Which clockport soundcard shall I get?

[rvo_nl]

Hi, Im looking for 'one more' upgrade to my system, which is a sound card that I can connect to the clock port. Afaik, I can choose from 4 options:
 
Delfina
Melody
Prelude
Prisma (not yet released)

My requirements are:

- should fit in my system (I have indivision, bvision)
- should work under OS3.9 and 4.1 Classic
- should support AHI

can I already rule something out? Any important differences I should be aware of?

Keep in mind I just want a bit better audio playback, mp3 decoding doesnt interest me much (I have ppc)

thanks both, this is helping! now I hope both melody and prelude are easy to fit in my tower. can someone comment on that? keeping in mind the expansions already in there.
