So I have other cables I just use and after use, between pre-amp and amp, amp gets my fault and I have a noise on the speakers. I did not look that said, it seems that this cable is unshielded this causes snoring, I also suppose that there is a shunt between two conductors. I did not use it on my turntable phono, as snoring, but that's OK with even more low-end cables.
A little disappointed, suddenly. I think especially that the construction is not followed or equivalent. What is very damaging.
