Depends on budget and if you solder. No solder, low budget, I would get Monoprice (direct or Amazon) or Talent (from Parts Express), maybe pig hog if they will be treated roughly in garage. Unlimited budget, WBC with Canare and Neutrik. Solder skills, maybe make something like the WBC using
@Wayne A. Pflughaupt 's online tutorial. I use his process with Type E silver plated aircraft cable wrapped and dressed with shrink wrap and techflex or paracord sleeving. I like the Neutrik gold TRS and XLR connectors and the Amphenol RCAs, but I will probably try Neutrik RCAs at some piont. There is probably no performance advantage of the cable I use over Canare. I just like it because I worked with it on military helicopters when I was young.
