Back into vinyl, occasionally shocked and impressed and occasionally
feel like a nitwit for geting back in, expecially when buying used albums.

Just got my favorite. Its "Motherlode", Loggins and Messina. The record was purchased used so wtf. Anyway, there is a low amplitude rumble noticealble at higher volumes. Its like some kind of groove noise but I wonder. I also noticed it to some degree on some recently purchased classical albums from around 1974 which may have never been played before. I believe the cartridge is properly alligned, the weight is correct, the tonearm is essentially parallel to the record and the cartridge appears to be perpendicular to the record surface. Think this is set-up/cartridge noise or deep record noise from 35 year old products? Thanks and cheers, dk
