I never take seriously all those "dog's talks" about audio quality, compression, digital vs. analog and so on, after I read an article in authoritative Russian "Stereo" magazine with a review and comparison of 5 optical TOS-link cables. They used so many words to describe characteristics of sound of each cable: one was warmer, another was metallic... you know the stuff. I understand that there are people, who can notice the difference, but they are not the people who talk about it.
