““Dynamic but delicate”was my description, with very expressive “Tellurium mid”, with a great ability to enable music to “move”; overall very clean presentation and articulate across the band. Noted good low frequency shape, and power.”

Comment from a highly regarded speaker manufacturer.

Tellurium 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.

“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.”

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

We recommend low mass beryllium copper z plugs but there is also the option of low mass spade termination for systems that require it.
