There are two very distinctly different mixes of En-Tact; the original UK issue with the embossed black/silver cover, and a later remix for the US market in a blueish grey cover that became standard ever since. IMHO the original is *a lot* better. The remix smoothed everything out and made it far more generic, the original has such a great vibe/feel to it. This carries over the CD, the original black silver cover issue is the original mix with so,e extended mixes too. Well worth hunting down even if you have original vinyl (either the 2x45 or 1x33).
Edit: Discogs implies the fairly recent 2x45 reissue is actually the later mix, not the original, so go hunting originals!
Tripomatic Fairytales is a great album. I had the CD since it came out and much to my astonishment I found the vinyl in a local £1 bin (a dealer who doesn't know electronica at all) about a decade ago.
