I had until then my Mac Book a "0815" - connected jack Chinchkabel with my stereo system. Trigger to get me a new a new cable, were now and then contact problems, so every now and then a channel failure. After the good review of Oelb. cable I decided for this. I have not looked back. A significantly better sound. A better channel separation. That there are such differences between connecting cables, I did not think.
