Lehmann Audio Black Cube crackling in the acoustics

Hi, I am happy to use lehmann black cube statement + original PWX. I recently discovered an unpleasant problem. My audio system consists of: technics sl-1500c MC cartridge AT33EV, and amp Musical Fidelity M6si. I can hear the fans in the WC and bathroom turning on through the speakers. I also hear the refrigerator motor turning on. However, I don’t hear the air conditioning motor or hood in the kitchen turning on, and that’s good. The power wiring in the house is new. Please tell me this could be a problem with my lehmann black cube.  Alex

Is this a new problem and things previously worked in that house? If so, not household wiring. If present for phono only, but not other sources, it comes down to table, cartridge, Cube. If other sources, amp should be included in suspects.

If present since you moved in (you say wiring is new): Is the hi-fi on the same household circuit as the fans? If so, consider a separate circuit for hi-fi.

Yes, the system is connected to the same home network, I just used a MM cartridge before. I upgraded and this problem appeared . But the air conditioner and kitchen hood cannot be heard to start

Ah, I meant the power circuit, not the network. If there is a noise when the fans in the bathroom turn on it might be transmitted via the power supply. Some people go as far as to use a separate circuit from the panel to the sockets supplying the audio gear to avoid that.
