Have had some reissue pressings which sound dull and lifeless compared to 70s originals and ocassionally vice versa
only have one half speed master in the collection which is monkeyhouse friday and the quality is outstanding but then also some bowie reissues which sound decidely average
its quite nice when you pick up an old original 70s or 80s disc and the production and mastering are so good it still sound fantastic today albeit it with a few extra pops and crackles
then again there are some things also which both labels and/or artists have steadfastly resisted re-releasing, so if you want your copy then vinyl is the only choice
re the OP comments, the same near here with the big hmv store at bluewater shopping centre, extremley well stocked but extremley high prices too, but there are plenty of local shops fortunately covering both used and new vinyl at much better prices and better overall shopping experience imho
