The Black Diamond level is Tellurium Q on a cable. These cables have just been released and are the work we are most proud of. The Black Diamond uses our own TeCu connector and is the most natural sounding cable in its range, which is saying something.
Mono & Stereo Review:
“If there is such a thing as a completely neutral interconnect, then the Tellurium Q Black Diamond probably fits this description like no other cable.”
