“Tellurium Q Ultra Black is the cable we wanted to make from day one. We told our UK distributor what to expect as we handed them a prototype that looked more like a fireman’s hose and less like a sonic phenomena. They glanced at the heavy, stiff and it has to be said ugly brown experiment. “Yes, well we will give it a go and take it to a few dealers to see what they think”. Later that day we get a phone call from our disbelieving UK distributors at Kog Audio, “what the hell is in it? We’ve never heard anything like this!”.

They took it on trust that the production version would be incredibly thin and flexible by comparison and look a whole lot better. So Kog Audio put in an advance order that day without needing to see or hear the production model because, in their words, “if it is even quarter as good as the prototype it will blow people away”.

We think that the production version sounds better than the prototype.

At first glance you could be forgiven for thinking that the Blue Diamond and Ultra Black were the same cable with different printing but when you plug the Ultra Black into your system there is absolutely no doubt that the Ultra Black is in a totally different league.”

The Tellurium Q Ultra Black cables achieve component status: that is to say, before changing any of your system’s components you should audition these cables first”

“The extension is incredibly clean and natural and I must say that I didn’t manage to find that in another cable until now… I’ve been listening to some live recordings which were incredibly real, from the sounds in the audiences, to the voices and instruments on the stage. Even the clapping was hauntingly lifelike, putting me right there in front of the audience.”

“naturalness , timbres and dynamics of these connectors are so remarkable that my packing and sending back is really very, very difficult – if it even still happens.”

“Whatever you do, don’t audition the Ultra Black. As I said before, once you do, there’s no going back.”

“What the Ultra Blacks will do for your record collection is to both extract the fine detail from within and reveal its personality. The Ultra Blacks will lay bare your music, getting under the skin of each recording.”

“clarity is the only word I can really find to describe the effect of these cables, and I must admit (as a cable sceptic full stop) it shocked me”.”

“So what is it that the Tellurium Q’s do and the other cables not? Or do but only to a lesser extent? They are damn musical, for one thing. Second, they appear to diminish harshness of the digital sources. Third, they let the midrange shine. Fourth, they keep the low bass frequencies well under control. Not bad for a pair of cables.”

– Kai Ekholm,inner-magazines.com

Cable sceptics

“… things seem to start and stop when they ought to and this adds to what I can only describe as a sharper aural image. Clarity is the only word I can really find to describe the effect of these cables”
