The Black Diamond XLR uses Tellurium's own TeCu connector and is the most natural sounding cable in the range, which is saying something. These XLR interconnects have been designed to have the lowest capacitance that Tellurium could build in and the highest possible bandwidth with enhanced shielding.

PLEASE NOTE: 1m usually ships next day.

Tellurium Q's listening tests of this Ultra Black II RCA against the old version gives a wider soundstage more accurate and even "quieter" in the gaps between notes. Of course a significant and easily audible improvement as you expect from Tellurium Q. The first of the RCAs in Tellurium's range to use their new TeCu connector.

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.

Ultra Blue II looks pretty much exactly the same as the old Ultra Blue except for the “II” denoting the new generation cable. Plug in a burnt in Ultra Blue II after the old version and you will hear within seconds why we have upgraded this cable. The sound is fuller, more organic and better balanced in the whole range. The top end detail is still the same but everything else has risen to that performance level.

Even taking in account all the awards that the old Ultra Black speaker cable won, this new version gives a whole new level of performance that is obvious from the first second of listening. Greater detail, more clarity, more organic but still sitting very firmly in the Black cable family.

While the “Black range” (Black, Ultra Black and Black Diamond) could be categorised as neutral/ natural the “Silver” would lean more to neutral, detail and extension.

Tellurium Q Speaker Cables are also available in Bi-Wire configurations, Please contact us for more information.

A rare true-neutral cable, the Black II is a multi-award-winning upgrade on the already remarkable Black which announced Tellurium Q as an industry leader. This is an excellent cable across the spectrum of sound, providing top-notch clarity in perfect balance with full, deep bass and a wide-open sound stage. Jumper cables are a useful alternative to bi-wire cables that also ensure optimal signal transfer between your speaker's high and low binding posts. For best results, match these with the Tellurium Q Black II Cable.

Keeping the same family sound as the Black but taking it beyond the Ultra Silver on the way to the Silver Diamond. The Black Diamond is the newest in the Waveform line up but sits very firmly in its performance slot of the Tellurium Q matrix.
