No matter what you do, the PC games of that era will always sound worse than their Amiga counterparts, at least until a certain year where they managed to bring PC soundcard up to par with the Amiga chip. If you really care for a game's sound, your best bet is to download the Amiga version, if available.
A good page with Amiga games and their soundtracks is:

Hmm, this is already the third thread today that I posted about Amiga. I hereby declare this day the official Mad-E-Fact Nostalgia Day!
