what's this?

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 or BFA-only plugs. (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.

Equipment Review - Hi-Fi World - February 2017

“All cables sound different. But the best add as little of their own character as possible to the system so you can hear the essential qualities of the amplifier and loudspeakers. That is just what the Supremus does. Fitted between a Naim NAP 250 DR amplifier and a pair of Spendor D7 loudspeakers they had the ability to open up the soundstage by extending each end of the frequency spectrum.” (Read More)

Equipment Review - Hi-Fi World - February 2017

 

“Some running-in was required as the early sound was slightly lumpy and closed-in. Driven from Naim NAP500DR and NDS streamer, it did not take long to appreciate the many virtues of this design, namely a powerful, very tuneful and slam-capable bass, and a deep and truly spacious soundstage, which was well illuminated with much detail.”

Cryogenic Treatment

The improvement in physical properties of copper when cryogenically treated results from the elimination of dislocations in the material's microstructure. Trumpets and other brass instruments have been found to produce a better tone after Deep Cryogenic Treatment and it is also used to treat guitar and piano strings.

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.

Termination:

This cable is professionally terminated by QED's engineers using a dedicated Rhodium plated, locking design banana and spade plugs to ensure maximum surface contact between the plug and terminals. Utilising QED's propriety Airloc™ technology for an oxygen free, cold weld connection made for life. AIRLOC is QED's specialised loudspeaker termination method and offers the very best termination with QED speaker cables. This is a solder-free, airtight fusion between the cable and plug offering optimum signal transfer, excellent signal quality and perfect long-term performance.

QED’s AIRLOC banana and spade plugs deliver a superior performance over many plugs offered by rival manufacturers for the following reasons. Firstly, the plug is crimped around the conductors under high pressure using a special tool supplied by QED. No soldering is used and as a result the conductors are in contact with the plug 360 degrees which maximises the surface area contact. Furthermore, the banana plug itself is in contact with the binding post again at 360 degrees. The net effect of this is it maximises the signal transfer from the plug into your equipment and hence a superior performance. When bare wire is used not all the conductors are in contact with the binding post and as a result some loss occurs.

Every cable is hand-crafted to the highest possible standard after which it is rigorously tested. Only then will it finally be approved by a member of the Cable Quality Team.

 

How to Order

From the dropdown menus' above, simply select the length of cable, the type of plugs required at the ‘Amplifier end’ and ‘Speaker end’ and click on the 'Add to Basket' button to add the item to your basket. Your cable will be dispatched as soon as it has been made by Future Shop's or the manufacturer’s engineers and has completed the specified burn-in process (if any), subject to Future Shop’s Terms & Conditions and stock availability.

Free Cable Burn-In Service Option Using The Nordost Vidar Machine

 

Please Note: We are unable to burn-in cables with stripped bare ends or BFA plugs. Cables are burnt-in for the selected time period AFTER your order has been processed. Custom-length cables are burnt-in for the selected time period AFTER they have be terminated by the manufacturer or our engineers. 

Our cable burn-in service is a non-chargeable service and is provided by Future Shop at its discretion. We will attempt to fulfil all burn-in requests for the specified time periods. However, during extremely busy periods, we regret we may not be able to meet demand for all requests due to the limited connections available on the Nordost Vidar cable conditioning machines.

We are pleased to offer a free cable burn-in service for this cable when purchased through Future Shop. The Nordost VIDAR cable burn-in machine combines three distinct functions all in one operation:

  • It neutralises charges that build up around the cables and the insulation
  • It provides a very wide band and deep conditioning into the conductor core, which produces changes in the way signals pass through the metal.
  • It ultrasonically conditions the surface of the conductors.

 

Nordost Vidar Burn-in Machine

 

The VIDAR uses a proprietary combination of composite and complex signals to condition the cables. Parts of the signal oscillate at ultra-low frequencies, while other parts are in ultra-high ranges which extend beyond the range of video frequencies. The signal bounces in a ping-ping ball-like fashion from one end of the cable to the other. During the burn-in process, ultra-low frequencies penetrate deep into the core of the cable. The ultra-high frequencies zip along the surface. This method of signal transmission is set up to beat harmonics, or heterodynes, between the two complex waveforms. In the digital domain, this would be referred to as aliasing products. These beat frequencies penetrate all layers of the cable.  

The design of the circuitry also has a unique feature which drives electrons above the conductor into the dielectric (or insulation) area. The VIDAR not only sends ping pong signals along the cable, it also sends a similar signal from the centre core to the outer shield in the case of interconnect cables. This function neutralises the electrical charges discussed above.

So, what does that all mean to me?
The end result of conditioning cables with the Nordost VIDAR is improved sound staging, increased detail, and an overall more musical presentation.
