Duelund conversion to DIY Helix Geometry Cabling

I have not found a Bulk Supplier of the Wire, as D.U.C.C which is the name used when found in a Cable.

Mitsubishi has a Ref Code for the Wire which I believe is the same wire. I have never found a Bulk Buy option whilst researching this Ref Code either.

My D.U.C.C Wire has been purchased as Mitsubishi D.U.C.C Cable.

Note: D.U.C.C Wire has the capability to underpin the presentation with a hint of Richness, this really suits a Vocal, but in one system during it in use as a demonstration against a Pure Silver Wire Cable, one attendee was claiming there was a sound being produced where the Female Vocal sounded slightly nasal.

It might be worth having a Trial with a Cable prior to fully committing to the Purchase. I myself have not had a better Cable between CDP>DAC, this has superseded, OCC, PC TripleC, and a Mapleshade Ribbon.

SAEC SL 5000 Cable has PC Triple C Wire and if the construction is looked into, a Helix Twist can be identified as being used.

The above is guidance to a Manufacturer, not as suggestion the SAEC Cable is a mimic of this Cable construction type.  

@mikerubin The XR 5000 is the XLR version of this Cable.

"Beauty is in the eye of the beholder"

I am sure there are others that can't but help admiring their handy work, and the quality seen for the producing a uniform 'Helix Configuration' .

@camrector Have you considered PC Triple C Wire.

I have wore on my sleeve, my being an advocate of the Wire Type within this Thread and on this forum on quite a few occasions.

I own it as Purchased  Cable and as the Wire only. It is owned as both Solid and Stranded, and I also own a length of PC Triple C / EX, that is quite expensive.

There is a Helix Build using Triple C within this thread, a report on the impression mase is available from the end user.

In my own HiFi community in the UK, my loaning of the the wire has made a big impression, where a growing in number are superseding the use of OCC Copper and Silver for the Triple C.

Some who have experienced it in comparison to OCC, and are in possession of systems claimed to be very resolving, are classing the impression made as Night/Day as a betterment. 

As a result of my loan of Triple C, and growing in number converts, the wire has caused a stimulus and curiosity to those that are introduced to it.

The Wire is now found in use as PC, Hook Up Wire, Interconnects, Cart' Tags, Speaker Internal and Speaker Cables and it is also now used as a Continuous Wand Wire within a Tonearm as a upgrade by a renowned UK based Tonearm designer / builder. 

The same TA builder has intimated, they may send a Cart' to a rebuild service to have the Coils wound in Triple C, when the suitable wire is discovered. 

I hope you become curious and make inroads to try out this alternative wire option. 

@camrector I've added 2 Links to my previous post, I had a search for you.

From my knowledge XLR's are both Low Mass and Low Eddy.

Low Eddy RCA's will be found in WBT ranges.

I've done a lot over the years to produce a system that resolves the embedded info, in a way I believe the recording engineer intended it to be heard as sound and effect when replayed. 

PC Triple C was another material when introduced, that offered a new capability to reinforce the experience as having been increased in honesty.     

@camrector My ears are pricked up, my attention is on you 🤓

Firstly the Cable you have referred to has sort of vanished, it is periodically showing for sale.

It is this Rtiple C cable remaining in the form purchased, that superseded my use of Mapleshade Clearview Double Helix Speaker Cable used between 845 Monoblock Amp’s and ESL Speakers. Note: This Triple C did take about two hours of usage before it become the Cable that shamed the M’shade.

A few weeks of revert back to M’shade and return to Triple C, left the M’shades seemingly inferior and very veiled and muddy as a description.

Here’s the crazier side of it, approx’ three years previous, a Speaker Cable Bake Off was arranged at a home with another Valve Power Amp’ > ESL. There was from recollection approx’ £7K New Cables in the line up, of which the most expensive was a £1.5K pair.

The final selection and ones that all in attendance were unanimous as being the better Cable on the day was a True Silver @ £700 per pair.

The Wild Card M’shades were then used as the comparison, and the whole room fell apart on which was the better. The individual buying Cables would have bought the M’shades if they were a UK Cable and not a Import.

I learnt later that True Silvers have a origin from the US.

The wonder is what will the Triple C have done on this day if available at the time.

As for mass in a Connector, this is one very well flogged to death within my HiFi social circle.

Low Mass is now proven to be wanting when compared to Low Eddy.

Low Eddy RCA’s as a Cable Termination and Chassis Mount, will most likely knock you out of the Ball Park, well it did for myself anyway.

I thought I understood the envelope of a note or vocal, I do now as a result of being introduced to Low Eddy on a SS System, in a way that I have never experienced before.

I've had a search and discovered the two options, the Reference II is I believe 1.8mm and SPV 0.9mm Diameter.

Both are a rare discovery at this price, matching pricing around COVID times.

The Beauty of what is happening with the intentions within a Thread Like this, is that when it comes to base materials there is no holds barred, but plenty of experience suggesting a particular method and expected results.

If the PC Triple C is able to be sourced as a materials to meet a particular recommended method, this will add to the options already on the table for the Helix Design.

I really Look forward to all the build reports that are to steadily be reported back on.

My own requirements may be changing as my original plan to go Balanced was to have a Short Helix Cable external to the Amps Chassis, as the Pre Amp Out and Power Amp In.

A design has now been presented where the Pre and Power might work like an integrated with the Pre Amp Coupled to the Power Amps Chassis.

This method has lead me to thinking there is the potential to have a Hard Wire connection for the Pre's Out, with a Helix Design Cable concealed within the Power Amp. The individuals doing the work are yet to be presented with this as an idea.

@williewonka You are absolutely correct to encourage protection of a Warranty.

These small sureties are valuable to have available.

I myself am long overdue on any security on offer.

All individuals involved in the planning and application  are EE's either from the  original build and willing to add to their design or the EE behind the new designs to be put in place.

Double ,Helix ,has a place in this, I thinks anyways

In relation to RCA connectors, I have been very familiar with the Low Mass models from the Brands commonly selected.

My being an advocate took on a profound shift in a alternate way of thinking when having experienced Low Eddy design RCA's as both Cable Termination and Chassis Mounted with PC Triple C Wire.

I have no doubts in my suggesting, strongly suggesting, these connector types used as experienced by myself, will enable any Cable in use, to offer its most optimised performance.  

@lemonhaze There is a lot of info to be found on the Web about RCA's with a design that is not just Low Mass but Low Eddy as well.

The descriptions mainly relate to RCA's as I am believing XLR's are a inherently Low Eddy design, I might be incorrect on the XLR description.

For the record, my experience of this change of Connector, has been exclusive to a Tonearm > Phonostage > Power Amp, with SAEC SL 5000 Cable.

I was demo'd the WBT Low Eddy connectors in place against the standard supplied connectors on the Cable.

The System owner also the designer/builder of the Tonearm, had prior to my demo's given, used their long-time owned Copper KLE Harmony and come to the place where the Low Eddy type from WBT was to Supersede them in use.                This became very apparent when the Chassis RCA was also to become a Low Eddy connection.

I can say the system used is one I am very familiar with and is very revealing, due to it detail resolving capabilities. 

This system has on occasion introduced me to the perception of Envelope, not many systems are capable of creating this perception.

The use of Low Eddy connectors as suggested, reinforced in a discernible manner, that the perception of Envelope being manifested was seemingly tangible.

Unfortunately for the type that really does like to think their system dedicated to replaying recorded has substantial capabilities at resolving information embedded by the recording engineer, such a indelible impression made by the perception of Envelope become another plateau to be ascended to.   

For myself today, when considering my next steps, Low Eddy, is the top of the list when it comes to creating an interface between Umbilical Cable and Device.       

@williewonka As stated there is much info to be found on the Web where Low Eddy is the description about RCA Phono Connector Types.

The Brand I have experienced and the same Brand that has restructured my way forward in relation to RCA connectors, is WBT Low Eddy, used on both Cable and Chassis.

There are a few models from WBT, I will make an inquiry to get the Ref No'.

If you would like to try a PC Triple C Wire Cable, send me a PM, I have a Stock of this for my Cables yet to be produced. 

@williewonka you asked "Any Thoughts? Steve"

I know that there is a spirit of investigation on this thread and there will be discoveries made as a incremental way forward and quite possibly backwoods.

I introduced a individual to PC Triple C, they have not looked back, they also know my interest in Helix Design and FINEMET as an alternative to Ferrite.

With all the good things already happened they bought into SAEC SL 5000 Cables, which I feel ticks boxes in relation to my own interests shared. .

The Supplied RCA Connectors were compared to KLE RCA's and KLE were the chosen type.

The investigative mind did not rest and other RCA's were considered of which WBT Low Eddy was a selection.  

This RCA was the new chosen design and the idea to couple it to a purpose produced same design interface Connector took on a must try out on a list.

This is where I was introduced to the evolving use of SL 5000 CCC > OEM RCA  and SL 5000 CCC > WBT's. ( I missed the period of KLE's being in use)

I trust the system owners judgement and I know the system very well.

The WBT's used as a the Cable Termination and on Chassis has changed my whole thought process about what can be achieved and what really can be achieved, the impression left is very good.

Maybe it is just one of those leaps one has to take, there is also the analogy where if nothing is ventured nothing is gained.
