My vintage RCA cables from 40 years ago that were interconnecting various Kenwood, Sanyo, Realistic and JVC components are doing the job with the actives. These cables may actually be older than 40 years because I scrounged them from friends' places. I spent some time re-routing them and now 60 Hz noise is gone.
