I have Tommy, Who's Next and Quadrophenia. Tommy is the only one that is defect free. All the way through Baba is this right channel scratch noise that is irritating to the point that the disc is no longer playable. Side two is defect free, thus this is a pressing defect. Side two of Quadrophenia has several similar defects; the other three sides are defect free, but side two happens to be my favorite complete side of that album. My MCA reissue pressing of Who's Next is somewhat better but is not defect free; it has several pops and ticks in places that make them clearly audible and distracting. My old Who's Next on Decca is still my best version of this classic rock recording. For shame to the nu vinyl wannabees. I still think they are trying to press too quickly, need to leave the biscuit in the press a little longer, and need to use higher quality vinyl.
