Fantastic audio cable

Fantastic audio cable testedEight years ago, I was looking for audio cables. And I wanted to find an expert in the audiophile field, and find a fantastic audio cable. Also, I was fed up trying different audio cables and wanted to improve my audio system sound. And I know a tall order, but started to read audiophile cable reviews in the forums. Because of my desire to improve my audio system was strong. After a few days of looking, I read about an Englishman located in Lithuania. And it appeared this person knew what he was doing when it came to sound. And, as a result, sent an email to the address given in the review and contacted Mr Paul Goodwin. 

 Audio cable

I found a review on a speaker cable written by a review expert in Poland was fascinating. And I saw he had tested other lines made by Paul. And I understood Paul offered a wide variety of cables which was what I wanted. Furthermore, the price of the power cable was perfect, and excellent value if the power cable performed as well as the review from Poland. The review was written by Mr Ludwig Hegel from Stereo i kolorowo in Poland.

Power cable

After a few emails, I decided to order a three-meter power cable. And the cable was to become the heart of my audio system. Also, Paul explained how the cable worked in great detail and gave examples from satisfied customers showing their results. And making me feel I was in safe hands.

And depending on the results, the power cable would undoubtedly become the base of my system. I was certainly expecting a fantastic audio cable, and it proved to be as expected upon arrival. And the power cable was more than I expected in terms of performance and dynamics. Also, I realised that I had found the person I wanted to work with to build up my audio system. And this is the result of my system fours years later.

Audio system

The picture shown on at the top, is my audio system in Norway. And I am delighted with the performance of the system. Every person who listens is amazed at the quality and cannot understand why it sounds so good. And I have included a list of  the component I use and also the audio cables and Power cables.

Beethoven concert grand reference

The Beethoven Concert Grand reference is a no-compromise loudspeaker. And breaking grounds in setting new standards in state-of-the-art music reproduction. Also to say only the design goals for such a speaker were high efficiency. Having outstanding dynamic range, with excellent low bass extension. And ultra-wide bandwidth from a reasonably compact enclosure miss the more significant point. 
Beethoven’s overriding goal, to produce music on a compelling scale to transform the listening room and transport the listener. And at the heart of the design stand Spidercone drivers. One 6 inch midrange and three 7 inch woofers. And all with the patented flat Spidercone within new construction. 

Spider cone 

The plane surface of the spider cone offers the advantage of precise, piston-like movement. Any diaphragm should move in and out as one unit. And not as a quivering mass of uncorrelated vibrations. It should move as an excellent piston. The flat cone is exceptionally stiff, with bracings of a height of 18 mm (bass) and 14 mm (mid). Also light, respectively, further reinforced by glass fibre in the new X4P mixture.
The rear side bracings are constructed so the whole impulse energy is allocated evenly via the entire surface of the flat cone. Thus, every square centimetre delivers the same impulse as its neighbours. Resulting in revolutionary impulse response control.

As the cone/diaphragm construction builds upon a giant voice coil, the radiating surface in its middle is large. Thereby making it a significant sound determinant. The Five cm area is now an inverted dome made from woven fabric. Which, is double-coated on its rear side. And perfection, achieved by listening to various axial positions. And with extraordinary homogenous results by employing a recessing of 8mm


This 1.1-inch tweeter can reveal even the most delicate nuances. And are most naturally while imparting no stridency at all. Also extending well down into the midrange spectrum.
The crossover circuitry possesses the elegant simplicity of soft filters. Pure first order, 6 dB per octave slopes to Bessel second order. And the essential complexity resulting from listening needed to weave the drivers’ output. All decisions concerning individual components and the circuitry layout were made through extensive listening tests.

The Sort Kone is a directly coupled and mechanically tuned resonance control device. And using a sophisticated new approach to the problem of supporting sensitive electronics. Whereas most equipment, referred to as Isolation devices, completely misunderstands the nature of the problem. The most harmful mechanical energy doesn’t enter the equipment from outside; it’s generated internally by the audio circuits and their power supplies. As a result, transformers, power supply capacitors, even the active devices themselves all vibrate as they operate, And those vibrations occur right where the weak signal is, creating timing errors that smear and distort the music. The Sort Kone, designed specifically, to deal with this threat to audio fidelity.

  • Nordost Sort Kone Isolation Cone
  • Three-part construction employs superior materials in a mechanically tuned configuration

Spike shoe mk2

Blue Horizon’s unique Spike Shoes MKII, made with a machined stainless steel outer casing designed to sit beneath spikes of floor standing speakers. Also speaker stands or other cones. They serve a dual purpose; their chaotic cork and rubber mix protects flooring and aids resonance control. In addition, they enhance sound quality by suppressing resonance that leads to sonically damaging microphony in audio components. It is the second of these functions that sets them apart from other spike shoes on the market.

  • Point Loading100kg
  • Diameter38mm
  • Height (outer)7.5mm
  • Height (centre point)6.5mm
Speaker’s feet

The GAIA isolators are machined units that incorporate IsoAcoustics’ patented design to provide a high degree of speaker isolation. And while resisting lateral movement and oscillations to maintain alignment with the listening position. In addition, internal reflections from the hard supporting surface result in greater sound clarity. Also the soundstage blossoms to open a three-dimensional image of natural, spatial sounds.

Optimal results are heard by installing these units with the logo facing the listening position or rotating 180 degrees to align the isolators with the speaker’s motive forces. And lifting and placing the speakers into position as the GAIA lower isolator will adhere to the supporting surface. When a speaker is placed on a hard surface, secondary internal reflections result. Any artefacts of this smear that is similar in the two channels are perceived to be in the centre. Therefore causing the sound stage to collapse. The GAIA series of isolators eliminates this smear resulting in a larger 3-dimensional sound stage.

Soundcare super spike  

The use of spikes with Hi-fi components improves sound quality. It is also an inevitable fact the use of points damages the surface on which they stand. One has seen numerous attempts to make feet that prevent the disadvantage of damaged floors, but they all render reduced sound quality. The use of spikes gives the best sound! Soundcare® has seriously dealt with this problem and has developed a new SuperSpike that takes care of all good advantages and protects all surfaces. Several high-end producers deliver their products with Soundcare® SuperSpike from the factory. Listening tests in Norway, Denmark, Japan, Germany, England, France and the USA.

Why use Soundcare® SuperSpikes? When the weight of your Hi-Fi equipment concentrated onto a small area, the weight per square unit area increases enormously, providing better contact with the surface on which the unit stands. Resulting in an overall improved sound stage and increased control in the lower frequency register. In addition, Soundcare® SuperSpikes reduce disturbing vibrations and prevent low-frequency noise from transmitting to other rooms. A Soundcare® SuperSpike loaded with a weight of 12.5 kg produces a pressure of more than 6,200 kg pr. sq. cm!

Latest addition:
The Matrix reference Power cable (recently added) is easily the best Power cord I have ever owned. And, has the amazing ability to enlarge the sound in my system, so much so, that it sounds like you did have the whole orchestra in my living room!! Details are excellent defined though the pitch black background and the texture in the music gets a whole new meaning. And, it makes every little detail stand out and almost float in the air around you. 
The vocals are as real as it gets, and the feeling of real live performance is just stunning, to say the least. As for the timing and rhythm, it’s got a life of it own!! 
The toe tapping factor is all time high and it’s so mesmerising you just want to dance with the music. Also, the Bass has now new defined tones and tightness that is absolutely incredible. It really does make everything you listen to absolutely a great experience. And, the musical properties this cable is capable of is a new level. And It just goes to show that power cables really can elevate the listening experience to new dimensions. This power cord is an absolute joy listening to, 

I have a fantastic system, which has taken me over Six years to build. And I love the audio and video quality when listening and watching. It is an authentic cinema experience, and I am grateful for the help and support of Paul Goodwin (and his amazing audio cables) throughout my journey.
