I recently discovered some cables with a capacitance as low as 47pF/m. The cables are hand made by order and this is what the technician who build them told me when I asked him about the capacitance of this cables (this is a translation, sorry if there is some technical fault):
"The previous version had a Star Quad (4 twisted conductors) geometry with a common braided shield. The new one is a miniaturized version of the above: same metal, same insulation, same cotton filling, but being thinner I can use two separate conductors per channel, each with their own shield and each with positive and negative signal in braiding pair. By reducing the size I can use an additional wire for connecting the grounds, and thus the shielding of each tube is connected only at the end of the destination (male connector), and so the only effective capacitance is the one which occurs between the stranded conductors: 47pF/m, unlike the previous cable that´s about 50pF/m between conductors and 100pF/m between conductors and shield."
This cables are the most neutral and clean I ever had. I compared this cables with the AntiCables and found the AntiCables adding some kind of brilliance, same as Mani said. As a plus they are cheap. Now all my cables are made by this guy including the power cable for the NOS1 with an L shape connector which make it easier to route the interconnection cables without touching the power cord.
If anyone is interested in this cables PM to firstname.lastname@example.org. I´ll be glad to help.
