NEO by Oyaide d+ RCA (Class A) – Hi-Speed and Durable Digital Cable for DJ’s, Musicians and Producers

So i brought these from another vendor, unfortunately they picked up RFI interference, so had a nice hum on my system, just putting a cheep cable with decent shielding fixed this problem. the thing is i brought these due the the quality of the copper in this cable, to help with sound quality, but if its shielding is not up to the job, there is not point.I was using these as interconnects between my dad and amp at home, i would be really worried if was using them at venues for live sound and i was getting hum.
