The Odeon Japan issue LP's are the best for pre Wish You Were Here LP's. Then CBS/Sony Japanese for WYWH through The Final Cut. Wish You were here, The Wall, and A Collection of Great Dance Songs are available in Half Speed Master series. For Dark Side of the Moon there are several Audiophile pressings. MFSL UHQR, MFSL standard pressing, EMI Centential pressing, EMI 30th anniversary pressing, Japanese Pro-Use pressing. The BEST sounding Pink Floyd solo LP is Roger Water's Amused to Death pressed in Holland. It's a 2xLP direct metal master. Not many were pressed and currently sealed copies can set you back $300 or more. I'm glad I bought mine new when it first came out.
