Joris,
If you are still following this tread I would say that the SP C3 has been one of the purchases I have been most pleased with for my home studio.
My signal chain (for now) is very simple. I run the C3 directly into my Aardvark Q10 into Sonar.
Here is a link to some tracks where you can hear it on vocals and acoustic guitar:

This week I got my Meek Preamp, FMR RNP and a couple RNC's. Next weekend I will be doing my first tracking (scratch tracking) with those units.
If you are interested I would be happy to share the results with you.
Bear in mind that everything thus far is scratch used for composition, but hopefully gives you some indication of the quality of the C3.
I also have a couple B1's that I have yet to find a great application for. On vocals they sound nice, but just not as nice as the C3. Since they are fairly well matched I have had some luck with using one of them along with the C3 in omni for M|S recording of acoustic guitar.
I hope that this information is of some use.
Jim
