Sounds like the people here are bitter about software getting stolen.
Best thread ever!
And to be honest, with the KSM27, pretty much any preamp (that didn't cost 4 dollars and is installed in a consumer soundcard

), you should be able to get passable results with all that gear.
Perhaps post a clip so we can hear what you're talking about? The problem with recording is that it isn't a magical black box that you throw frequencies at on one end, and out the other end comes professional-sounding material, even if the original music was bad.
Not to be harsh (as we all are in this thread, as of this post, due to the fact that it looks like you hosed the software industry with lots of illegal freebies), but you may just not like your own voice. All the processing in the world is only going to make you sound a little better than you do now, and the stuff that makes those improvements takes time to learn and use, and even then its all a bandaid over a gaping gunshot wound.
Advice time!
I suppose you could try a different mic, a different mic pre, but in the end, you should be at least marginally happy with the recording of your own voice, with no processing or effects, and it seems with that mic, and maybe a better interface to the computer, you should be able to pull it off. When I record material, the vocal track usually gets light compression, maybe some reverb if I think it is called for, and that's it. I don't have a great voice, but its passable for what I want to do, so I'm content with it - without using pitch correction, depth enhancers, stereo spacing plugs, echo, reverb, chorus, etc etc
