Now THAT'S how to do it - new life breathed into so many classics without ruining them: an excellent effort, and hard to achieve satisfactorily :-) Everyone should download this pack of familiar tunes and appreciate the boost they've been given by listening on modern headphones. The added proper separation and depth makes some songs almost sound like remixes!
I once had a go at remastering a bunch of my favourite Amiga tunes - ouch - 15 years ago, by spewing them through a studio rack of physical analogue processors/FX units. I chose several genius tracks that I always thought might almost "pass" as commercial songs. Sadly though (1) I mastered the results to minidisc (as was the style at the time) thus losing definition and (2) I didn't really know what I was doing, hence pumping over-compression. Here's the best of the experimental bunch:

Memorable Euro business from Tip/Firefox, Phenomena's Enigma demo soundtrack
Anyway, that's how not to do it, but I kept hold of these too all the same :-)
