Duelund conversion to DIY Helix Geometry Cabling

Williewonka@ what’s the influence of sound by the twisted neutral and ground”does a tighter twist over the live wires increase focus, air or timber of the ac cable.

I’ve been playing around with the helix design on my dc cables with some Input from granny and am very pleased with the results using leftover mundorf 18g silver gold and plain 16 g copper for the neutral rather then military spec silver plated copper cause that’s all I had laying around for now. 
My question is from those who have tried it what’s the sonic difference between mil spec silver plated and plain copper on neutral .

Thank you Steve I appreciate you sharing your experience and knowledge and hope to try some mil spec silver plated cable from take five audio one day,

Steve, how long of a neutral would you have on a dc cable 3 to 1 , 4 to 1 ?

thanks you

Williewonka

After reading this thread and your website several times I discovered the Jantzen wire for neutral was also recommended which I was able to find here in Vietnam, I’m an expat retired and you just don’t go down to a radio shack or order online and puff your item shows up in a couple of days it doesn’t work that way in s.e Asia and yes I agree with your description between the zip cord and quality wire. 
Regarding wire being wound counter clockwise doesn’t wire that has been soldered need to be broken in again ( thought I read that somewhere and it certainly sounds that way when I’ve done that in the past ) and re winding the wire would require break in again of at least 50 hrs.

Currently both dc cables have 96 hrs after installation of the Jantzen 16 g wire and are sounding very good indeed.

Thank you

@williwonka. Yesterday I made  a one meter power cable for my music server using 2x 14g solid core occ copper with each run in a Teflon tube slightly twisted. 1 x for each neutral and ground. Both 4 meter lengths of ground and neutral wrapped counter clockwise  together, pure copper plated gold spades were crimped and soldered. I used a well broken pair of furutech ncf plugs

With a little over 14 hrs on the cable I’m pleasantly surprised at the SQ. This was my first PC and it took a 3 hrs to complete. 
 

This cable replaced furutech sp 55 n cable and already shows better imaging and inner detail.

I have previously made a couple dc cables with your helix formula with good results.

@williewonka, in your experience with crimping and soldering how much time does the soldering require to sound its best. I believe I read in one of the topics here someone mentioned 350 hr. In my experience it’s not quite that long but a couple hundred hr.

@ williewonka, 

Im now thinking of making a pair of speaker cables and have a few questions.

For the live wire you’re stating live wire 2 x 14 solid and neutral wire 1 x 12 stranded. Why not 2 x 14 solid and 4 x the length rather then 2.5 don’t you want more coverage of the live wire. Shouldn’t live and neutral wires be the same size 2 x 14 yields a 11 g. Vs 1 x 12 g. 

Have you tried low mass spades ? 

Can I cover the speaker cables in a designer sheath to look more professional or does this affect the sound quality.

You guys are right the cables take a dive around 20 hrs before opening up nicely around 50 hrs I was about to yank them out but something kept catching my attention in the presentation, a naturalness I guess you could say.

Williewonka got it, thank you.

No problem williewonka,

Have you tried wrapping the live wire in copper mesh before winding the neutral and ground around it with the male side grounded?
 

would this increase capacitance or resistance effecting the dynamics.

The thought of wrapping the live with a copper wire mesh popped in my head but given the amount of work it will take I wanted some thoughts before I proceeded.

 

thanks ,

Williewonka, I believe you mentioned the Teflon tube to be 25-30% larger than the bare wire inside it, what effects does a larger Teflon tube have on the sound. 
 

i just finished building a new dc power cable using 2x 26g wires and the smallest Teflon tube I could find is probably a 10g .

5v powering a FMC been running this wire for months without issue, so far….

 

It’s wire from an Audioquest diamond usb cable I wasn’t using anymore..

Williewonka I’ve been playing around with this helix geometry for sometime now and have found what works best for me and that’s for PC powering source equipment I use 8 strands of 18 awg solid core pure Japanese copper in Teflon tubing for both live and neutral for a combined 9 awg. It’s not the awg so much has the number of conductors. I would like to use 20 awg solid but difficult to find here in Vietnam. For ground I use 2x 12 awg stranded. 
The main PC from wall to conditioner s 7x 14 awg in Teflon tubing for both live and neutral. 
I first tried 4 x 18 awg and 4 x 14 awg then 6 x 18 awg and 6 x 14 awg and each step gave me more of what the helix geometry is so good at.

I didn’t do this by chance but from studying how cables like Nordost Odin and Audioquest use multiple solid wires on both live and neutral.

I use Furutech Rhodium mini spades to connect with there Rhodium NCF plugs.

These are stunningly good cables for reasonable cost.

@williewonka I’ve posted on my systems page a version showing a PC, all be doing a new speaker cable next week and we’ll post them. 

Have you tried 4 wires on both and both L and N in Teflon tubing.
