Burn-In *

We can burn-in your cable for up to 96 hours FREE of charge using our Nordost VIDAR cable burner. This is a £3000 machine that will optimise the performance of your cables from day one. This means the cables will be in optimum performance mode when you receive them, so you'll be able to make a performance assessment quickly rather than waiting 70 hours+ of usage. The result of conditioning cables with the Nordost VIDAR is, improved sound staging, increased detail, and an overall more musical presentation. Please Note: we are unable to burn-in cables with stripped bare ends, BFA-only plugs, or no plugs selected. (This does not apply to BFA/Banana plugs). Cables are burnt-in for the selected period AFTER your order has been processed. This service is offered at Future Shop's discretion and we cannot guarantee all burn-in requests are fully completed during busy periods.

Tellurium Q Black II RCA Interconnect

 

What Tellurium Q say

The new Tellurium Q Black II interconnects are now available! Like the old design but with better detail and more "real" sounding and, best of all, exactly the same price as the old design!

PLEASE NOTE: lengths longer than 1m usually ship within 7-10 days

Please note that these interconnects are directional and for the best sound the signal must travel in the direction of the arrow near the centre of the cable.

The grip in the phono plugs is adjustable enabling you to get the best possible fit.

 

To minimize vibration and noise, each RCA connector is sealed with an anti micro-phony compound to damp excess vibration in that part of the signal path. This helps to enhance the silent background in your system.

Contact Enhancer Option

To ensure the best possible connection between your system, Future Shop recommends the DeoxIT Gold G-Series contact enhancer.

DeoxIT Gold is carefully applied to the plug contacts of your cable and is a unique conditioning solution designed to improve conductivity and provide long-lasting protection on gold, base metals and other precious metal contacts and connections. DeoxIT Gold penetrates plated surfaces, molecularly bonding to the base metals to seal and protect both surfaces.

The benefits of applying DeoxIT gold are:

  • Improved Conductivity
  • Maintained optimum signal quality
  • Reduced wear & abrasion
  • Prevents fretting/dendrite corrosion
  • Forms a protective anti-tarnishing coating
  • Stabilises connections between similar and dissimilar metals
  • Reduces arcing, RFI and intermittent connections

Please select this option from the above ‘Contact Enhancer’ drop-down menu and our engineers will apply the contact solution to your cable connectors prior to shipping.

“Putting it into my system, I was impressed by just how communicative this modestly priced cable was. Compared to my favourite similarly-priced cable I had to hand TQ offered a significant improvement in focus, timing and overall lucidity.”

Steve Dickenson - HiFi+

"Nowhere does the music sound sharp or thin, but very open, transparent, defined. Everything sounds completely balanced. The sound is completely separate from the speakers and we feel as if we ourselves were present at the shooting. The original setting is left untouched and had only experienced by some in this group test such a commitment. So pure, so much momentum and so much peace. This is for us very close to the perfect interlink."

Harro Tillema - Alpha-Audio

 "Black RCA curious change occurred. First, there was a sense that the overall picture is somehow simpler, it slightly diminished shades and tones. In fact, to get the effect "grated window" - the spectrum of nuances become more apparent and clearly. He became more visible contribution to the tweeter, while the explicit emphasis on RF failed.The music became more interesting to listen to."

Nikolay Efremov - Audio Video

 “I’d say it sounds one of the very best cables at the price”

David Price - HiFi World 2011

"Working at all frequencies and all types of music excellently it opened up the music in a way that many other companies can only dream of, that focus on phase relationships doing its thing. This worked so well with different systems and I would heartily recommend having a listen, however expensive your system is."

Equipment Review - HiFi Pig - June 2nd 2021

"I have no idea what Tellurium Q Black II is doing, what it’s doing that original Black wasn’t doing, and why. But when Black II is doing what the cables are supposed to do – play music – those empty musings just fade away. It doesn’t matter why Black II works, what’s important is that it does work. I can see the cable being used in a range of outstanding value systems, making them sound at once smooth and inviting and also rhythmic and musically engaging. It’s a cable to enjoy music by!"

About Tellurium Q Made in United Kingdom

Tellurium Q cables offer a unique approach to cable performance, focusing on minimising phase distortion, a common problem inherent in all cables. The Tellurium Q team understands that all signal path materials act as electronic filters, impacting the naturalness of vocals and overall audio quality.

Instead of ignoring this issue, Tellurium Q embraces it and engineers cables that provide a clear path for the signal, aiming for the most natural sound possible with current technology. Their construction involves multiple stranded conductors of varying materials, dielectric materials, and geometries. Every detail, from solder mixes to plating thicknesses, is carefully considered.

Tellurium Q has developed three distinct families of sound to cater to different customer preferences: the Tellurium Q Silver range offers silver-like characteristics without harshness, the Tellurium Q Black range (including the Tellurium Q Black Diamond) provides transparent and lifelike reproduction, and the Tellurium Q Blue range adds a slight warmth to balance brighter systems. Each range is designed to enhance the audio experience uniquely. They strive to offer a clear, transparent, and natural listening experience and invite customers to hear the exceptional results of their work for themselves.

Having entered the Hi-Fi scene in 2010, Tellurium Q has won several coveted awards and global recognition. With their extensive range of top-tier cables available in 37 countries, they've accumulated 154 exceptional reviews and 14 'Products of the Year' awards from international Hi-Fi magazines. They have twice received the 'Queen's Award for Enterprise' in recognition of their remarkable export growth. Tellurium Q's uncompromising commitment to excellence ensures its products are not just good or average but exceptional, offering customers the best available in its price range.

Customers consistently praise these Tellurium Q Black II RCA interconnects for superior sound quality, citing improvements in clarity, soundstaging, bass control, and detail across various audio systems. Build quality is noted as excellent, with securely fitting screw-on connectors. Multiple reviewers report upgrading from established competitors and finding these cables deliver comparable or better performance at a competitive price point. Service from the retailer (Futureshop) receives consistent praise. One reviewer noted the original Black model required replacement while the Black II proved more durable, and another suggested the Black II may offer better value than higher-tier alternatives. No significant negative themes were identified beyond one comment on overall pricing concerns.

A good cable but getting too expensive 9 July 2026
Originally had Black RCA and Ultra Black II RCA, and the Black went back quickly. Ultra Black II was so much better: clearer sound, better sound staging, more air and deeper, tighter bass.

I used them for several years before moving them on. I would buy them again, but the Black IIs would be where my money would go, especially if the improvement is in line with the Black II’s speaker cables

All Telliurium Q Cables sound fantastic to me. 24 June 2025
The Tellurium Q Silver speaker cables are outstanding. The TQ Black II RCA interconnects are also outstanding in my opinion.

I wish I had the money to upgrade to the next level!

Superb 4 May 2025
With these cables, you can have a home cinema dream. Connect the whole system with these: a preamp, subs,a DVD player, and power amps.

The sound is utterly captivating, 10/10.

You won't find a better interconnect, at any price.

Great cable 24 April 2025
Great cable, taking advantage of the updated Digital-to-Analog Converter in my Cyrus 40st running through my Cyrus i9XR integrated amplifier.

Big thanks to Hezron at Futureshop, very helpful.

A Superb Upgrade 19 July 2024
This Black II Interconnect replaced a more expensive one from a very reputable British cable manufacturer. I had no complaints with the original interconnect; it was more of an experiment, as I bought some Black II speaker cable for a second set of speakers and loved the result. I will now slowly replace all of my other cables with Tellurium Q Black. The two I already have brought a welcome dose of refinement to the system without losing any detail or musicality.

The Black II range may be a little lowly in price point, as my system is pretty high-end. I only started with the humble Black as an experiment, but I see no point in spending any more at this point as they are (to my ears) perfect!

Well made great sound plugs fit well. 27 March 2024
Great service from Future Shop. Mark was great, as usual.

The cable, Tellurium Black II RCA interconnect, is beautifully made, like the way the plugs fit by screwing on the components. It runs from my DAC to my headphone amp, and the result is great.

Fantastic cable that broughty CD player back to life 7 December 2023
Stunning cable. I only just bought it for my Michelle Girodec record player, which made a huge sound improvement.

Trying it on my CD player was so good so that I ordered another set. I'm really happy, as the player (Marantz CD17) lacked clarity and sounded dull.

What an improvement, I can't recommend it highly enough. Fantastic value for money.

Very good cable.. 21 April 2022
Excellent cable. I have had them all from Cardas to Black Rhodium, and the online reviews are correct with the five ***** reviews of the Black ll.

I can’t ask for anything more. I would also like to say I have tried the ultra also, and the difference is nothing in it, really.
Stanislaw Bugajski ✓ Verified Purchase
excellent cable 20 March 2022
Hello, I have used the QED Signature Audio 40 RCA interconnect so far, and they are great, but when I plugged in the Tellurium Q Black II Audio RCA, I had even more resolution and more bass.

I highly recommend these cables, although they are not cheap, I think they are worth spending more money on.

Thank you, Futureshop

What a difference! 7 October 2021
Well, I've always been aware of the differences cables make to a system. I bought a pair of these after fitting the Tellurium Q Black speaker cable in my system, so that tells you something about how impressed I was with them, to invest in a pair of these interconnects. The interconnects sit between my phono stage and integrated amp, replacing the VDH interconnects I had.

The difference was immediately obvious, the first thing to hit me was the depth and control of the bass. It's lower, faster and controlled as I've never heard in my home system before. The soundstage imaging and separation have all improved considerably. What really strikes me is how natural and smooth my system sounds with these cables in place. I didn't think I needed to change anything in my set-up, but after reading reviews and speaking to a friend who has these cables in his system, curiosity got the better of me, and I'm glad it did!

In truth, I'm only 1 album in, but the improvement and just in general, how good my system sounds now (even though it did before) prompted me to write this review. The biggest and most obvious difference and improvement I can ever recall after simply changing interconnects.
Incredibly good cables, highly recommended! Outstanding service from Futureshop, as always!

Amazing RCA’s 10 June 2021
Absolutely brilliant product. If you want to know how it sounds, go to the speaker Black II cable’s reviews as it the same sound.

Makes the high frequency less harsh, voices and mids very clear and clean, plenty of details , great dynamic.

The bass is very well controlled and not boomy. A very big improvement over very good QED signature audio 40 RCA cables.
Highly recommend.

Now I only need Tellurium Q Black II USB to have the full set of TQ black II cables.

Can’t wait when the USB cable will be available in Futurestore.

Futureshop customer service also really good and highly recommended. Very happy client.

Enhance Your Experience: Free Cable Burn-In Service with Nordost VIDAR Machine

 

Please take note of the following details regarding our cable burn-in service:

  • Cable Compatibility: We regret to inform you that we cannot burn-in cables with stripped bare ends or BFA plugs. In order for cables to undergo the burn-in process, they should be terminated or have connectors.
  • Timing: Cables will be burnt in for the selected period after processing your order. For custom-length cables, the burn-in process will occur after they have been terminated by the manufacturer or our engineers unless specified otherwise in the product description.
  • Availability: Future Shop provides our cable burn-in service free of charge, but its availability is at our discretion. While we strive to fulfil all burn-in requests for the specified time periods, please understand that during exceptionally busy periods, we may be unable to meet the demand due to limited connections on the Nordost Vidar cable conditioning machines.

The Nordost VIDAR cable burn-in machine integrates three key functions into one operation:

  1. Charge Neutralisation: It eliminates charges that accumulate around the cables and their insulation, ensuring a more balanced electrical environment.
  2. Deep Conditioning: The machine provides a wide band and deep conditioning process that affects the conductor core, resulting in changes to the signal transmission through the metal. This deep conditioning enhances the cable's performance.
  3. Ultrasonic Surface Conditioning: The VIDAR machine utilizes ultrasonic waves to condition the surface of the conductors, optimizing their contact and overall conductivity.

The VIDAR employs a proprietary combination of composite and complex signals to condition the cables. These signals comprise ultra-low and ultra-high frequencies, extending beyond the range of video frequencies. The signal moves back and forth along the cable, penetrating deep into the core with ultra-low frequencies and traversing the surface with ultra-high frequencies. This transmission method generates beat harmonics between the two complex waveforms, which permeate all layers of the cable. The circuitry of the VIDAR also drives electrons from the conductor into the insulation area, neutralizing electrical charges.

 

 

Nordost Vidar Burn-in Machine

 

 

So, what does this all mean for you?

The ultimate outcome of conditioning cables with the Nordost VIDAR is improved sound staging, increased detail, and an overall more musical presentation in your audio system.

Now, you may wonder why cable burn-in is necessary. During cable manufacturing, gasses become trapped as insulation is applied over the conductors. Additionally, new cables often possess high electrical charges, resulting in a brittle and bright sound that lacks the desired detail and depth for music production.

When cables undergo burn-in, the trapped gasses are dissipated, and small impurities in the conductor metals begin to exhibit diode-like behaviour, favouring current flow in a specific direction.

Here are the physical effects of the burn-in process:

  • Charge Neutralisation: The burn-in process neutralizes charges in the conductors and insulation, promoting a more balanced electrical environment.
  • Wide Bandwidth Frequencies: The conditioning affects how signals pass through the metal, enabling a wider range of frequencies to penetrate all cable layers.
  • Signal Transmission: The burn-in process establishes the directionality of the cable, optimizing signal transmission from one end to the other.

When cables are properly burnt in, you can expect the following audible changes in your audio system:

  • Fuller and Natural Sound: Your system should be capable of producing a more immersive and realistic performance with a fuller and more natural sound.
  • Increased Detail: You may notice enhanced details and nuances in the music, allowing you to perceive subtle elements that were previously hidden.
  • Improved Soundstage: The dimensionality of your system's soundstage can be greatly improved, creating a more spacious and immersive listening experience.

At Future Shop, our goal is to maximise your satisfaction. That's why we offer a free burn-in service on all our cables before they arrive at your door, enabling you to sit back and enjoy the benefits of properly conditioned cables in your audio system.
