I sow many rappers (on tv mostly...lol) when recording put they mic upside down... why?

Hello,

I'm setting up a home studio. I want to record rap vocals with the best possible microphone, pre, and sound card within my budget. I will be recording my rap vocals with the help of a sound engineer I am hiring. If you want to hear what my voice sounds like please visit:

I've got around 3000$ to buy new equipment. I want to buy a preamp and a mic. I record rap vocals and sometimes female's singing.

I have a PC with an M-Audio delta 66 soundcard and a Omni i/o. I record into Sonar.

I was thinking:

pre: Avalon 737sp.
mic: Shure Ksm44, or Something from Blue at around 1000$.

what do you guys think?

Would you consider an AT3035 to a RODE NTK a significant upgrade?

It would be mainly be used for hip hop /rap vocals. .

if you don't think so give an opinion to a better one?

all ears.

someone let me know pleaze

I've been looking for some time now at getting a new mic ( I currentley own one mic an AT4033 and haven't had great succsess with it on rap vocals a couple of female singers have had great results though which that mic exsels at that anyway )
