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.
