You're not keeping your records and stylus clean.
Only just a few of my ~4000 LPs haven't yielded up all their surface noise to diligent and sensible use of modern cleaning systems.
When doing blind tests, first do a playthrough of chosen material to check there is no remaining noise.
But even then it's difficult to run a blind test that will satisfy everyone. You choose a recording that was released on LP and CD at around the same time. But the LP guys will say 'oh but that was badly cut' or 'it was cut a little too hot' and the CD guys will say 'the LP was re-mixed slightly differently. Even when they weren't.
