Precise execution

The RD PWR-CU power cable is unique in its construction; it combines the advantages of copper and silver fiber for ideal conductivity and stability in frequency. Quality connectors with gold-plated contacts serve as protection against oxidation and provide ideal contact in the socket. The device part of the cable is constructed with high pressure on the contacts for perfect current transfer to the appliance. In order to increase immunity against external electromagnetic fields, the shielding on the fork side is connected to the PEN terminal. The cable is fitted in cotton braiding that is also part of the internal dielectric due to cotton's excellent isolating properties. The four-layer insulation, very good flexibility and minimal internal impedance all ensure a reliable and powerful connection of your audio components to the power supply. The design then blends in with the rest of the audio chain.



RD EMI Neutralizer Power Filter
€ 7 486

Is a complex power filter with integrated surge protection. The filter increases the distance of background noise from useful signal, making the sound more crystal-like, with more details. Filter omnipresent high frequency interference effectively and supply your sensitive audio components with clear power!

RD Power Filter
€ 1 210

Is a unique power filter combined with surge protection. This article from RDacoustic’s workshop effectively protects your audio appliances and other devices against overvoltage (lightning strikes and other causes) and at the same time cleans the power supply from unwanted electromagnetic interference, resulting in an improved sound quality of your audio devices.

Protect your devices the pure way.

Why OFC copper?

Oxygen-free copper is characterised by high electrical and thermal conductivity. OFC is made using electrolytic refining in order to reduce the oxygen level down to 0.001 % or less. The resulting material has excellent conductivity and very low electrical resistance.

The Skin Effect Exists
19. 1. 2018

Is the term “skin effect” often arising in the audiophile world only a “voodoo fallacy”, or does this phenomenon, as described by J. C. Maxwell in 1892, really influence music reproduction?

Background Noise in Audio
1. 8. 2020


Our new listening studio is not for listening experiences only. It provides us with a good enough space to carry out different experiments, measurements and tests. This article deals with background noise measurements of an audio system, in the hearable spectrum. Using a microphone, we measure the noise coming directly from the speaker. We are going to compare a real noise of an amplifier, once powered directly from the power grid, once using RD EMI Neutralizer power filter.

Measuring Power Grid Interference in Practice
23. 11. 2019

Would you like to know what interference occurs in the power grid? Why deal with filtration? To illustrate the issue, I made measurements at four different places. For comparison, I used a common EURO cable and RD Power Filter.
