Our take on the brand
The most significant differences compared to the PC-3 EVO+ : – distribution rails made of silver-plated, highly conductive copper (99.995%) with a cross-section of 30mm2 – hydraulic-magnetic switch by Carling Technologies – damping of the housing with a bitumen-polymer composite mat – LC-2 EVO cable as standard
All elements of the conditioner are mounted in a rigid steel-aluminum chassis, which rests on anti-vibration feet, made of solid anodized aluminum, with an additional layer of the company's 3.5 mm thick elastomer. To reduce vibrations transferred to the conditioner, its chassis was additionally damped with a bitumen-polymer composite mat. The front panel of the conditioner, is made of a thick slab of aircraft aluminum, the surface of which, after precise milling, is roughened and then anodized in two colors – black or silver. In the central part there is an LED display indicating the value of the input voltage. The voltmeter is characterized by resistance to distortion and measurement errors caused by higher harmonics, while not generating any interference that could degrade the quality of the voltage filtered by the conditioner. The display, which has a fade-out option, is white as standard. Nine other colors are available upon request.
The PC-3SE EVO+ has six, top-quality proprietary output sockets, with contacts of large surface area. The brass contacts are technically silver plated, with no intermediate metal layers such as copper or nickel, which could introduce unfavorable series resistance and voltage drop. The conditioner is also equipped with an additional circuit that signals if the device is incorrectly connected to the mains. Its activation is indicated by a red LED located on the back, informing of incorrect polarity of the conditioner's power supply or a defectively connected grounding.
The design of the PC-3SE EVO+ is based on a unique eight-stage filter architecture using the most advanced, uncompromising components. The conditioner is equipped with three autonomous filtering branches, serving separate three sections, consisting of four outlets each. This allows isolation of individual loads from mutual interference generated by connected devices using a common power line. The innovative two-stage power distribution system is based on massive distribution rails made of silver-plated OFHC C10100 oxygen-free copper bars of 99.997% purity. The first stage allows for lossless and even voltage distribution to the individual filter branches. The second stage delivers current directly to each quart of output sockets.
The company's semi-multistrand conductors with enlarged cross-section, made of silver-plated oxygen-free copper insulated with Teflon, are responsible for the transmission of current between the individual modules. These solutions ensure even and stable power distribution regardless of the load on the individual outputs of the conditioner. The company's anti-interference capacitors are responsible for the essential filtering of interference, and are manufactured to GigaWatt's strict specifications. Surge protection of the conditioner is provided by high-end elements with increased absorption and aging resistance.
Our summary
Product Strengths

Our take on the brand
The Denali 6000/S v2 features patented technologies and proprietary components that are unavailable in any other competitive product. The Denali supplies unrestricted peak current to multiple components while dramatically reducing noise from the power line and intercepting noise from component-to-component interactions, isolating each component in the system. The Denali 6000/S is designed to provide the finest performance available, at a price-point intended to embarrass the competition.
The QR/BB™ module possesses the ability to act as an electric charge reservoir, meaning it stores and releases energy in a manner that improves a component's access to instantaneous current. Dynamics are actually improved reducing any sense of dynamic strain often heard from amplifiers that are connected with lesser power cables. The sonic result is a lifelike presentation of timing and dynamic contrasts in sound that cannot be replicated by ANY other means.
Traditional power conditioners are designed to block incoming noise from outside the home, but do not address the noise that is generated by the electronic components themselves. CCI™ (Component-to-Component Isolation) is one of the most significant but often overlooked aspects to power system performance. The CCI™ filter consists of a proprietary multi-stage filter that reduces electrical noise and interference generated by a component's power supply.

Our take on the brand
The compact depth of the enclosure reduces the footprint of the unit. More space at the rear allows for easier installation and cable connection. The conditioner has a rigid steel-aluminum chassis, with a modular design, allowing the installation of sockets of different standards. The chassis rests on anti-vibration feet, made of solid anodized aluminum, with an additional pad of the company's 3.5 mm thick elastomer. Modules with electronics have internal elastomer shock dampers to prevent the transmission of vibrations to the filter elements. In addition, the top cover is dampened with a bitumen-polymer composite mat.
The front panel of the conditioner, with a new design, is made of a thick slab of aircraft aluminum, the surface of which, after precise milling, is anodized in two color options – black or silver. In the central part there is an LED display indicating the value of the input voltage. The voltmeter is characterized by resistance to distortion and measurement errors caused by higher harmonics, while not generating any interference that could degrade the quality of the voltage filtered by the conditioner. The display, which has a fade-out option, is white as standard. Nine other colors are available on request
PowerControl has twelve, top-quality proprietary output sockets, with contacts of large surface area. The brass contacts are technically silver plated, with no intermediate metal layers such as copper or nickel, which could introduce unfavorable series resistance and voltage drop. The conditioner is also equipped with an additional circuit that signals if the device is incorrectly connected to the mains. Its triggering is indicated by a red LED located on the back, indicating that the conditioner's power supply is incorrectly polarized or the grounding is incorrectly connected.
