Duelund conversion to DIY Helix Geometry Cabling

@mbolek It took almost six months for a package to arrive that I purchased from Australia, there may be a pleasant surprise turn up.

I do believe that a XLR is a low mass connector and the Eddy Effect is reduced due to this.

As you are an EE, the discussion seen in an old thread I have seen, where a method is proposed for producing connections that are said to be Low Mass.

The Link will show the discussions and selected parts for producing the method from the era, there may be a variant as an option today.

I am without doubt the improved impact on what I was experiencing is due to the choices made for the connection.

This was not a veil had been lifted moment, each Cable was appearing equal in Soundstage Depth and Width, and how a insight to a recording was being perceived, each Cable was able to deliver with a very similar presentation for the overall performance.

The difference was how the Note and Vocal took on a Shaping of the Envelope, the Cable with the Low Eddy RCA Termination, when connected to the Low Eddy RCA chassis mount connector showed a substantial and notable improvement in this area of the presentation. 

Does having the CCC Wire running through the Analogue Source Signal Path contribute to the effect, I can not say, but it does contribute to the perceived purity that is present in comparison to other used signal wires.

@mbolek RE: 

I have tried many cables with this orientation and really never could tell a difference.

Not sure what you mean by "this orientation"

• are your referring to the rwo stranded live and neutral wires
• or the bare wire inside teflon tube ?

I recently listened to a Buchardt WiSA system.  No cables...sounded awesome.

The days are numbered...

I agree - I have several Bluesound products. Their Pulse speakers employ a similar approach with imbedded amplifier and streaming hardware/software

• You can pair the epsakers into a L/R configuration for 2 channel operation
• no cables and they sound very good

It's only a matter of time before this becomes the accepted norm among speaker manufacturers

But oyu still need a good power cable 😀

• sometyhing Buchardt omit from showing in the photo's of their products

@ketchup RE: 

What direction should the hot pairs be twisted and what direction should the grounds be twisted around them?

I agree with the answer @mbolek provided.

I would say that the positive/line conductor should be twisted in the opposite direction of the negative/return conductors.

@williewonka like this?

Keep in mind that I'll have double grounds, though.

@ketchup - I was thinkging about the double shotgun approach...where

1. you have a Live conductor
   • consisting of two wires twisted together
     • in a right hand twist
     • one complete twist every inch
2. you have a neutral conductor
   • consisting of two wires twisted together
     • ​in a left hand twist
     • ​​one complete twist every inch
3. you then twist the neutral conductor and the live conductor together
   • in a more relaxed right hand twist
   • about one twist every 3"-4"
4. and then insert that sub-assembly into the double helix coil

Hope that clarifies things
