Just like all our cables the digital RCA cables are hand built in Britain for performance. Some think that the idea that improving the signal path for digital signals is a waste of time. However a digital signal is not a 1 or 0 as is often thought but an analogue pulse and so the same care and consideration has to be taken with the construction of a digital cable as with a pure analogue cable. The 1 or 0 is result of the signal being “read” and that is the binary piece of information not the electronic signal in the wire. That is the way we think of it and why we build the cables the way that we do.

Here is a simple and non-technical way to view a digital signal in a wire and while not what happens it is a more accurate model than a one or zero. A single electron is not enough to trigger a response from audio equipment. So we need to think about the signal as a “swarm” of electrons almost with a shape. To turn a signal on or off requires a small amount of time and a magnitude of the “swarm” is necessary, the shape of which is affected by many factors and which in turn affects leading and trailing edges as they are read. However as we said, while a little closer to the truth this is still not what actually happens.

Our Waveform series has been refined and radically reworked to give an even purer signal path than before with the development of Waveform II.

Where does this cable's performance belong in the Tellurium Q families of sound?

what else could Silver Diamond possibly bring? ̈Is there actually to improve upon the already phenomenal Ultra Silver Waveform™ II performance?

Upon inserting the Silver Diamond RCA digital cable the answer became immediately obvious: a resounding yes. Just when I thought the limits were reached - the Silver Diamond went further!In particular the extension at the extremes was even better and the openness of the midrange spectrum helped to cast an even more believable sonic picture. The vocals were sensationally immediate and alive sounding; the human touch was highly authentic. The bass spectrum gained in punch and control and the instruments had even more body and thus seemed even more realistic - despite being already exemplary with the Ultra Silver RCA cable. The uppermost octaves seemed even more open and limitless in their extension with the Silver Diamond and this in turn gave even more airy presentation of various recording venues.

“SD is a generation ahead in terms of its capabilities, principally because of the vast amount of noise it removes from the soundstage and the clarity that it brings as a consequence.

The Tellurium Q Silver Diamond RCA is one of the all time great digital cables that, if you can afford, you really must own. Once you’ve heard this design provide its amazing sense of realism, then any other digital connection tends to pale into insignificance. Brilliantly transparent, the Silver Diamond is likely to dominate the digital cable hill for many years to come.

"Silver Diamond is extraordinarily transparent, satisfyingly open, full-bodied, with an awesome bass, and extremely sweet and smooth across the midrange."

The new Ultra Silver Waveform II design is a big departure from the original version and judging by the response it is getting, it is a significant development, this is a direct replacement and upgrade of the Graphite waveform:

The thing about this cable is that, after 10 seconds of listening, there is so much good stuff to write about that you feel like typing four paragraphs worth of superlatives which destroys the listening flow, I can tell you.

The removal of a host of distortive noise gives music both space and time to flow forth. The increased silence and air that the TQ allowed into the music gives the sonics time to add both character and structure to each note. What you are faced with then is unparalleled character and focus that demands your attention."

“The first cable on the “test bench” was the Tellurium Q Ultra Silver WaveformTM II (RCA) digital cable. After inserting it into the system, I couldn`t resist to smile and my grin was ear-to-ear. There are times when we audiophiles and music lovers think there is hardly anything that could surprise us, well...the Ultra Silver RCA digital cable proved to be a darn big surprise.

"The first impression of the Ultra Silver WaveformTM II digital cable was: incredibly organic, transparent and refined! The amount of musical information this cable dug out seemed nigh impossible at first but after the initial shock I simply began to enjoy its utterly natural sonic delivery. In a sense it was very difficult to dissect the sound into numberless audiophile criteria because the sound was so holistically homogeneous, natural and self evident that trying to pin down the various aspects of reproduction quality seemed quite, err...in a sense, pointless. This cable`s main strength is actually in its ability to seduce the listener into absorbing the musical message - and leave the cheap audiophile pondering aside.”

"Tellurium Q Ultra Silver, which is the company's newest cable, playing with a mega large sound stage and lots of nice details. And an incredible precision and delightful musicality. ...without being analytical, or sharp to hear. Just lots of detail on the palette..... a differentiated transparency and an incredible transient reproduction and brawn in the bass .... musical and precise sound"

“Best digital cable we have ever tried, I believe it is really special”

Now discontinued in favour of the higher performing Ultra Silver version.

The reference level graphite takes what the black range does so well and then goes beyond that performance.

The circuit board in each connector that was designed to actively prevent jitter is also embedded in an anti micro-phony compound to minimize vibration.

“It’s actually irrelevant which Tellurium Q cable you select to compare against its Nordost opponent, it’s more that the difference in the nature of the performance of both ‘families’ is so huge as to render the ‘bits is bits’ idea laughable to any listener. Curiously, I had expected this difference to be less significant, because both Nordost and Tellurium Q have a reputation for leading the field in leading-edge resolution. This turned out to be correct.”

“I would like to share with you my impressions about the Tellurium Graphite Digital RCA. I expected the typical not breaking in cable sound: harsh and analytic. But it was worse!! In addition to this, the cable didn't had highs nor lows… It sounded like a rigid wire.

At this point I doubt seriously if it would be a good cable!!!

A little latter is when I discovered the Tellurium Q System Enhancement CD… it’s a CD about 70 minutes of playing time that comes in 3 cuts…. And at the end I saw the light!

It’s a break-in and system enhancement CD that plays a signal that signal that cover the whole hearing spectrum.

Oh my God!!! How good this cable sounds!!!

It has moved from earth to heaven… it delivers all the sound that your CD transport can offer… it’s quick, it’s firm, clean and has brutal dynamics!!!

It respect the highest and lowest frequencies… but it doesn’t widen nor reduce them… with a Divine entirety in the bass and a prodigious musicality in the highs.

Paco… you were right. I am very proud of this cable!!! And even more bearing in mind that it costs less than 1000€… everything it delivers and in the way it does it, it’s a very cheap cable!!!!”

The Black Waveform II digital RCA builds on the success of the original Black Waveform but in a completely different way to give a clean, natural sound.

The entry level Blue Waveform II takes over from the original waveform with the same architectural approach to improving digital signals as the other Waveform II digital RCA cables. When you hear the difference you will agree that there might be more going on than a 1 or 0 because hearing is believing.
