It has been a while since I had a brush with Tellurium Q products, however, I regularly receive questions from audiophiles who ask which of their cables will be the most suitable with this or another system. I even get the impression that some music lovers try to solve this puzzle in the worst possible way - not based on the listening but rather the reviews, users' comments, and comparing weird figures found online. Yet, they are still convinced that they should buy Tellurium Q cables. They just wonder whether they should choose Blue, Black, Black Diamond, or Ultra Silver series, even though there are lots of other very interesting cables on the market. Why these, then?
