My goal in sharing the helix design via my web site was to have other DIYer's run with it and try their own adaptions, which is exactly what you have done.
The information you have provided is valuable and I will certainly consider your findings when looking at a possible "next version"
Although I have not tried 2 x 24 gauge Helix IC, this is what I have tried...
- a few versions ago I used a single 24 gauge solid Silver wire in side a Teflon tube
- I then tried 20 gauge with teflon insulation and it sounded better.
- other DIYer's tried the 1mm (18 gauge) Mundorf Solid Silver/Gold wire in a cotton sleeve and it again improved the sound. So I then tried that
- Following that I tried the 18 gauge VH Audio copper and it was as good as the Mundorf Solid Silver.
- Then @grannyring tried the 2 x 18 gauge OCC copper from VH Audio and again the sound improved.
So that has been the more recent "evolution" of the current Helix IC.
It's been a real "team effort" that I could not possibly have accomplished alone.
But at this time, I am very happy with the IC's current design listed in this thread and right now I just need some time to just sit back and listen :-)
But I will keep your adaptions in mind for future versions :-)
Perhaps someone would like to try @mawe's adaptions?
- be sure post your findings here please.
Again - many thanks for sharing your adaptions - it's great that people are trying different things with the Helix design.
