Switching power supplies, high-frequency oscillators, and constant data communication generate a wide spectrum of high-frequency “junk” that is distributed via the power grid. This interference is often far beyond what conventional measuring devices can detect, but it can significantly affect sensitive audio equipment.
Digital and analog circuits are equally sensitive to such interference. Sonically, this often manifests as harshness: high frequencies sound harsher, voices lose their naturalness, and prolonged listening becomes more tiring. Power conditioners are a proven method for counteracting these effects – they filter RF interference and stabilize the power supply. However, even here, the following applies: as long as the source of the interference is active on the same network, some residual interference remains. The most effective approach is complete isolation.
A power storage system designed exclusively for audiophile applications and supplying the system autonomously is completely unaffected by Wi-Fi, smartphones, and smart home technology. A system like the Stromtank S-4000 ProPower MKII delivers energy without wireless interference – resulting in a noticeably more relaxed sound
