The biggest problem in audio is that there are a lot more average cables than exeptional good cables. Personally I hate these products. Why? Because at the end they will give many people a lower end result of there set. Every different brand have there own qualities/properties. When you are not aware of those, you do not understand what it will bring into your set. Differences in how the image will be is huge. Same about resolution, speed, depth and even decay. When people send me a list of what they use, often I see the mistake peope make. Because of the thousend of tests I did in 16 years of time I know how the overwhole image will become. When you are not aware of the properties of your amp, source and cables. You do not know what kind of properties/qualities you need.
