Isotek EVO3 Initium1.5m Premier Power Cable



EVO3 Initium is IsoTek’s new entry level power cable designed to offer high quality performance at an extremely fair price. Initium is a must for replacing all of your free standard black plastic power leads which have been designed down to a price not up to a quality.

Isotek’s most affordable mains cable, the EVO3 Initium was inspired by discussions with high-end electronics companies, many of whom produce audio equipment that retails for tens of thousands of pounds and yet is bundled with poor quality power cords that significantly constrain performance.

This led them to produce a high-quality alternative that respects standard geometric principles, but where every single element is carefully considered, implemented and manufactured to the highest possible standard. There are many brands offering high- quality power cables but these are often very expensive, and also impractical because of their inflexibility and weight. The goal was to attain similar levels of performance from a more practical cable at a fraction of the price.

The EVO3 Initium not only delivers excellent performance, it also represents outstanding value-for-money. No compromise has been made in relation to the quality of parts and materials used in its construction.

Why ‘dirty power’ is a problem

The power that enters your audio components from the wall socket is distorted by the pollution on the mains supply. Sensitive equipment, particularly audio electronics cannot perform to their full potential. The biggest two offenders are Differential Mode and Common Mode mains noise.

Differential Mode Noise

differentialDifferential Mode mains noise is created by all electrical appliances – everything with a power supply, in fact. This includes your microwave oven, your television and your computer, as well as every hi-fi component you own. Take a look around your home and count how many devices you have plugged into your power sockets, each of these will be corrupting the mains sine wave and eroding the quality of the AC power that feeds your high-quality audio system.

Common mode noise

commonCommon Mode mains noise is often referred to as RFI – Radio Frequency Interference. Imagine how much data is transmitted by smartphones and tablets – cheap power cables act as aerials for these unwanted frequencies. The use of wifi and wireless technology is increasing at an exponential rate. Just think about all the data that you send and receive on your smart phone. We are bathed in a sea of Common Mode noise.

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

A) Conductors: 99.9999% OFC conductors offer an exceptional level of purity with enhanced conductivity. They are less likely to fracture or degrade over time.

B) Dielectric: PE dielectric (insulation) is chemically inert and has a very low dielectric constant over a wide frequency range. PE possesses a very high degree of stress crack resistance and a low coefficient of friction making it an exceptional dielectric. PE is a good 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 a solid material.

D) Wrap: A paper wrap is used to secure the construction prior to the application of a flexible PVC jacket. The addition of the paper and cotton form a buffer with the PVC so as to maintain exceptional dielectric properties.

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

: Initium cable is terminated using IsoTek’s bespoke Audiophile grade moulded connectors of solid OFC. These offer good performance qualities.
