanting to learn:

1. 8 wires can fit in a tiny neutrik connector
2. however you are building your cable, unless you can cross signals at a 90 degree angle (or there abouts atleast), if you can't, then dont cross them. plain and simple.
3. if braiding, braid it as loose as you possibly can. a cable is not alike a woman, you want it loose as a goose, to allow air dielectrics as well as to keep the wires from touching one another as little as possible.
4. Upon finishing your cable, don't immediately listen to death metal, or R&B/rap and then say that you cannot hear a difference, no duh you can't, thats not hi-fi audio to begin with. put on some classical/jazz or classic rock for that matter.


if I'm coming off arogant at all I apologize, posts like the one I quote get on my nerves and its 3am so Im tired enough to express it.



So it was 3am and I forgive you

My actual point was that if someone is trying to sell/make a wrongly made cable and call it "litz braid", before this kind of bubble bursting thread then he is just ignorant because he doesn't know he's doing it wrong (since everybody and his sister makes it same way).

But now, with a thread like this, where the flaw/blunt mistake was discovered if I'd try to make a cable that way and call it "litz braid" I'd be liying to myself. That's still fine though, ppl do it everyday. But the moment I try to sell it saying "it's litz braided", I'd be a scammer. The guy who invented/suggested this Litz braid made it with a specific configuration for a specific purpose. If I do it completley wrong, it ceases to be "litz braid" and becomes just a "braid".

But i'm not really flaming anyone (just the way I talk). Its easy to understand how this mistake accured and turned into a fasion. Not to many ppl readed that faq on chimera lab's page. Most folks (meself included) just googled/was reffered by someone else to it for instructions on how to do this particular braid. And on that page he just braids one of the channels of RCA. So peeps just picked it up from there and instead of making an 8 conductor stereo cable they've made a stereo cable out of 4 conductor MONO configuration. Relatively simple to do, relatively fast to do and relatively economical! So why the hell not? Well why not besides the fact that you're doing it wrong and by trying to get some work-around-shielding get some crosstalk party with it.

This is also why not to many ppl jumping all over this thread screaming OMG you're right/OMG you're wrong. It's a little embarrasing. Peeps repeated the same mistake years upon years.

As for the "neutrik magic"

yeah I know It can be done, it's just that I never tried to fit two separate 4 conductor braids in there.. Although the plug might be fine, especialy if drilled, but I actually thought heatshrinking the two braids seperatly and entierly so that they won't have any contact with eachother and then some nylon sleeve over them.. I imagine it should work. Just need a huge sleeve... two techflex runs ander the nylon sleeve would be easier to work with, I guess.

That config might be good for interconnects but I wonder if shielding is even that needed in a hedphone cable. If not, I could get away with just 4-conductors-twisted-in pairs-and-heatshrinked-seperatly combo...

EDIT: J.D.N@ I'd really like to think that this Starquad Canare I used yesterday for my porta's is perfectly fine (since I freaking love that thing) but les_garten put doubts in me..

But then if I got fsma's idea right, starquad used this way should be fine (correct me if I'm wrong).
Personaly I still feel it's not a good idea to run two signals in such a close proximity to each other, paralel or not..

I would say be a little patient. I'll shoot some pix of the cable I have. I "think" i can get it in a Furutech or neutrik. Guitar Center Roadies looked at my wire and plug and said it would go in there with some work and technique.

You can't drill out the one's I've seen because you would take the threads out.

The Chimera site perpetuated a problem based on pure happenstance. When I talked to the guy about his cable technique, after some discussion he finally got something across to me. This is very important, because here is where a lot of the problems started.

On his instructions, you see left and right labels. Everybody looked at that and thought it meant Left and Right Channels. I thought that was what he meant. I kept coming back to how that was screwing up the twist and what not. Pay attention to the next part.

He finally got it across to me that that was labeling L and R sides of the vise holding the Cable!!! It's for starting reference!! Has nothing to do with signale channels. His braid is meant to scale to 4/4 8/8 or 24 and 24. He's just showing a braid for a +/- wireset.

That's where the FAQ question/answer came in. I talked with him at length about making a Stereo Cable and he was confused about why anyone would do that!!

His L/R labels could have been just as easily A and B if that's how we labeled our hands. DOESN'T HAVE ANYTHING TO DO WITH CHANNELS!!

He locks his wire ends in a vise to start the twist, you divide them up into L and R. When all the Lefts are back on the Left side you have completed a set!

He also did the Positives on the inside and the negatives on the outside which confuses the hell out of folks who don't understand that it has nothing to do with Stereo.

To recap:


1. The litz-braiding technique uses 4-wires per channel.

Proper litz-braided mono cable:

- 4-wire braid (channel 1): --{1-, 1+, G+, G-}--

Proper litz-braided stereo cable:

- 4-wire braid (channel 1): --{1-, 1+, G+, G-}--
- 4-wire braid (channel 2): --{2-, 2+, G+, G-}--

Naturally, grounds aren't considered separately with this technique because, with the litz braid, the grounds are integrated into each channel; additionally, the grounds of all channels are linked at the beginning and end of the cable.


2. No hard evidence has (yet) been provided to prove the hypothesis that proper litz-braiding has a practical benefit.

Maybe a discussion could be started in the sound science forum? From what I've read, crosstalk can be measured objectively; surely someone in that forum has the proper equipment and would be willing to test the hypothesis. Personally, I'd really like to see the results.


3. Regardless, improper litz-braiding: a) is misleading, b) can never be more than a gimmick, and c) may even be detrimental.

Combining wires from different channels in the same braid doesn't have any positive effect (because it doesn't fit the hypothesis behind litz braiding's supposed benefits); and, it may even introduce the opportunity for problems (if the improper braid is assumed to eliminate/reduce the need for shielding between the channels).



You may want to re-read since you missed everything.

I apologize peyotero, my bad.

Yes, I agree with you completely on that matter.

I easily fit 8 wires into any connector, listening using furutech FP-704 as I'm typing this, except there's 16 wires, but I won't get into that. I'd post pics but that would be against commercial posting policies.

Les_gartens: exactly, glad some are honestly getting it.

And no, actually, shielding is not needed with this style of braiding IF and only if, it is done correctly. multiple conductors of each pos and neg signal, braided in that specific fasion, starting and ending with negatives on outside, positives on inside, as this creates a shielding of EMI and RF rejection around the cable as the wavelength passes through it.

les_garten@ when you post that pic of your cable. plz plz plz resize it. Thanks!

You don't like those Pix?

it's just if they are to large they break the thread normal size and it's hard to read and respond.



Yeah, I post'em that size when I'm too lazy to do a Batch resize.

I'm with you on everything else, but this statement is pretty lame. I'm sure hi-fi appropriate recordings can probably be found in most genres, and genre has nothing to do with something being hi-fi or not. Sure, you're more likely to get "hi-fi" recordings in the classical genre, but that doesn't preclude other genres from having hi-fi appropriate recordings.

I would say separating Layers of Grunge is always a good thing and the intended goal!

Yup. Some stuff from Tool for instance... or The liquid Tension Experiment ***

I think maybe he was thinking was some rock and rap songs have a lot going on so it can be hard to destiguish subtle changes in sound. I also agree with your statement there should be quality recordings of every kind of music available.
