Vinyl reissues quality

I have purchased 10-12 rock/pop/female vocal vinyl reissues lately and the surface noise on about 30% of them is loud enough to be distracting. The surface noise isn't the occassional click and pop but ranges from a constant crackling to constant low roar almost like tape hiss. Cleaning helps some but does not solve the problem. I have LP's from my college days that are 30 years old and are quieter than the brand new 180 gram virgin vinyl reissues. Am I unlucky or are others experiencing the same?
