DIN TO PHONO RCA
The Statement Din to Phono RCA cable links your turntable to
the rest of Tellurium Q Statement cables giving you more and that one little
word “more” describes it better than pages of superlatives.
We hope you enjoy your vinyl….more
Foreword by Geoff
Tellurium Q® is often asked what do we do
that makes our cables perform so well? The simple and unsatisfying answer is
that we do a lot of little things together that mount up to be very important
in preserving the relative phase of a signal. People assume that to get the
best performance the “fastest” conductor – pure silver of something even better
has to be used. Which is also one of the reasons for the pointless chasing of
nines as I call it i.e. copper to 99.9999999% purity as if that is the single
most important factor for a cable!
Surprisingly, to get the most natural sound, it is not just
about merely conduction. This is the reason, any conductor from any cable
manufacturer on this planet will act as an electronic filter and by that I mean
that the various frequencies relative to one another get shifted with each
material they pass through and are also affected by insulators, geometries,
shielding etc.. The interesting thing is that materials affect ranges of
frequencies in dissimilar amounts. It really is a finely tuned balancing act to
make sure that you get a natural, transparent transmission. This takes a LOT
more research than people would imagine. Even down to the solder that we use.
Not standard by any means for the audio industry and we have tried numerous mixes
and diverse percentages of silver in the solder but at the end of our testing
and development we find we have a solder with no silver whatsoever (no lead
Even the process by which we solder and the
temperature/time, “envelope” to complete the process is tightly controlled and
specified and it is not the same for each cable either!
The connectors may look relatively ordinary but have
multiple layers of plating and not always the material you would expect. There
is even more detail and precision within the plating process itself, because we
specify the thickness of the plating and what has to be in the plating bath and
what should not be.
These are just a couple of tiny details that make up just
one small part of one cable. The detail, precision and care is the same for the
rest of the products. And each little step needs a controlled listening and
testing against other options which is immensely time consuming but hopefully
the results speak for themselves.
From what we have learnt, especially in the last few years,
we have been able to bring you the Statement cables. They are the
Tellurium Q® Statement of the performance that we think is

When Tellurium Q® was set up the focus was
primarily on phase distortion and minimising this problem inherent in all
cabling, whoever makes them and where ever and however they are made. The
reason it is a problem is simple, all materials (not just cables) in the path
of a signal will act as an electronic filter according to the definition in the
box below, whether you want it to or not. This is undeniable.
Please understand we use the word filter as its scientific
definition and not necessarily as something being “filtered out” like with a
mechanical sieve. We are primarily focused on removing the smearing of
frequencies through a timing shift, and by doing this you get better clarity
and transparency from Tellurium Q® cables.
“A filter is an electrical network that alters the amplitude
and/or phase characteristics of a signal with respect to frequency. Ideally, a
filter will not add new frequencies to the input signal, nor will it change the
component frequencies of that signal, but it will change the relative
amplitudes of the various frequency components and/or their phase

N.B. This is true of all speakers, amplifiers, DACs, CD
players, cables etc…in fact anything in the signal path.
Once you accept the fact that your audio system is acting as
multiple electronic filters smudging your music, then you have a choice:
a. Forget the cable is an electronic filter (completely in
the face of science) and compromise by having a smeared sound or
b. Do something about it and engineer as clear and phase
neutral a path for the signal as possible to get the most transparent sound
that current technology will allow, and preserve the original signal phase
relations as much as possible.
Unfortunately, it is not as easy as just looking at a chart
of materials and simply picking the one with the best conductivity. If that
were the case, then you would put some silver wire in place and the job would
Some time ago, we had some pure silver connectors
manufactured and like all our developments, tested them in a double blind
situation. These we put against silver plated connectors using various base
metal mixes and various thicknesses of plating. The pure silver performed worse
than a plated connector with a “certain” thickness of plating. It was sluggish
and almost muffled by comparison.
The more you focus on the fact that you are working with an
electronic filter, then the easier it becomes to craft a much more transparent
and natural sounding cable, engineering each part of the signal path to
minimise distortion. But there is a huge downside to this, as every little
detail of the constituents used and construction has to be tested in multiple
configurations….and of course listened to.
The cable construction becomes more complex, using multiple
stranded conductors of slightly differing materials and various dielectric
materials and geometries. We have to pay attention to every part of each of our
processes. Even using non-industry standard solder mixes varied between cables.
Raw ingredients for the construction are highly specified, as are plating
thicknesses, even down to specifying what chemicals should or should not be
included in a plating bath.
Relative conductivities of various metals
assuming copper to be 100%
The shiny finish is less conductive because of the additives
used for that finish when plated. However, that is not a great issue when you
take into account the material underneath, cable construction and any other
plated layers – we still end up with a very transparent cable assembly. It is
all a very carefully balanced set of ingredients that become more than the sum
of their parts.
We have taken a different and radical approach by looking at
the “problem” of cables because they are “secret” electronic filters and you
ignore that at your listening peril.
By thinking of cables in this way we can get
closer to the goal of preserving the relative phase relationship in a signal
meaning that you hear the most transparent, natural sound possible.
