TELLURIUM Q

Tellurium Q® : Our Focus

Tellurium Q® have been asked many times why our cables perform differently to others. We are not going to pass on the exact details of what we are doing to achieve the performance that the reviews and multiple product of the year awards talk about, however time moves on and so it is time to talk a little more about the how.

 

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 focussed on removing the smearing of frequencies through a timing shift and by doing this you get better clarity and transparency from Tellurium Q® cables.

This is the definition of an electronic filter:

“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 relationships.”

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 be done.

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 that 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.

Let us give you an example of what we are talking about. These two plated finishes (both silver plating) conduct differently to one another.

 

 

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.

Although cables should not affect the sound there are factors that have to be considered because audio systems are not perfect and customers have listening preferences too. So you will see we have engineered three distinct families of sound to take account of three distinct demands our customers have asked for. Which is why we have the Silver and Blue ranges as well as the Black which help achieve this for our customers:

Silver range: The sound can best be described as silver but without the fatigue and harshness that can go along with that material.

Black range: the natural / transparent range that allows an incredibly life like reproduction for use in a well balance system to simply unlock what the system can do.

Blue range: slight warmth that just takes the harsh top edge out of a system that is a little brittle or bright. 

So now you know why our cables have won so many awards and we have grown so quickly. 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 our goal of combating phase distortion (or more accurately, preserving relative phase relationships in a signal) giving you the most transparent, natural sound possible.You can think of it like a blurred picture becoming clear

We would like you to have the most clear, transparent and natural listening experience and so hope that you get the opportunity to hear the results of our work for yourself.

Tellurium Q® Partners With Authentic Vision

 Made in Britain products secured by Austrian security labels ready for counterfeiting challenges around the Globe

 

World-wide premium reputation & hand built in Britain  – these are just two of many reasons why Tellurium Q® wants their clients to have confidence that they own authentic, high performance cables. Tellurium Q® and Authentic Vision have joined forces to enable customers to securely check the authenticity of their cables just by scanning the warranty card with the Check If Real App – free to download at the App Store for iOs or Google Play store for Android.

“We have chosen Authentic Vision because of the concept they are bringing to the market. Such a simple yet effective use of technology to benefit our customers. There is always a danger of any manufacturer’s product being counterfeited, that is just a fact of life in this day and age. So we have decided to act proactively and safeguard our customers before it ever becomes an issue and with Authentic Vision on our side it never has to."
 



This is why Tellurium Q® have partnered with Authentic Vision:
 An online system driven from encrypted physical labels that  allows our customers to instantly check product authenticity for themselves just by scanning the product with the Check If Real app on their smartphone.
“It is a bit of a game changer”, comments Geoff Merrigan, Director at
Tellurium Q®
 
“We are particularly happy that Authentic Vision was able to work with Tellurium Q® and ensure all the customers about the origins of their purchase without any lengthy processes or examinations – one scan is enough – which is the easiest to use authentication solution for customers worldwide.” Says Peter Kostur, VP of business development at Authentic Vision.

How it works:

  • One: Tellurium Q®’s warranty cards has an Authentic Vision label - a highly secure, irreproducible configuration combining randomised 3D holographic image with an encrypted datamatrix.
  • Two: The Check if Real smartphone app instantly authenticates your product as genuine.
  • Three: Direct and automatic access to product registration and extended warranty the instant that you authenticate the product using Authentic Vision.
 
 




Background:
Authentic Vision is essentially a new system developed to authenticate and protect products from grey imports and give customers confidence that they have the genuine article.  Tellurium Q was approached by Authentic Vision to pioneer and partner this game changing technology because of the reputation of their products.

This is being rolled out into the UK later this September and the rest of the world in October.
