Any of the HMV (EMI) recordings of the London Symphony Orchestra with Andre Previn from the 1970s are worth listening to. The Interpretations are top notch and the sound is glorious. One of the best recording Engineers of all time was Walter Clegg, husband of Elizabeth Schwartzkopf, who made many recordings for HMV - everyone a star.
Any recording by Weller on Decca is also good value.
Arthur Salvatore of High End Audio gives a comprehensive list of the audiophile classical recordings on his site. All vinyl of course but many of them have been transcribed to CD, Note these are the best recorded/sounding versions which of course does not mean they are the best interpretations.
