Not all records are well engineered, cut and pressed.
Fresh Cream is simply awful. My copy bought on the day of release is very badly distorted right across the frequency spectrum. Pity, as it's great music.
I never was a Hendrix fan and don't have any of his recordings. But I recollect when listening in period the sound was nastily distorted.
If you want well recorded rock music get some early Stones originals, recorded by Decca in the mid-60s when Decca and EMI still cared about SQ. No problems there.
