The Matrix Reference tested

Today, I’m diving into the testing phase with the Matrix ‘Reference’ power cable from Perkune Audiophile Cables. Over the last two years, I’ve had the pleasure of evaluating an array of audio cables. Also, their consistent track record of positive performance has stood out. And time and time again, their cables have demonstrated an ability to improve the sound output from the loudspeakers.

In my continuous pursuit of audio excellence, I’m delighted to introduce the Matrix Reference – a groundbreaking evolution in cable technology that surpasses the capabilities of its predecessor, the Matrix PRO power cable.

Matrix Reference

At the heart of the Matrix Reference is the innovative integration of a Ferrite core within the plug. This advanced feature serves a dual purpose: firstly, as a magnetic suppressor, effectively minimizing electromagnetic interference and elevating the cable’s capacity to deliver a pristine and accurate audio signal. Secondly, by housing the Ferrite core directly inside the plug, conductivity is optimised, ensuring unparalleled performance with direct and unimpeded contact on the conductors.

Complementing this breakthrough is the meticulous incorporation of a slim silicon sleeve that isolates the plug body from the cable. The silicon sleeve, acts as a shield, preventing unwanted vibrations and external interferences from affecting the cable’s performance. Also, this isolation guarantees the audio signal remains pure and unaffected. Allowing the Matrix Reference to provide an uncompromising and immersive listening experience.

Amplifier used


To assess the capabilities of the Matrix ‘Reference’ power cable, we opted for the Rotel Michi X3 Series 2 audiophile Integrated Amplifier. My initial encounter with this amplifier in June 2023 left a lasting impression. As it demonstrated an ability to deliver precise and detailed audio information. Revisiting it for this evaluation only reinforced my appreciation for the amplifier’s prowess.

The Rotel Michi X3 Series 2 proved itself as more than just a powerhouse; it excelled in offering an expansive soundstage adorned with remarkable details. The amplifier’s capacity to reproduce audio with accuracy was striking, providing a captivating and immersive listening experience. The wide soundstage, coupled with intricate details, contributed to creating a sonic landscape that truly captivated the listener.

Loudspeakers used


For the testing phase, we employed loudspeakers from Apertura Audio. Who are a distinguished French company boasting over 40 years of expertise and operating under the umbrella of Stentor SAS. The choice of Apertura Audio loudspeakers reflects a commitment to quality and a rich heritage in audio engineering.

Driving these speakers were the Matrix ‘AIR’ speaker cables, an integral quality component chosen for its capability to deliver high-fidelity audio signals. And, the use of the Matrix ‘AIR’ speaker cables contributed significantly to the overall immersive listening experience. The cables facilitated a seamless connection between the amplifier and the loudspeakers. Ensuring optimal signal transfer and, consequently, an audio experience transcending conventional boundaries.

Cable testing

For the comprehensive audio cable testing, I curated a diverse selection spanning various genres and lasting approximately three hours. The exploration began with Diana Krall’s ‘Temptation,’ a piece that unfolded with a unique depth and transparency. The music, when channeled through the Matrix ‘Reference’ power cable, Rotel Michi X3, and Apertura Audio loudspeakers, revealed tones of unparalleled beauty. Details and micro-details surfaced with newfound clarity, unveiling a vibrant and colourful sonic landscape. And It felt as though the music was not just playing but coming to life. Also, the interconnect cables seamlessly conveyed every nuance from Diana’s lips to the loudspeakers, leaving nothing behind.

Transitioning to ‘The Vanishing of Peter Strong,’ performed by ‘Yello’ my favourite band, marked yet another ascent up the auditory ladder. The experience was immersive to the point of discovering nuances previously unheard. Also, the music exhibited a remarkable balance of power and smoothness. As each note seemed a deliberate step up in sonic quality. The sound enveloped the space, creating an atmosphere where the music seemed to transcend its recorded form. And beckon me into Peter Strong’s world.


During an extensive three-hour testing session (typically, our listening sessions last one hour), the Matrix Reference power cable not only met but exceeded all of our expectations. And, this comprehensive improvement solidifies the Matrix Reference power cable as a true game-changer, offering an instantaneous and substantial upgrade to your audio enjoyment.

Also, pairing the Rotel Michi X3 Series 2 with the Matrix ‘Reference’ power cable aims to further amplify this exceptional audio experience. The goal is to discern how the cable enhances the already impressive performance of the amplifier, With a keen focus on any nuanced improvements in sound reproduction, detailing, and overall sonic presentation. This collaboration promises to be a fascinating exploration into the synergies between cutting-edge amplifier technology and the innovative design of the Matrix ‘Reference’ power cable.


The cable testing held at Garso Namai, Kauno g. 31, 03215 Vilnius, Lithuania. Tel (8-690) 22322, and always a pleasure to test in their facilities.


In light of this, I wholeheartedly recommend both the Rotel Michi X3 Series 2 amplifier and the Apertura Audio loudspeakers for any audio enthusiast seeking an elevated and immersive sound experience. The combination of these components, complemented by the Matrix ‘Reference’ power cable and ‘AIR’ speaker cables, promises to satisfy even the most discerning audiophile’s expectations.

The Matrix Reference isn’t just a cable; it’s a testament to pushing the boundaries of what’s achievable in the realm of audio excellence. Experience the remarkable difference and elevate your listening pleasure with the Matrix Reference power cable – where innovation converges with unparalleled performance.
