The most difficult part of the cable development was the power cord. Even if the task of the power cord seems banal at first glance, you can hear clear differences between different power cords.
Only a thought experiment put me on the right track: The amplifier can be seen as a controller that gets all frequencies present in the music signal as current from the power supply to send the current in the form of the music signal to the speakers.
That is, the power supply must deliver the energy to the power amplifier evenly over the entire frequency range.
The same applies to the source, e.g. CD player. The structure is the same; the power supply delivers the energy, the amplifier stage in the CD player output sends, all frequencies that the music signal specifies, as energy to the amplifier.
And the power supplies of the CD player, as well as the amplifier, hang with their power cables on the power strip. Therefore, within the power strip, special care must be taken to ensure that the power supplies of all devices are supplied synchronously with the music signal.
This is also why it is so important that all devices are supplied with the correct phase from the power strip. When this is not the case, listeners report disastrous musical effects.
That’s why I matched the mains cable to the RCA and LS cable in terms of broadband, i.e. both the „skin effect“ and the „proximity effect“ were taken into account.
