I bought the stereo box on the day of release; very impressive! And I've now just got the mono box; extremely impressive!! The reproduction covers and inner sleeves are wonderful, and the sound quality is astonishing! I've never heard PPM sounding so raw, and 'live' (the stereo spread spoils it for me) as on this mono set; even my original vinyl doesn't sound this good, and I have a quality turntable!
Pepper is magnificent (of course), and the mono White Album is fantastic (I've only ever heard the stereo - could never afford the mono vinyl!).
Steve.
