Great cables! I haven't had the best experience in the world with Shure cables (they tend to bend and bend too easily and are very difficult to train), and these are high quality, delicate cables. I was skeptical about buying from a company I'd never heard of before and was particularly concerned about the connectors. These connectors are of the highest quality: on par with or even better than Amphenol or even Neutrik connectors! I wouldn't hesitate to drag them over tile, linoleum, or even smooth concrete. The outer insulation is rubber, which I like. I'm not sure I even need to train these cables as usual. Even when rotated or hung on a pole, they return to their original shape. I will definitely be returning to GLS Audio for more.
