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.

Atlas Hyper Achromatic Bi-Wire Speaker Cable - 4 x Z-Plug to 4 x Z-Plug 2m Pair (Special Offer)

 

This cable is terminated with 4 x Atlas Z-Plugs on the amp end, and 4 x Atlas Z-Plugs on the speaker end.

Replacing a well-loved sibling the new Hyper Bi-wire takes over where the older product initially sat many years ago, at a lower price point. Customers love Atlas Bi-wire cables due to the delivered performance, solid core treble/mid and stranded bass, all four cores in a single jacket.

The new Hyper Bi-Wire speaker cable aims to get customer back in love with Bi-wire and with advances in dielectrics and the new Achromatic plugs delivers performance, substance, and style.

The Hyper Bi-Wire cable employs conductors comprising 72 0.25mm² high-purity OFC (Oxygen Free Copper) strands encapsulated within a carefully selected high-efficiency PTFE (Teflon™) dielectric coating. The resultant conductor is embedded within an anti-vibration cotton filler.

 

Features :

  • Achromatic Z-Plugs
  • OFC Conductors
  • PTFE Dielectric
  • Multi-core + Solid Core

Achromatic Plugs

Atlas’s expert electro-mechanical knowledge has led to the innovation of the next generation of banana plugs known as the ‘Atlas Achromatic Z Plug’, Atlas has focused on improving performance to create a higher performance starting point for their speaker cables as well as eliminating variability in performance. This has been achieved by refocusing on materials and the assembly processes.

Atlas has made 4 key changes with the Achromatic Z plug. Firstly, the barrel of the Achromatic Z plug features a high stability ABS material. This is strong, stable and of superlative surface quality.

In addition, there is also an improvement to the plug's contact resistance achieved by improving the compliance of the beryllium copper contact leaves featured on the Achromatic Z plug. Beryllium copper offers excellent conductivity of signals.

The third change was to upgrade the manufacturability of the plug for pneumatic tool processing.

Finally, there is a reduction in the overall mass of the Z-Plug by 35% which has shown to improve signal transmission.

The above changes mean a solder-free, low mass, self-cleaning, recyclable Z-plug with a non-conductive body.

 

Oxygen Free Copper (OFC)

OFC is produced through an extrusion process which takes place in an oxygen-free-inert-gas atmosphere. This leads to a reduced oxygen content (10 ppm) when compared to Tough Pitch Copper (TPC) and an improvement in conductivity which typically measures in at between 0.5% and 2% greater than TPC. The OFC process therefore produces a much higher quality audio cable than the TPC process. High purity conductors sound clearer than their unprocessed (TPC) counterparts because there are fewer crystal boundaries present to cause signal degradation.

PTFE Dielectric

PVC (Poly Vinyl Chloride) is cheap to produce and, as such, is the most commonly used insulation in AV cables. However, PVC is the worst quality insulation a Hi-Fi or AV signal can encounter as its high loss causes a significant reduction in signal velocity. PVC is better suited to power cables and should be avoided in Hi-Fi and AV signal cables.

Other dielectrics in common use are Polyethylene, Polypropylene and Polytetrafluoride Epoxy (better known as PTFE (Teflon™) or Teflon,) and the new and unique Atlas (PTFE).

Microporous PTFE (Teflon™) is a unique, low density dielectric material, phase stable at room temperature, which offers significant performance improvements over solid PTFE (Teflon™) dielectric designs.

The table below shows the properties of a selection of dielectrics. Though not used as a dielectric in Atlas' cables, PVC is included for comparison purposes.

Multi-core + Solid Core

A pair of identically matched conductors (one for signal path, the other acts as the return conductor) enclosed within a non-conducting screen.

 

 

"With the cable connected between valve monoblocks and transmission line loudspeakers, I kick off testing with Beethoven’s Symphony No.9 performed by the Berlin Philharmonic under the baton of Herbert Von Karajan. After the quiet introduction, the music explodes into an exuberant crescendo. The Hyper Achromatic has no problem with the massive dynamic range of this recording, and there is no sense that the cable is struggling to keep up. When the singers join in for the final movement, Ode To Joy, they are really distinct and never blur together, which can all too often happen with lesser cables." - (Read More)

Hi-Fi Choice Recommended - February 2021

"There’s no doubt in my mind when using the new Hyper cable that the first track I listen to has a significantly improved bass extension. The Chromatics’ Sound of Silence has a heavy double bass line at the beginning of the track and I can clearly hear the deeper sound in my KEFs. It is really quite nice to hear a bit of ported bass that I know and love after the precise and wonderful control of PMC’s twenty5 22i standmount speakers I reviewed last month. To confirm my thoughts on the cables, I go for a bit of Billie Eilish with Bury a Friend and All the Good Girls Go to Hell. My initial findings are reinforced as I peel myself off the wall." - (Read More)

Frequently Asked Questions

Start by considering your amplifier and speakers. For short runs or compact systems, basic oxygen-free copper cables may suffice. But if you're after tighter bass, better detail or a wider soundstage, an upgrade to a higher-quality cable, like those from Chord Company, AudioQuest or Atlas, can make a noticeable difference. For personalised recommendations, speak to our consultants here.
Loading...
Yes. Bi-wire cables separate the signal paths for high and low frequencies, which can improve control and reduce interference in compatible speakers. Single-wire cables are suitable for most systems, but bi-wire setups can offer sonic gains if your speakers and amp support them. Alternatively, you can use single-wire cables with matching jumper cables on bi-wirable speakers.
Loading...
Higher-end cables often use better conductors, insulation materials, and terminations, which can reduce signal loss and interference. Whether it's worth the investment depends on your system's resolution and your listening environment. Our team can help you choose based on your priorities.
Loading...
Yes, cable length can influence performance. Longer runs can introduce resistance and signal loss, especially with thinner cables. Where possible, try to keep left and right channel lengths similar, and choose an appropriate gauge for the distance.
Loading...
Jumper cables replace the metal links between binding posts on bi-wireable speakers. Stock jumpers can limit performance, while high-quality alternatives preserve signal integrity and improve coherence across frequencies. When replacing your manufacturer supplied links, we recommend to use jumper cables of equal or better quality than your speaker cable.
Loading...
All cables matter, and your system will require good quality cables for all of it's connections, however, if you were looking for the cable which will make the biggest difference, then we would recommend looking at the power cables from your wall socket, to your distribution block and/or amplifier. More often than not, we hear from customers, manufacturers, and our own tests that higher quality power cables can have a significant impact of the quality of your system.
Loading...
This entirely depends on your current system and your expectations. You could have a decent pair of speakers which are not matched correctly with your amplifier, or vice versa. Similarly, you may want a new source of media to listen to. There are also options to upgrade other aspects of your system, such as the power, isolation or cabling to get the most out of your system before upgrading the traditional components. The best way to find out your own upgrade path is to contact our consultants and we would be happy to help you.
Loading...
In short, yes, although, this depends on the quality of the cable and your speakers/amplifier. High quality speaker cables tend to be manufactured with 4 key areas, their conductor, dielectric, shielding and geometry. Each of these areas can optimise signal retention from your amplifier to your speakers. Cheaper speaker cables can use lower quality conductors (tin-plated copper or even steel-clad copper), with basic dielectrics (PVC), no shielding and minimal strands with no geometry. More expensive speaker cables start to introduce higher quality conductors (Oxygen-free Copper, Ohno Continuous Cast Copper, Silver-plated Copper or even Pure Silver), better dielectrics (XLPE, PTFE, Teflon etc.), different amounts of shielding (foil, ofc-braid, carbon etc) and various geometries (solid-core, different twists, higher gauges etc.). There are diminishing returns to consider between your speaker cable and your system, as well as the potential of bottle-necks in your system if you use a lower...
