IsoTek EVO3 Optimum Power Cable
Construction
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
3.0sqmm silver-plated Ohno Continuous Cast copper conductors offer a vastly superior level of purity compared with traditional OFC. Each conductor strand is of an innovative square-shaped configuration. The geometry and metallurgy used in this construction offers superb performance with extremely impressive electrical conductivity.
B) Dielectric
Teflon FEP dielectric (insulation) is chemically inert and has a very low dielectric constant over a wide frequency range. FEP possesses a very high degree of stress crack resistance and a low coefficient of friction making it an exceptional dielectric. FEP is the first choice for safety in both temperature and electrical insulation.
C) Filler
Cotton filler has been used to give the cable internal strength and reduce microphony. Cotton also possesses excellent dielectric properties, the best of any solid material.
D) Wrap
A Mylar wrap is used to secure the construction and offer a barrier shield prior to the application of a flexible PVC jacket. The addition of the Mylar and cotton form a buffer with the PVC so as to maintain exceptional dielectric properties.
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.
The Optimum is the fourth of IsoTek’s high-performance power cables to be upgraded to the new advanced EVO3 (Evolution 3) version, and is clearly positioned at the top of the range.
The new EVO3 Optimum delivers radical advances over its predecessor, the earlier GII version. Cutting-edge thinking in terms of conductor geometries has been combined with excellent materials to develop a cable of superlative quality.
At the Optimum’s core are three silver plated copper conductors made from Ohno Continuous Cast (OCC) copper. The OCC process for refining copper, developed and patented by Professor Ohno of Japan’s Chiba Institute of Technology, gives a vastly superior level of purity compared with traditional OFC copper. The benefits for audio and AV applications include outstanding electrical conductivity along with improved flexibility and resistance to fatigue and corrosion.
Each of the three 3.0sqmm conductors features a new and innovative square-shaped configuration of 40 strands, each strand also being of square cross-section. This unique design provides an enlarged inter-strand contact surface, further enhancing electrical conductivity.
A high quality Teflon FEP dielectric (insulation) is extruded over each conductor, providing a very low dielectric constant over a wide frequency range. The three conductors are given a slight rotational twist to aid RFI and EMI rejection, and are then surrounded by a cotton filler which, as well is adding internal strength and reducing microphony, also possesses superb dielectric properties – similar to FEP. The whole construction is then double shielded by first enclosing it in a Mylar wrap to provide an additional dielectric buffer, before applying an active OFC copper shield for maximum rejection of high frequency interference. A durable, heat-resistant PVC outer jacket gives a high degree of flexibility and mechanical strength.

Caring for your Speakers and Amplifiers
To Keep your equipment safe these are some best practices to note. Please be advised that this is only to reduce the risk of misuse and is not an exhaustive list.
Speakers
- Speaker terminals are marked red and black, ensure your amplifier to the speakers are wired on the same colours
- Ensure no loose speaker wire from the red touches a loose wire from the black as this will lead to a short circuit and damage either the speaker, the amplifier or both.
- Not all speakers are designed to play at max volume, kindly consider the pairing of your amplifier and speakers
- Speaker cabinets cannot be replaced please handle with care.
AV & Stereo Amplifiers
- If your amplifier has HDMI ports, ensure all devices are off before plugging in the HDMI cable
- Turn off the amplifier before swoping out or adding speaker cable
- Amplifiers generate heat, place them in a well ventilated space. if possible avoid having anything on top of the unit.
- adding a surge protector can assist with power dips which are likely to damage your devices. Isotek and Furman are industry standard.
- Dusty environments can sometimes lead to accumulation of dust in the electronic components that might affect heat regulation
Shipping & Returns
- Free shipping on orders over R500 within the country.
- Standard delivery within 2–5 business days. Delays will be communicated. This might vary slightly depending on your location.
- Return items in original condition for a full refund. (unopened state)
- Returns that are open/unboxed will be subject to a handling fee. Refunds will only be processed after testing the unit.
