I have bass cone movements every 30 seconds lasting for a few seconds. It is not really subsonic, but I think related to this topic anyway.
It is constant and audible with or without music playing but it only happens on the phono stage, not on the other inputs.
I have a Lyra Skala connected to a Lyra Erodion stepup and then an Audio Note M5 Phono.
The earthing is connected from the cartridge to the stepup and then continues to the AN M5 Phono.
The preamp sounds wonderful, but when the cone movements occur, it blends with the music resulting in clearly audible distorsion.
Do you have any idea what it may be or what I can do?
