Tellurium Q Silver Diamond XLR Cable (Pair)
Tellurium Q Ultra Silver XLR Cable (Pair)
Tellurium Q Ultra Black II XLR Cable (Pair)
These are a significant step up from the old Ultra Black XLRs (as you would expect from any of tellurium Q's developments by now). What they found in their listening tests is that the Ultra Black II's are smoother, more accurate and more detailed with more depth / 3 dimensionality. Built to complement the astounding Ultra Black II speaker cable but also stands alone with its performance profile.
