This unique design consists of deep cryogenically treated silver plated Ohno continuous cast copper conductors, wrapped in a dielectric of air, with partial FEP contact, before a further extruded FEP sleeve seals the construction. Each of these individual conductor assemblies are wrapped in Mylar with a further OFC shield before being given a slight rotational twist with FEP tubes of air.

Ascension drops the noise floor to an inky black level, opens the soundstage with holographic images, air and space and unparalleled micro dynamics. Astonishing.



The conductors are in a parallel configuration with a slight rotational twist. This established technique remains the first line of defence against RFI and EMI rejection.

A) Conductors: 4.0sqmm silver-plated Ohno Continuous Cast copper conductors offer a vastly superior level of purity compared with traditional OFC. Each conductor is deep cryogenically treated down to -196° C. The geometry and metallurgy used in this cable offer superb performance with extremely impressive electrical conductivity.

B) Dielectric: To obtain a dielectric constance close to a vacuum, IsoTek has created a Virtual Air Dielectric offering just 1.0548 dielectric constance. This air barrier is achieved by minimal conductor contact and the use of an FEP (Teflon) bridge. FEP is an excellent dielectric in its own right, with low coefficient, and the first choice for safety in both temperature and electrical insulation.

C) Filler: Clear FEP (Teflon) air tubes surround each conductor maintaining low dielectric constance and cable construction stability.

D) Wrap: Each conductor assembly is wrapped in Mylar to offer individual conductor shielding as well as a further barrier against RFI.

E) Shield: An earthed OFC shield insures maximum RFI rejection, thus preventing common mode noise affecting the live and neutral conductors.

F) Jacket: PVC is used as an outer jacket to give a high degree of flexibility and mechanical strength.

TERMINATION: The Ascension cable is terminated using IsoTek’s bespoke ultra high grade audiophile connectors of solid OFC with pure silver-plated conductors. These offer the highest level of conductivity and quality performance.



As one would expect the internal wiring of any IsoTek product is of the highest standard, ultra pure Ohno Continuous Cast copper solid core conductor strands with silver-plating offers low resistance and high amperage. A Fluorinated Ethylene Propylene (FEP) helix is wound around the conductor before an extruded FEP dielectric protects the conductor and creates a Virtual Dielectric of Air (VDA). This construction gives unrivalled performance and gives the ultimate low resistance, high performance internal power delivery system.

IsoTek’s internal wiring synergizes with the range of IsoTek power cables. One critical but overlooked area is maintaining commonality of design and material properties though an audio wiring loom, be it signal carrying cables or your power cable network.



Every IsoTek product uses the finest grade electrical components, many custom made, using the highest quality metals and materials which are specifically designed for purpose. Quality doesn’t stop at parts but also extends into the PCB designs, which maintain high levels of amperage and extraordinarily low levels of resistance, using up to eight times the general standard of copper prior to pure silver plating.

Internal wiring also uses high purity coppers combined with silver plating, with either Fluorinated Ethylene Propylene (FEP) dielectric or IsoTek’s Virtual Dielectric of Air (VDA), where a FEP tube is wound around the conductor before an extruded FEP dielectric protects this construction giving unrivalled performance and the ultimate low resistance, high performance internal power delivery system.



"While this audio system may not be the most sensitive or have the last word on detail out there, but the IsoTek Ascension really has made a difference.

Does this mean I am going to tell everyone I meet to rush out and spend three-grand on a power cable? Nope. Well, unless they are looking for final ways to eke out the last bits of performance from an already well-synergised system.What I can tell you is that it is very obvious to me that IsoTek are specialists in their field. They design and build products around power.You’ll not find speaker cables or interconnects on their product list, and why should they? They have clearly found what they are good at and they do it incredibly well.The downside to this experience is now I need to test power conditioners! Does it ever end? At this price point, IsoTek's EVO3 Ascension could well find itself up against other ‘money no object’ competitors at even higher price points, and I suspect it may hold its own. IsoTek's EVO3 Ascension is available in UK, EU, US, AU, and CH power plugs, C15 IEC socket only." - JAY GARRETT

"I was sceptical that a mains cable could need to be £3000, and then I tried it. The extra depth to soundstage, increased speed of presentation and reduced noise floor quickly converted me to its magical powers. Ascension is definitely the right name for this product as it allows all areas of music playback to ascend to levels not experienced before and transcends all other mains cables I have yet tried. Now, whether you have £3000 to spend is another matter, but if you’re serious about your music then you might consider it well worth trying it out."

"EVO3 Ascension is not IsoTek’s first cable. Its not even the company’s first ‘real’ cable. But it is ‘born to the purple’; the first cable that will be taken really seriously by audio’s glitterati, who don’t get out of bed for less than £10,000. Highly recommended!" - Alan Sircom
