If sound quality is paramount for you, in classical LP's I have generally found Phillips to have excellent quality and some good recording artists as well. DG is touch and go. EMI, London, Decca also have excellent recording practices and the surfaces of all of these were usually quite good (when new). Angel & RCA have some good music but a lot had pressing problems. RCA Living Stereo however could be just outstanding, as could Mercury Living Presence. You can also find great LP's by Telarc. For CD's you usually get good sound from London/Decca, EMI, Chandos, Telarc, BIS, Hyperion, Harmunia Mundi, Delos, Dorian, Denon, but watch out on DG these have similar problems to a lot of their LP's. CBS (Sony) and RCA as well. On the major labels the music recorded in the last 10 years usually sounds very respectible. Enjoy.......
