I've seen this topic before on Audioasylum - lots of people gave their inputs but a few of us were in agreement. I'll see if I can dig up that thread on Audioasylum for you.
meanwhile, it is my opinion that the best sounding Bob Marley LPs are the ORIGINALS i.e. non re-issued versions. I have 3 originals & 1 re-issue (Burnin'). I forget which label the re-issue is on. The originals are on Island records & they are recorded in Jamaica. The sonics are really, really nice on these originals. Unfortunately, they are very hard to get too!! FWIW, YMMV.
