my 8000‘s do have a slight noise, independent from the volume, not sounding like typical white noise or 50Hz (Europe) ground humming, but like a littl „softer“ random noise.
Nevertheless, as I considered the foam rot which killed already my two 4000‘s some time ago or leaking capacitors; I opened them today to remove it and to maintain the capacitors.
But then I was suprised, the speakers had already the white material, in a stable condition (see pictures showing also the serial and Itrm No).
My question is now, from which serial number on were these applied? As mine is 15680277, which „MK“ do I own, are these even the one with ABL? How old could they be and might require anyway a cap service?
Now I also am unsure whether to maintain the capacitors or simply leave as is.
Is anybody also facing such a noise?
Thanks a lot in advance and have a happy new year!
