There’s plenty of snake oil in the cable business, and plenty of good value up until a quality threshold is reached. The law of diminishing returns comes into play here. Take speaker cables for example. You don’t need to spend hundreds of dollars per foot to realize excellent performance. I’ve been using Monster Standard 12AWG cable in a bi-amp setup with a pair of vintage NAD integrated amplifiers (3025i and 3225PE), and I’m very happy with the results. These cables didn’t cost a fortune, heck, they only cost about $100 not including the Monster banana plugs that cost another $60. The results are there, and I’m happy. I bet most other people would be too.
