@sns , good for you! DIY is the way to go with cables. The best cable is the shortest one and you never get the shortest one with commercial cables. There is first class wire and connectors available, as good as or better than what is being used commercially. The only thing missing is the fancy sheath and the slick marketing.
Service a The Cable Company is excellent but, there is also excellent service elsewhere. Upscale Audio, Elusive Disc and Galen Carol are companies that also stand out in my experience.
