WHAT IS THE POINT?

Do you love music and want to enjoy it to the fullest every day? Your audio system will only play as well as its weakest part - and this is often an underestimated power supply.

It doesn't appear only pure voltage in the power distribution systems of your homes, but also a large „pollution“, the so-called „harmonic noise“. It´s caused by large factories, powerful engines that are powered from the power network, as well as „transmitting networks“ - FM radio, 3G, 4G and 5G mobile networks, home Wi-Fi, but also by communication between Bluetooth devices. This harmonic noise can definitely degrade the resulting sound. With the increasingly intense presence of these technologies in our surrounding, their impact will certainly only increase. Therefore it´s necessary to filter out these unwanted frequencies accumulated in the power distribution lines before they can enter your audio system and thus distort its sound - because the reproduced music is actually nothing more than an electronically processed electric current, which is subsequently converted into the movement of the speakers, and therefore, if the supply current is distorted, the output must necessarily be distorted as well. The higher the quality of the assembly, the higher its resolution, the more obvious this problem is and the greater benefits our products offer to you.

We use a globally unique know-how and our filter devices operate with much higher efficiency than any of the others with whom we have ever encountered. The proof of this fact for us is a number of satisfied users, expert reviews with excellent recommendations, contributions to discussion forums, etc.

What to expect after connecting our power filter?
Your music will fill the listening space, will come out of the speakers, will have a wider right-left and front-rear space, as well as clearly improve the separation of individual instruments and increase the perceived resolution due to the absence of distortion and background noise.
We build our filters to guarantee zero compression in dynamic range - your assembly will finally be able to sound in full.

Our story

First of all, we´re ordinary guys from Moravia, who fell in love with music and who have had exceptional relation to technology from our childhoods. Music and technology have accompanied us all our lives and especially during our adolescence.The combination of music and its reproduction has influenced us to an unprecedented extent.Our passion aroseat high school and culminated in the final work of a practical exam - by assembling a DUAL MONO amplifier (Pavel), which is still works, although more than 20 years have passed since then, and a preamplifier (Petr) with operational amplifiers from discrete components (very visionary at that time), which also works today.Thanks to this hobby, we also provided to create a custom-made disco room sound system and an extreme sound car system, at the time so popular.

After graduating from college, we began our careers, one as a developer for aerospace and military technology and the second one as a manager in the B2B segment.

Hi-Fi was still a big hobby for us and we bought one component after another as the range of amplifiers, speakers and accessories grew. So it was not a problem for us to get top components. The problem was more financial, because we started our families, solved housing and other private issues.

Another story was when we came to a solution to the issue of filtration.Due to the fact that Pavel works in the field of development of military, transport and aviation technology where great emphasis is placed on direct and environmental interference. We had a clear idea of what the filter should look like and what the internal design should be.Although we did our best, we found out that none of the manufacturers offer a comprehensive solution. Each of solution promised an interesting look at one part of the product, but always solved only part of the problem and did not solve any other possible spreading of disturbing voltage, which can degrade the resulting effect to some extent. And who would like to invest a lot of money in the component which doesn´t meet all required expectations?

That was the moment when Harmonic Hammer was about to be born. Our goal was to develop a device that filters all types of interference, offers strong dynamics and will be one of the best designs on the market.

And our family business began to be born slowly in 2016. Three years later, the product was introduced in its final form. Originally, it was supposed to be a solution for us, but friends and people from the HIGH-END community persuaded us to make it the ultimate product that true music lovers can indulge in and take their listening experience to a new dimension.

We care that our products have our own KNOW-HOW. We do not compose filters from individual blocks because these are used for industrial interference. Therefore, we offer our own solution, which meets the highest criteria and includes exclusivity. Whether it is the first ONE-BOARD Solution, when the product does not have a cable in the power path (imaginary antenna), the use of special components that have not yet been used in the field of Hi-Fi filters until the transformer with galvanic separation, which acts as a storage tank. energy, not embedded impedance. All this, together with the unique design and processing with a high proportion of manual labour, is the added values of our GMG POWER filters.
