Before I talk about those, I'll talk about how it sound. When I was first given this, I was sceptical because it didn't look as good as Norne or Forza cable but I gave it a listen anyway. Well well I was very surprised on first listen at how smooth and lively it sounded. Bass is tauter and more pronounced than Forza Noir Hybrid HPC.
Then I learned that it is 1.8mm thick OFC Copper litz. Don't know what gauge. I was told how time consuming it is to strip it of it's covering and sleeving it with the fabric and then comes the even more time consuming part of braiding it. Finally soldering it. As for material and connectors, the choice is yours but basically the sonics comes from the cable material and solder workmanship.
So the expensive amount that you pay for a Norne cable comes from the time consuming workmanship. The material cost is but a fraction of the total cost. I have to start learning how to make my own cable. The TOTL prices of so called high end cables these days are outrageous. They are almost half the cost of Susvara.
Prior to this, I have always favoured a pure silver cable for Susvara. I was very surprised that I actually like how a well made pure copper cable sound. Forza Noir Hybrid HPC is a hybrid of silver and copper, as is the Susvara stock cable.
