Ultimate power cord review

Ultimate power cord reviewThis is the Ultimate power cord review. And, I will write that for a good few years I have been testing Perkune Audiophile Cables cables. Created and developed byMr. Paul Goodwin. In fact, I have already listened to most of Paul’s cables – including various prototypes (which eventually came or did not go into the offer). And, from my experience, I know that running your own business has to involve large own costs. And, it is not possible to sell your own official products for free, just like internet quasi-private DIY cables manufacturers.

 The Ultimate

The two-meter Ultimate power cord is one of the latest additions. Paul Goodwin worked for two years developing and designing for a sophisticated audiophile who wanted the best sound. The ultimate range of cables includes silver plated (2.45 g / m) 99.99% OFC copper cables, 24-karat gold-plated connectors, two and three-level AirGap insulation.

According to Paul: “The sound performance of the Ultimate cable has been achieved because the cables conform to a harmonized standard.” (H) for 300/500 V (05), PVC (V) and PVC (V) insulation, with a flexible multi-wire cable core (F). The result is a darker background which, allows the vocals and instruments to offer a better presence, with a clean and natural sound.


The Two-meter Ultimate Power Cord has an industrial (shock and damage-resistant) Schuko plug and latest IEC C-13 / HC5, which provides an even safer connection. Paul says the new power cord provides “Speed, dynamics, improved sound-stage, and darker background”. Perkune audiophile cables offer an upgraded version called the ‘Ultimate gold’ with three-level AirGap insolation.


Cable diameter: 14.0 mm. Conductive conductors: 3 x 2.5 mm copper multi-conductor class 5. Resistance: 0.44 Ohms / meter. Weight: 1.2 kg / meter. Insulation: TI2 PVC. Coat: PVC type TM2. Main guard (AirGap): DERAY-PBFSP. Secondary cover (AirGap): DERAY-PBFSP. Outer sheath: CanuFlex PE-HB. Working temperature: from -40 ° C to + 70 ° C, Normal voltage: 300/500 Volts. Certificate: PN-EN 60228

AirGap isolation

AirGap isolation is a shell construction which has 720 air pockets per square inch of fabric. These air pockets are “trapped” in the material that runs along the length of the power cord. So actually 17,280 pockets of “trapped” air cover the length. The power cord can be covered with one, two or three levels. The AirGap isolation is said to protect against interference. By reducing the negative effects of external frequencies and vibrations. It is worth noting the Ultimate power cord is flexible and easy to apply to any device.

Test equipment

I applied the Ultimate power cord to several amplifiers: Taga Harmony TTA-1000, Unison Research Unico 90, Audio-gd A1 and Pioneer C-90 / M-90. I also used it for the Pioneer PD-70AE and Unison Research Unico CD players. I also connected it with the DAC Audio-gd R-28. A full list of accompanying equipment is available at the end of this text.

The Power Cord

Writing honestly, I do not like to write tests for cables and those who supply in particular. Why? Because the changes in the sound caused by various cables are very discreet. Deeply subtle, and often even ambiguous. This is difficult to define unequivocally.

Cables have such a subtle effect on the sound. You have to “listen” in order to hear something specific. Nevertheless, I cannot write cables do not rebuild the sound structure because they do. However, the description of changes is a derivative of things heard, implied and estimated. A kind of recombination of several physical and sensual phenomena so please remember this.

Sonic impressions

The Lithuanian power cord interacts with the so-called presence and fullness of the musical instrument’s image. Firstly brings them closer, secondly clearing artefacts and thirdly actually cutting them from the background. The sound is more transparent, easier to hear the tones, with fuller, smoother better-marked edges and contours.

Musical message and attack are not dimmed, but underlined and extracted from the recording. You can write the power cord does not lighten or dim the message. It does not add anything, neither the sopranos or the bass. It is simply the optimal transmission of pure a studio-quality signal.

Sound level

General sound, accelerated by the Ultimate power cord passes to a higher level of concentration and energy. The sound now becoming more effective and active. Better definable and more multidimensional, and easier to hear. Mini-details, details, and micro-elements of recordings are more legible (But also dirt and errors of recordings!).

Tonal accents (the trembling of strings, the metal of reeds, the whistling of trumpets, etc.) are more clearly defined and have more internal energy. The same applies to space, which receives a deeper dimension and a darker background. What is very important is precise illumination and disambiguation as well as fixing particular instruments and vocals.

Sound spectrum

The sound spectrum does not feel any coolness or slowing down. All apparent phenomena taking place in the listening room do not tend to reduce speed or energy. Their glow is neither obscured or covered. They are sonically perfectly effective and crystallized like refined sugar!

Interestingly, the Lithuanian power cord provides a slightly more distanced sound (compared to the usual chain). Placing the listener in a hypothetical space a bit more distant from the foreground.

Such a procedure seems to be not helpful in the analysis of sound, but in reality, helps in the reception of music. And somehow allowing the listener to change from the first rows of the Philharmonic to the middle rows. Which is optimal for harmonious and fuller listening.

Thanks to this occurrence, the sound of the hi-fi system becomes closer to the naturalness of music. Not every network cable can apply such qualities, but this can. And undoubtedly is a great advantage.


The Perkune audiophile ‘Ultimate Power Cord’ is a very successful and reliable cable, on which you can depend. Best Audiophile cables Online
