The manual of the VPI HW-19 MKIII recommends that "the dust cover be down when playing records. Under most circumstances this will result in cleaner sound since the cover acts as a 'shield' against acoustic feedback." And of course keep the record and stylus clean.
Ok guys
My question is this, nothing major, more of a curiosity. When playing an album does it make a difference if you leave the dust cover up or down? Probably stupid question but hey there are lots of opinions out there
