I can tell you, the Furutech offerings are top notch. Let’s face it, they build stuff for everyone. It’s like Ferrari suppling engines to F1. What some teams do with those engines is better than others. Point is, you can get some VERY good cabling in “bulk”. But, it’s still not cheap. Then you have your terminations, then time. Power cables are probably the “easiest” to do well. For the most part, I buy power cables. I’ve built a couple, but overall I prefer to buy them. Check out Audio Art and Audio Sensibility both have excellent products that are not outrageously expensive. There are plenty others.
