If replies to the question of sound quality on Specials CDs continue much longer, maybe we should create a thread just for this discussion. For the first album (The Specials), I own the US 1989, UK 1989, and 2015 versions, and have heard the 2002. What I consider to be the "best" of these three options is the 1989, and it's dynamic range that gives it the edge. I haven't done a close comparison between the US 1989 and the UK 1989, but it seems they're the same mastering, except that the US includes "Gangsters" and the UK features the longer version of "Too Much Too Young." Regarding the newer masterings, the 2015 isn't much louder than the 2002, if I'm remembering correctly. But the 2002 sounded juiced to me, and by that I mean artificially inflated with EQ. So in evaluation of all the CDs mentioned above, the 2015 comes in second. It's clear, with EQ that sounds accurate, and obviously benefits from modern analog-t0-digital conversion technology – but unfortunately it is slightly limited / compressed. Not egregiously so – the limiting there is comparable to what was done to the 2009 Beatles CD remasters. I have not heard the SHM-CD mentioned by Cereal Killer. If someone can say it's the definitive version of The Specials, I might pick it up. I can't speak to the differences between compilations that feature all the singles, but for what it's worth, I've always been happy with The Singles Collection from 1991.
