A hi-fi system basically reproduces nothing other than modulated household electricity. Consequently, it should arrive at devices with as little inhibition as possible. The big challenge for power supply cables is extreme current peaks. These are caused by the connected devices themselves converting alternating current into direct current. Such extreme current peaks cause a whole range of undesirable effects, which is why the power cable is of particular importance. The Referenz AC-2502 mains cable is equipped to deal with this demanding task, and is specially designed for connecting up high-quality hi-fi and high-end audio systems. Its features include 3.3 times the normative minimum conductor cross-section and shielding to protect the sensitive audiophile components in the chain from the interference fields caused by the current peaks. Safety comes first: However much we focus on high-end sound, safety plays a particularly important role in this cable category. That’s why every AC-2502 undergoes an insulation and high-voltage test in addition to the standard function test. The results are documented, and each cable is given an individual serial number.
The mains cables (power cables) play a really special role within the hi-fi system. They need to manage the impulsive power consumption caused by dynamic music passages on integrated amplifiers, power amplifiers or active loudspeakers. In addition, the extreme current peaks, amplified in the devices during conversion from AC to DC voltage, must be passed to the individual hi-fi units without delay or loss. Any "inhibited" current flow leads to high power losses at line and contact resistances, and has a negative effect on the sound of the hi-fi system. For this reason, the AC-1502 was developed with very low transition resistances. In addition, high-density shielding protects the neighboring components from strong magnetic fields and interference caused by the rapidly changing current increases and decreases in the power cable. The result is a hi-fi mains connection cable with an outstanding price/performance ratio that raises your system to a higher sound level in terms of dynamics and reproduction of detail. However much we focus on high-end sound, safety plays a particularly important role in this cable category. For this reason, every AC-1502 mains cable undergoes exhaustive tests. In addition to the functional testing, each cable is subject to an insulation and high-voltage test. The results are documented, and each power cable is given an individual serial number.
The Referenz AC-2502F mains cable guarantees a stable and clean power supply. EMC interference, from sources such as mobile phone and WiFi networks, is constantly increasing. The dense shielding protects the sensitive signals from this type of interference, so retaining the fine detail. The massive conductor cross-section of 3 x 2.5 mm² minimizes resistance and delivers sufficient substance even in dynamic passages.

Electrical installations in buildings are usually carried out professionally, but often as cheaply as possible. This means that the cables from the fuse box usually have to run via several junction boxes and terminal points to reach the sockets. Each terminal point means additional contact resistance and additional loads from other consumers in the room, leading to losses and interference in the power supply. Ideally, a separate line should be laid from the fuse box to the socket of the hi-fi system. The Referenz AC-2503M is particularly suitable for this application. In addition to its large conductor cross-section of 3 x 2.5 mm², it has a shield that protects the components from electromagnetic interference along the entire length from the fuse box. Application: For a separate power supply from the fuse box to the socket of the hi-fi system. Optimum power supply: The direct connection from the fuse box to the system avoids contact resistances and any interference caused by terminal points etc. Stable performance: A full conductor cross-section of 3 x 2.5 mm² minimizes resistance and provides sufficient substance even in dynamic passages. Shielding: Tight foil shielding protects the sensitive signals from interference, so preserving the fine details. WARNING: The cable must be installed by a professional!

Audiophile Power Supply
Optimal hi-fi power supply: The basis for perfect sound from your hi-fi system
Why is the power supply important? In many households, the power from the wall outlet is often not as “clean” as is required for highly sensitive hi-fi equipment. Voltage fluctuations, electromagnetic interference, and other sources of interference can impair the sound quality of your hi-fi system. An optimized power supply ensures that your amplifier, CD player, streamer, or speakers can deliver maximum performance and precision. This brings you closer to the music than ever before
Power cables: The connection between sound and power
High-quality power cables are an often underestimated component of the power supply. While many people believe that the cable supplied with the device is sufficient, experience shows that specially designed power cables can significantly improve sound quality. They reduce interference, ensure a more stable power flow, and create the basis for a neutral and dynamic sound image. Especially with high-end systems, choosing the right power cable is a crucial step toward perfect listening pleasure.
The importance of power cables goes beyond mere connectivity. The quality of materials used, such as high-purity copper conductors, and precision manufacturing techniques can greatly affect the cable’s resistance, capacitance, and inductance. These electrical properties influence the amount of electrical noise and ripple that reaches your audio equipment. A low-noise, low-ripple power cable helps maintain a stable output voltage, which is critical for sensitive analog and digital audio components.
In addition, shielding and insulation play a vital role in preventing electromagnetic interference (EMI) and radio frequency interference (RFI) from corrupting the power signal. High-quality power cables often incorporate multiple layers of shielding and use advanced insulation materials to minimize these effects. This results in a cleaner, more refined power supply that supports the amplifier and other devices in delivering precise and distortion-free sound reproduction.
Moreover, the mechanical design of power cables can affect vibration and microphonic effects that may subtly influence the audio signal. Cables designed with vibration-damping features and robust connectors ensure a secure and stable connection, which can further enhance the overall sound quality.
Investing in better power supplies, including high-quality power cables, is a critical step for audiophiles aiming to achieve the best possible sound experience.
Power strips: More than just distributors
A high-quality power strip is an indispensable component of any optimized power supply. Unlike conventional power strips, which often amplify interference or signal loss, special hi-fi power strips are designed to keep the power flow clean and stable. Many models also feature additional filters that eliminate electromagnetic and high-frequency interference. This ensures that your hi-fi system is supplied with a steady, interference-free power supply at all times – ideal for making the sound of your high-end system even clearer and more dynamic.
Beyond basic power distribution, audiophile-grade power strips incorporate advanced design elements to minimize electrical noise and voltage ripple, which are critical factors affecting sound quality. These specialized strips often use high-quality parts, such as precision resistors and capacitors, and sometimes include linear power supply technology or dedicated filtering circuits to further purify the power delivered to your equipment.
Moreover, the layout and construction of these power strips emphasize shielding and grounding to prevent the introduction of noise from other connected devices. This is particularly important in systems where sensitive analog and digital components coexist, as noisy power supplies or switching supplies connected to the same strip can degrade overall performance.
In addition, some high-end power strips offer isolated outlets or separate power channels, allowing audiophiles to connect different components without cross-interference. This design consideration helps maintain the integrity of the power signal and supports optimal amplification and sound reproduction.
A quality power strip is not just about protecting your equipment from surges or providing convenient outlets; it is a foundational element in achieving the purest possible power delivery.
Power filters: protection and sound quality in one
Power filters are the secret weapon of many audiophiles for protecting your hi-fi system from interference from the mains. These devices specifically filter out unwanted voltage spikes, mains noise, or electromagnetic influences that could negatively affect the sound. A clean power supply not only ensures significantly improved playback quality, but also reduces the risk of damage to your high-quality equipment. With a power filter, you can bring peace to your hi-fi power supply network and get the most out of your setup.
Power filters work by employing a combination of passive and active components such as capacitors, inductors, and sometimes specialized semiconductor devices to attenuate high-frequency noise and transient disturbances. This reduces the ripple and electrical noise that otherwise propagate through the power line and can be picked up by sensitive analog and digital audio components. By stabilizing the output voltage and reducing electromagnetic interference (EMI) and radio frequency interference (RFI), power filters help maintain the integrity of the audio signal chain.
Furthermore, advanced power filters may incorporate DC offset suppression, which is particularly important in audio systems where DC contamination in the power line can cause distortion or even damage to amplifiers and other equipment. Some high-end models also feature multiple filtering stages and isolated power channels to prevent cross-contamination between different components connected to the same power source.
From an audiophile perspective, the use of power filters can translate into a noticeably cleaner and more transparent soundstage, improved dynamic range, and enhanced detail retrieval. This is because the reduction of noise creates a quieter background, allowing subtle musical nuances to emerge more clearly. Moreover, power filters contribute to the longevity of your equipment by protecting it from harmful surges and voltage spikes that can degrade internal components over time.
In summary, integrating a high-quality power filter into your hi-fi power supply chain is a critical step for anyone serious about achieving optimal sound quality and equipment reliability. It complements other elements such as linear power supplies, premium power cables, and specialized power strips, collectively ensuring that your audio system receives the purest, most stable power possible.
