The Silver Diamond Waveform™ hf USB boasts the silver family of sound quality and, as you would expect, is a step forward from the performance of the Black and Ultra Silver USB.

“I was immediately struck by how much the Tellurium Q [Silver Diamond ] seemed to lower the noise floor. Notes emerged from a much quieter background – the Clocks at the Pink Floyd’s “Time” were startlingly striking. If you want to hear the full musical range of your digital files then it is a must.”

“The first serious meeting with Tellurium Q products turned out to be unexpectedly interesting. An English company is considered a phenomenon, its products are said to be doing well against any competition, and several industry colleagues use them in their work.

I talked to Geoff several times and he gave the impression of a man who is 100% sure what his products are doing. More than once, he announced it to everyone and to him in a completely unforced way, as if it were an obvious truth. Now I know why. He just knows it from the inside and is not surprised.

Tellurium Q Silver Diamond hf is on many planes clearly better, capable of alterations that are beyond the reach of the product of the native operation”
