LC-3 MK3+ is a high quality power cable, designed to power Hi-End audio and video systems. The power cord was designed using experience gained while designing the reference power cable LS-1. The LC-3 MK3+ is also available as optional equipment for GigaWatt power strips and power conditioners.
In the improved construction of the cable we used a new conductor with high conductance and a new isolator. Lossless flow of energy is made possible by the strands of the cable made up from eight solid core conductors with 1,5 mm2 cross-section each.
Those are made from 99,997% pure copper (OFHC C10100), additionally subdued to an annealing process, which allows them to gain uniform structure and better conductance.
The isolation of the conductors is made from elastic polyethylene with lowered dielectric constant. The LC-3 MK3+ has three times the cross-section of the working wires compared to the LC-1 MK3+. The external sheath is made from soft PVC, which allows for increased flexibility of the cable. Another protection is given by the plastic braid, wear resistant, and equipped with an anti-static mesh, which prevents the occurrence of static loads. The very high cross-section of the cable guarantees negligible resistance and almost unlimited current flow. On the other hand, its comparably high intrinsic capacitance, which is caused by the cable geometry and the characteristics of the dielectric, stands in for great filtering and damping capabilities for a wide range of interference. The wires of the cable are protected by a static shield, made from laminated aluminum foil with an internal, copper flow wire. The tight construction of the shield covers 100% of the surface of the cable, perfectly protecting against all kinds of external interference. In addition the shield prevents the appearance and spread of internal interferences as well as returns parasitic currents to the ground wire. In the construction of the cable a lot of attention was devoted to the reduction of the vibration created by the electromagnetic field induced around the conductors. All parallel twisted wires and the shield are covered with elastic material damping the unwanted vibration.
The cable is equipped with high quality, proprietary plugs. Those plugs have a very durable construction, guaranteeing longevity and reliability. The connectors allow for steady current flow from the power grid. Their solid contacts were made from brass, gold plated, what guarantees low transfer resistance and large amount of connection cycles without compromising the cable parameters. The contacts of both plugs were de-magnetized and cryogenically treated. All conductors are connected without the use of solder, and the connections to the plugs are bolted, what guarantees high reliability and optimal functionality.
The LC-3 MK3+ will work best as a power cord powering the whole system. Due to its high cross-section it is especially recommended for places with high current demand. This cable is also available in high current version, LC-3HC MK3+, being the optional equipment of the flagship power conditioner PC-4 EVO+. The cable is then terminated with a PowerCon 32 Amp plug, capable of transferring stable current of 32 A. In boxed version, the cable is packaged in an ecological, wooden box.

In the opinion of specialist audio magazines the devices from GigaWatt are among the best in the world, both in terms of effectiveness and manufacturing quality, and even surpass the standards used in the branch setting new masters. This statement is confirmed by many reviews and prestigious awards given to GigaWatt products. You can find some of them below:

“GigaWatt cable evidently improves the clarity and contours of the sound, especially in the bass range. The effect of “detaching” the sound, especially in the transmission of rhythmics and information given in the full band, will be very audible mainly in well configured audio systems. “”The LC-3 MK3 + allows you to play the music easily – I would describe this effect as a kind of “unchoke” of the sound in the low tones range and improvement of the presented dynamics at the macro scale. Despite the fact that the sound has become more and more popular in the reception and the order has appeared not only in bass and midrange, but also in the range of treble, I additionally heard an improvement in dynamics. Spectacular loudness jumps during listening to classical music, and sudden changes in rhythmics, especially in jazz, were transmitted with a better selection of the beginning and end of the reverberations of individual sounds. “

“The difference in sound, compared to my usual cabling was noticeable, with tube as well as with solid state amplifiers. The LC-3 Mk3 provided more pleasure from listening”
“Having at my disposal four very high quality cables LC-3, for 900 Euro each, I connected them to my power amplifiers. Two to the Primare power amps, powering the bass modules of my Triangle Grand Concert and two to the Air Tight monoblocs, which amplify the midrange segments.”
”You do not need to have trained ears to hear, that the amplifiers worked on highest level: music gained more saturation. Localization and the energy of the recordings improved, the sound stage became wider and deeper. I was happy with this setup for a few days, knowing that I would not want to return to my previous combination of cables: the enrichment of the sound was obvious. The sound was a tad warmer than with my own cables, but I got used to that very quickly and felt comfortable.”

“The change was easily perceived – higher dynamics, more powerful, better controlled bass foundation, openness of the sound as well as a general impression of sound being cleaner. Those were of course no “giant” changes, but clear and very positive.”
“There was a certain calming down of the sound, not related to limitation of dynamics, but to further tidying of the sound and showing it against a darker background. The definition of bass, although very good before, was further improved, the sound, as I mentioned before, tidier, was also more dynamic, in the sense of reproducing the dynamic changes better (also the small ones) and showing a greater dynamic scale. I had the impression, that the whole system reproduces the music with more breath and swing.”
“The Gigawatt LC-3 Mk3 is a cable, which does not limit the powered system or device. It fares very well, when it has to master high power demands. It gives an effect of freedom, dynamics and cleanness of presentation. The effect of the black background exposes even the smallest details and underlines the timbre of the instruments and vocals. What is important, with the imposing dynamics you get also a sense of quieting down, sorting out of the presentation, what can be fully appreciated changing from another cable (for example the version Mk2) to the tested one (or even better, when returning to the “lesser” power cord). The power amplifier powered directly by this cable gains expression, freedom and dynamics of sound.”
