Power supply

Where does fine sound begin? Where does it end? These questions ring constantly in our ears. The truth is, various factors have a major impact on the sound quality produced by audio systems, and one of these factors is power supply. It is subject to fluctuations that vary depending on the location of your home (in a city or a rural environment). If we look at things from a purely physics perspective, the music produced by a loudspeaker is ultimately nothing more than domestic current converted into sound. This statement sounds almost too banal compared to the hi-fi jargon we are all accustomed to. Unfortunately, all too often we ignore where the sound actually comes from and the importance of having a stable power supply. A “clean” current is the raw material of fine sound, and our AC-4500 Power Station makes sure that this is what you get. The AC-4500 Power Station is available in several versions – from a basic model with one filter for all six sockets through to the top model that comes equipped with six separate filters, one for each socket. The models differ not only in the number of filters they are equipped with, but also in the combination of filter types they provide – type I (for analog devices) and type II (for digital devices). The AC-4500 Power Station was developed completely in-house, and each unit is manufactured in the company’s own facility. Units subsequently undergoes rigorous testing with documentation of the results. Because safety is paramount for this type of unit, we have also arranged for an accredited laboratory to verify CE/CB conformity. The Power Station’s sensitive technology is protected by a robust metal housing made of 2 mm-thick galvanized sheet steel. It has an elegant front panel made of brushed aluminum. The interior of the housing is designed so that the socket groups are shielded from one another, and any interference stemming from the connected devices is unable to propagate.

The Referenz AC-3502 Power Station reliably suppresses undesirable interference from the power grid. At the core of the power distributor is a highly efficient parallel filter, finely tuned to audiophile requirements, which effectively dissipates annoying interference both from the mains power and from the connected devices themselves without restricting the energy supply. The star-shaped distribution also ensures a homogeneous supply to all connected components. The Referenz AC-3502 Power Station is a central pillar in achieving a sound that is both refined and powerful. The technology sits in a solid metal housing with a brushed black anodized aluminum front. Six high-quality sockets are available at the rear. Thanks to the central high-current mains connection socket (IEC C20), the power cable can be easily replaced if necessary, with a longer cable for example. Integrated surge protection safeguards the connected devices from everyday voltage peaks, and the sockets can be conveniently switched on and off using the "Power" button on the front panel

A hi-fi system basically reproduces nothing other than modulated household electricity. It is therefore crucial that it reaches the device constantly and without interference. Mains cables and the associated plugs play a central role here. Extreme current peaks in particular, which are caused by the conversion of alternating current into direct current, can lead to loss of sound if the contact resistance is high. Our high-quality mains plugs are specially designed to meet these challenges and raise the sound quality of your hi-fi system to a reference level. Available in different versions, our power plugs offer the perfect solution for those audiophiles who want to get the best out of their system.

Excellent sound starts with the power supply – and this is exactly where the AC-3200 power strip with integrated DC blocker comes in. It filters disturbing direct current components (DC offset) from the power grid, ensuring a symmetrical voltage supply. Ring core transformers benefit especially from this: humming noises are effectively prevented, efficiency increases, and distortion decreases. The DC blocker technology also protects the transformers from magnetic saturation – a condition that not only causes noise but also costs power and can impair sound quality. The AC-3200 was fully developed in-house – from the initial concept through prototypes to the finished product. It is manufactured in our own workshop. Inside, massive copper busbars and high-quality sockets ensure stable conductivity and reliable power distribution. The brushed aluminum housing protects the technology and represents durable quality. An integrated surge protector provides additional safety for your hi-fi components. Each AC-3200 is individually tested – with CE-compliant high-current protective conductor testing and high-voltage insulation measurement. This ensures that every power strip meets the highest technical standards – for reliable operation and long-lasting sound quality. Note on the variants: The AC-3200 DC blocker is available in three versions: DC-15, DC-30, and DC-45. All three versions are designed for a maximum socket power of 3680 watts. For medium and large high-end systems where more punch and dynamics are required, we recommend the DC-30 or DC-45 variants with two or three times the capacity. This provides the right solution for every setup – from compact systems to powerful hi-fi systems. Click here to discover exciting details

The AC-3200 power strip with filter type I was specially developed for analog hi-fi components – such as amplifiers, preamps, or turntables. At its core is a carefully tuned, series-wired filter network that routes power through high-performance coils. These coils offer targeted high resistance to power line interference and effectively reduce disturbances from switching power supplies, household appliances, or industrial equipment. Especially in modern power grids – increasingly affected by digital devices, EV charging stations, or photovoltaic systems – such a filter can make a crucial difference. Although many hi-fi devices have their own power supplies and protective circuits, not all interferences are fully eliminated. Residual noise can still affect the audio signal and reduce sound quality. With the AC-3200, your analog components receive a noticeably more stable and interference-free power supply – for a quieter soundstage, more precise detail, and overall enhanced musicality. The AC-3200 was developed entirely in-house – from the first concept to full production readiness. It is manufactured in our own workshop. Massive copper busbars, durable sockets, and a protective aluminum housing ensure low-loss power distribution and long-term reliability. An integrated surge protector adds extra safety for your system. Each AC-3200 undergoes CE-compliant individual testing – including high-current protective conductor testing and high-voltage insulation measurement. This ensures that every unit delivers exactly what you expect: clean power for uncompromising musical enjoyment. Click here to discover exciting details
