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 Waveform II HF Digital RCA Cable

 

The Black cables by Tellurium Q were a multi-award-winning range, but Tellurium decided that to overhaul the whole series. The result is the Black II range, an upgrade on those already exceptional cables, Telbut delivered at the same price as the previous generation! This product is the new version of the Black Digital RCA cable, and features high-quality plug terminations for an optimal connection which maximises signal transfer. 

 

What Tellurium Q say

 

Developed from and improved upon the previous acclaimed waveform cables, this build can be specified as BNC or RCA at one or both ends. The new hf class of waveform cables have improved shielding and has in its tech arsenal some other interesting developments that help the digital signal.

The Tellurium Q Digital RCA has been designed differently from what you would expect. Many people think that a digital cable is just a digital cable but you may be surprised that this one really does make a difference in your system.

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.

 

Tellurium Q Black Performance Graph

 

“With the Tellurium Q cables the notes and sounds become music, contexts become clear, emotions transcend musical reproduction, you can hear the wood, the vibration of vocal cords: magical. …the digital cable offer great bang for your buck”

Christian Bayer - Image HiFi.com

“This turned out to be an interesting and almost immediate over tuning of any ‘bits is bits’ mentality I might have still been harbouring.”

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.

 

 

About Tellurium Q Cables

Somerset cable maker focused on phase distortion, with Silver, Black and Blue families tuned to different system balances.

Tellurium Q builds its cables in Somerset around one problem: phase distortion. Its designers start from the view that every material in the signal path acts as a filter, and they combine multiple stranded conductors, different dielectric materials and different geometries to reduce the effect. Even solder mixes and plating thicknesses are chosen with the same aim.

Three families, three balances

The Silver range is designed to give silver-like character without harshness. The Black range, which includes Black Diamond, aims for a transparent and lifelike presentation. The Blue range adds a little warmth to balance a bright system. You can pick the family that matches your system before choosing a level.

Several levels within each family

Each family has three levels: the standard models (Silver III, Black II and Blue II), the Ultra II models and the Diamond models, with a Statement line alongside them. You can choose a family for its balance first, then decide which level suits your system and budget.

Every connection from one designer

Tellurium Q makes speaker cables, interconnects, power cables and jumpers or links across its families. Because all of them come from one design approach, you can carry the same thinking from source to speaker, using a family chosen for its balance for every cable in the chain.

Why we stock Tellurium Q

Tellurium Q are the brand customers tell us about unprompted. Black is the range that sells and the one people return to buy more of, usually after hearing what a single interconnect did. Fourteen years of selling them and the feedback has not shifted, which is rarer than it sounds.

Part of suite of upgrades and worth it 19 April 2026
Final part of my upgrades to a good system. Allows the CD transport to get everything on the CD to the pre-amp without messing with it.

Very happy. Soundstage is good. Not too bright, and the detail is excellent. Bass is tight and not overpowering. Even my wife noticed a difference.
tony ✓ Verified Purchase
outstanding 5 May 2025
Due to cost, I was using a normal black 2-phono cable as a digital interconnect. Then, I upgraded to the black 2 waveform, and there was a huge increase in every aspect of the sound, especially detail.

Exceptional cable 10/10. As a side note, I have the whole cinema system in black 2 speaker and phono cables, with black ultra jumpers and diamond jumpers at the speakers, and the sound is exceptional and riveting.

It is very hard to stop listening to it.

Tellurium Q…. Say no more ! 9 April 2022
Right out of the box, I noticed greater bass broth and impact with enhanced separation and instrument detail and texture, and the cable it replaced was no slouch either.

Very happy with this upgrade
