the sssnake SK369M-06 Patchcable

Bought these for linking my patch bay to my audio interface. Right from the start I noticed a crackling in the audio when even slightly touching the cables, turns out the jacks were causing bad contacts. Cleaning the connectors with fine steel wool solved the problem, at least for now. Oxidation can cause this issue but it's not something I'd expect from brand new cables (even from cheap ones). Everything works fine now, I just don't know for how long. I might replace them with neutrik jacks in the future.
