OVERVIEW

All the conditioner’s internal components are enclosed in an ultra-rigid, non-magnetic aluminum chassis made of thick sheets of milled aluminum.
To reduce vibrations transmitted to the conditioner, the top cover was additionally damped with a bitumen-polymer composite mat.

The conditioner rests on reference anti-vibration feet – Full Ceramic Isolation System. The task of the system is to minimize the number of points of contact between the foot, and then the conditioner’s housing, and the floor, which, as a consequence, translates into a significant reduction of mechanical vibrations, which negatively affect the conditioner’s internal components, degrading its sound.

The front panel of the conditioner is made of a thick slab of aircraft aluminum, the surface of which, after precise milling, is glazed and then anodized in two color options – black or silver.

In the central part of the panel a True-RMS voltmeter window is built in, along with a pane of scratch-resistant 9H ceramic glass. The voltmeter is equipped with an LED display indicating the precise value of the input voltage. The voltmeter has an isolated input and is immune 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, in white as standard, has an option to fade out. Nine other colors are available upon request.

POWERMASTER 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. The input jack is the company’s C19 connector with rhodium-plated contacts.

The conditioner is also equipped with a system indicating that 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 lack of grounding.

The POWERMASTER also has a ground socket for connecting devices that require ground (such as turntables).

TECHNOLOGY

The POWERMASTER conditioner’s design 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.

All internal components rest on an anti-vibration platform made of non-magnetic materials. It mechanically isolates the electrical circuits, providing excellent reduction of vibrations coming from outside. The 25th Anniversary version uses a copper platform for even better equipotentialization and isolation.

The innovative two-stage power distribution system is based on massive distribution rails made of silver-plated OFHC C10100 oxygen-free copper bars with 99.997% purity. The first stage, with a cross-section of 90 QMM (225 QMM in the Anniversary version), allows for lossless and even voltage distribution to the individual filter branches. The second stage supplies current directly to each quart of output sockets. The company’s 4 QMM (6 QMM in the Anniversary version) silver-plated OFC copper cables with Teflon insulation 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. All connections between cabling and PCB circuits are realized with internal screw terminals with an extreme continuous load capacity of up to 200A. They not only ensure perfect pressure of the connector to the terminal with a torque of up to 2.5Nm, but also extremely low contact resistance ($\sim 100\ \mu\text{Ohm}$).

Anti-interference capacitors manufactured to GigaWatt’s strict specifications are responsible for essential noise filtering. Surge protection of the conditioner is provided by high-end components with increased absorption and aging resistance. A two-pole hydraulic-magnetic circuit breaker custom manufactured to GigaWatt specifications was used as overload protection. This component acts as a circuit to control the value of current flowing through the internal circuits and as the main breaker of the conditioner.

Lossless current transmission is ensured by printed circuits with extremely wide conductive paths made of silver-plated copper with an extreme thickness of 4OZ. Interference suppression is provided by RLC-type filtering blocks, built using, among other things, the company’s Audio Grade filter capacitors and filters based on cores with significantly lower power losses, enabling a significant increase in the value of current flowing through the filter.

A standard feature of the POWERMASTER conditioner is the DC Offset Blocker – a circuit that eliminates the unwanted DC component of the electrical grid. It is based on a proprietary semiconductor module with a continuous load capacity of 100A. It allows to effectively eliminate this phenomenon, without causing compression or any other negative effect on the sound.

The design of the conditioner’s internal components allows it to handle an instantaneous load of 300A! To ensure the highest possible impulse response, the POWERMASTER is equipped with a dual buffering circuit with Audio Grade compensation batteries of our own design. The circuit corrects the power factor and also increases the current capacity of the conditioner allowing almost unlimited impulse capabilities, unparalleled by other similar passive conditioners and unattainable by active conditioners. The impulse capabilities of a POWERMASTER conditioner exceed even the current values of a pure power line.

Great price and Quality
Color: Khaki, Number of Items: 1
Best money ever spent on an office chair. At the time of purchase, it was less than half the price of local retail stores. Once we received it and put it together, it was top notch. Better than expected. Now time will tell how long it stays that way. Very comfortable, strong material, and easy to adjust.

Comfortable Even After Long Hours
Color: Black, Number of Items: 1
I purchased this chair for my husband’s home office, and it has been a great choice. The height and angle can be adjusted very easily, making it comfortable to customize. Assembly was also simple and straightforward. The size is just right, and it remains comfortable even after sitting for long periods of time without causing fatigue. Overall, the quality exceeded my expectations for the price. If it ever breaks, I would definitely purchase the same one again.

Not an average-to-large person's chair by any means.
Color: Brown, Number of Items: 1
PROS: Comfortable seat cushion Feels sturdy and manufactured well Swivels and rolls effortlessly Height adjustment Not terribly heavy Easy assembly CONS: Reclining feature is not great Back cushion forces a very upright sitting posture Pleather material will deteriorate within a couple years It's overpriced for what it is, even at $100. SUMMARY: I'm a little guy. 5'7 and 145 lbs. This chair feels like it was scaled for me and my little frame. Now, while that's perfect for me, nearly everyone else I know or have ever known, are at least twice my size. And I can't imagine them finding the overall size of this thing to be enough chair for them. Maybe I'm way off base here, but I've sat in regular sized office chairs and while they'd swallow me, they're essentially perfect sized for most other people. Feels good to sit in, nothing amazing but it's comfortable enough. Remember, it's made with pleather. Every day use for long periods of time will wear the material out within two or three years. Won't effect it's performance but it will be ugly with cracks and wear/tear far quicker than real leather, of course. It looks very nice right out the box though. Not too heavy either. The reclining feature is a bummer, it's like you really have to force it to lean back, like it's fighting against your doing so. Which if your trying to lean back, you know putting a bunch of effort into your legs is the opposite of what you're trying to achieve - which is relax without tension in any part of your body. It's basically useless for my needs, anyway. The price, even at a measly $100 for an "executive office chair" does not reflect the hiccups with this thing because it's not a one size fits all kind of chair. Anyone over 180 lbs and 5'10 will surely find it to be a bit snug and the back cushion to sit a bit short. The back forces you to sit very upright. Something that will take getting used to, especially since I can't recline. This chair is kinda "meh" to be completely honest. I'll spend at least twice as much next time and get five times the quality. Look, it'll do the job for a while but there really isn't anything very impressive about it besides what it visually looks like. I've no idea how so many people rated this thing with so many glowing reviews. There's not a lot to boast about with a cheap $100 pleather chair that's undersized for most people. I really don't get it. I'd only recommend this at $65-$70. No way this is worth the $100 Amazon is currently pricing it at. Spend just a little a bit more, you'll notice a huge jump in quality over this.

Just Great!
Color: Beige, Number of Items: 1
Comfortable. Wheels roll very well. Great padding. Seems durable. Assembly is the standard with such chairs, takes about 15 minuttes. Do not know how long the PL? leather fabric will last? Probably wear in a couple of years. But for the price, this is perfect. UPDATE: After 2 1/2 months, seat feels flat and very uncomfortable.
