Power Cables

Some people question why it’s worth spending money on the final couple of meters of power cabling, when the electricity available from a wall socket has already travelled miles to get to that point.

The fact is, those final meters are critical. An ordinary ‘kettle lead’ like those supplied free with hi-fi components contains only rudimentary conductors and connectors – the bare minimum to ensure the item works. Cables like these act as aerials to EMI/RFI, which affects the performance of audio equipment, and are not built to maintain electrical integrity to the standard required for high-quality audio reproduction.

This is important because mains electricity is the raw material from which the audio signal that drives your speakers is fashioned. If the electricity powering your audio equipment is affected by noise, the sound waves that reach your ears will suffer from consequential distortion.

A high-quality audio power cable is tailor-made to suit the current requirements of audio equipment, from source components to power amps, with special high-current cables for big, current-hungry amps. They are also designed to protect the integrity of the electricity they carry, minimising distortion and preventing the ingress of EMI/RFI. A simple A/B listening test between a standard ‘kettle lead’ and a specialised audio power cable like those made by IsoTek shows the difference this simple upgrade can make.

Of course, if you really want to maximise your system’s performance, you should consider one of IsoTek’s award- winning power conditioners. But if you do, don’t forget the cables; running a high-quality mains conditioner without power cables of sufficient quality is tantamount to mopping the floor then walking on it with muddy shoes.

Not all cables are created equal
Cable design – be it interconnect, loudspeaker or power – must consider conductor purity, dielectric specification, geometry of the overall assembly and termination. Performance reduction comes in various forms – in signal- carrying cables, it manifests as a relatively benign loss of information or a tonal change to the character of the music. In power cables, restrictions occur due to poor conductivity, impure copper, low conductor size and inadequate dielectric choices, especially when combined with cheap termination using low-grade brass.

IsoTek power cables pay deep consideration to all areas of design and construction. For conductors, the highest-purity 99.9999% oxygen-free copper is the baseline standard, with more expensive designs using silver plating, Ohno Continuous Cast copper and even deep cryogenic treatment for optimum conductivity. The size, quantity and configuration of conductors advances as we progress through the range, as does the level of shielding and the materials used for termination.

The result is a seven-strong range of power cables, each one engineered to deliver exceptional performance at its price point. From the low-cost, high-performance EVO3 Initium to the extraordinary EVO3 Ascension, there’s a cable to suit every system and every pocket – simply arrange an audition at your nearest IsoTek dealer to hear the difference for yourself.

 

Products

EVO3 Initium

EVO3 Initium is IsoTek’s new entry level power cable designed to offer high quality performance at an extremely fair price.

EVO3 Optimum

A high quality FEP provides 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 give internal strength and reduce microphony.
