I've DM you re a build, but if thats not your cup of tea, another option if you're looking for a neutral cable, or what i'd consider neutral is the Atlas Zeno Headphone cable. I have one of these i used with IEMs and its lovely cable beautifully made with zero microphonics. Atlas use the same UPOCC mono crystal copper and its pretty good value at about £300 depending on length. They make them to order with connections and length you want. The sound characteristics of UPOCC copper are slightly warmer than neutral, but not overly so, an unlike similar oxygen free copper you still get a very airy and detailed presentation with really good treble and bass extension. UPOCC silver, contrary to popular belief is not a bright sounding wire, its actually extremely natural, smooth and just on the warm-side of neutral too. The benefit over the copper is that allows more detail through, improved seperation, layering and is more controlled and dynamic. Both partner extremely well with the Stellia, but its just down to how much you want to spend and diminishing returns are an inevitability. Strongly recommend listening to a few a before buying if you can. Personally, i love silver with the Stellia and the heavier the gauge the more performance you get.
