Duelund conversion to DIY Helix Geometry Cabling


I have been an avid user of the Duelund cabling for over two years now and have used them exclusively in my system with great results. I have built many for friends and have used a full loom of interconnects, speaker cables, power cords and an extensive wiring modification for a previously owned balanced power conditioner utilizing Duelund 600V PolyCast wiring which was transformative. My cabling desires can be a little addictive as I have owned and evaluated 40+ brands of cabling costing more than an entire stereo system!

Over the past six months I stumbled upon a thread here on Audiogon in regards to a Helix designed cabling and as you probably already know, I just had to look a little deeper into this cable design…After a month of studying and sourcing parts, I decided to reach out to the designer/architect, Williewonka who gave more insights and philosophy on how the cable came into existence.

That conversation got the ball rolling in converting one of my KLE Duelund interconnects to Steve’s Helix designed which only entailed replacing the neutral with a Mil-Spec 16 AWG silver-plated copper wire with the neural wire being 3 times longer than the signal wire and of course the “Coiling” of the neutral wire : )

After the modification was complete, I was not sure what to expect from the Helix cabling but I was quite shocked with the results with “ZERO” burn-in time…The sound stage became much wider/deeper with a much tighter/focused image and clarity/transparency is like nothing I have ever heard in any cabling regardless of cost. In fact, I just sold a full loom of a commercially designed Helix Cable that’s renowned around the world and has more direct sale than any cable manufacturer; these $200 DIY Helix Cables walked all over them…

I believe you will hear the same results as I have and have heard back from friends who have already modified their Duelunds with the same results; WOW! Remember the cables will need 200+ hours to burn-in and settle into your system. My system is now 90% DIY Helix to include IC, SC, PC and Coax with each cabling adding its beauty of an organic and natural presentation that draws you into the fabric of the music.

You can tailor the sound of your cables using Duelund, Mundorf silver/1% gold, the outstanding Vh Audio OCC Solid Copper or Silver with Airlok Insulation or your favorite wiring and you can change it at any time…

Haven't visited this thread in a while so unaware of IC recipe. I will have to build some double barrel IC's with the vh audio airlock.
I built my first Helix pc perhaps a year ago, easily heard upgrade over Shunyata Python and Vh audio Airsines I was using. At this point I'm using Helix pc on every major component in system, everyone added only further upgrades sound quality. Originally, I was using Duelund AC rated on hot, started noticing a bit of darkening, rounded bass, highs rolled. Replaced Duelund with Vh audio airlock, lightened up on bass, opened up top end a bit, sound a bit more refined, greater resolution.

Whether built with Duelund or Airlock, the most noticeable improvement heard over many other pc's I've tried over the years is the amazing transparency, never heard pc's sound so open. A couple of differences in my recipe are cryo versions of Parts connexion connex ac plugs and bare wire attachment at ac plug. I use two runs of airlock in source components, four runs for tube amps.

Thanks to Steve for a really great diy recipe, easily best diy recipe for anything audio related I've experienced in many a year in audio. Having auditioned many high end pcs over the years, I can't really recall any I wanted to use on entire system. These are so natural in timbre, tonality, really very little coloration.
Received a Helix power cord today, constructed as follows:

6ft with 20amp Furutech CF IEC and a 15amp Male CF (Like Furutech)
5 Strands of Copper Solid Core VH Audio. Black Wire Coil with Single White Ground.

Plugs from a Maestro Duplex into an Inakustik AC-3500P, the main PC for my rig.

Sound from top to bottom is even quieter and more startlingly real.

These Helix cables are seriously off the hook.

@rx8man 

It will get much better after 200+ hours and you will begin to hear what they are capable of in the 72+ hour range. Run them 24/7 for a few weeks...

@sns and @rx8man - thanks very much for posting your helix experience - it’s great to hear what others are trying and to see that the helix design is getting some very positive feedback from even more Audiogon members.

But wait - there is another Power Cord Update !!!
- you just had to know this one was coming :-)

As per my posting above RE: my 11 ft extension cable
- I tried the same modification on the power cable from the 11 ft extension cable to my amp
- so now I have 12 gauge solid core Neotech OCC copper from the outlet to my amp

I took the same approach
- I replaced the 4 strands of 28 gauge Vh Audio solid copper with a single strand of the 12 gauge Neotech wire.
- I removed the teflon insulation and replaced it with Cotton sleeve (see previous post)

This really opened up the performance of my Bryston B135 integrated amp to new levels of detail
- larger image in all dimensions
- more focused image
- better low end control and details
- improved clarity
- better dynamics

The improvements were barely noticeable immediately, but really started to improve after about 2 days 24/7 playback (I don’t have a burner)

The PC seemed to have settled after about 5 days playing - I haven’t noticed any further improvement

However - i am not sure this level of improvement will be achieved using separates, since I believe most of these improvements are achieved within the pre-amp section of the B135 and not so much in the two power amps.

FYI...
- the B135 is in fact three separate amplifiers in a single case
- each has it’s own power supply (3 separate transformers, smoothing capacitors etc...)

I believe @wig is updating one of his power cables to this latest development - I look forward to reading his feedback

I am planning the same update to the power cable that attaches the extension cable to the power distribution box, which distributes power to my two source components.

Just waiting on the Neotech wire from the UK - I will post my findings in about 2-3 of weeks.

It will be very interesting :-)

Regards - Steve
