No prob at all Eraze, you can use anything reasonable to record you vocals. See i started upgrading to higher end gear cause i realized the limitations of some of things i was working with, like the Studio Projects C1 is extremely bright and often times brittle on certain types of voices, it was pointed out to me by quite a few dudes in the states. I recorded an artist called Whosane who told me when he got back to the US his producers and peoples kept asking him what mic he used, cause it didn't capture his voice the same way i mean in a good way.
Its also in the Pre-amp and that can change the mic's characteristics. i'm investing in a Rode K2 next month and then moving i gonnaa invest in the Neuman U87 (one of the dopest mics in the industry)
i recently bought the Universal Audio 6176, which an amazing pre for micing and instruments, i also bought the Focusrite Voicemaster pro (platinum), both are beasts.
i had a studio projects pre that i used before on the C1, when i moved over to these Pre amp's, wow just amazing.
Invest in your vocal chain... you Soundcard --> Pre-amp ---> and Mic. trust me, work on that first.
I also use a Quad Processor G5 MAC though

(just braggin!!!)
