Dear @chenglo1 : If that happens only with LP and not CD then you have a problem with your analog set up where exist a low frequency feedback.
It can comes from any where: cartridge, tonearm, cartridge/tonearm combination, TT, TT plattform, LPs and even the phono stage. It’s not easy to say, you have to check link by ling of your analog rig using the LPs with more " problems ".
Regards and enjoy the MUSIC NOT DISTORTIONS,
