Sonos Amp (gen 1) brown noise when connecting to Beloab 8000

[Olof Neiglick]

Hello, I have a 10+ year old Sonos Connect Generation 1 connected to a pair of Beolab 8000 which have 20+ years history still working well.  Now I do have a problem that when the Sonos is powerd off (sleep mode), both speakers are intermittently switching on/off (green / red LED changing) and a faint humming noise can be heard.  I have tried to change the cables (from simple RCA to double-insulated) and recently put a electronic filter between the Sonos Connect and the speaker cables.  The latter was even worse, i.e. the brown humming noise was louder and the green light always switched on, even though the Sonos was in sleep mode.  Anyone with similar problem that can share workaround please ?
