Using m-audio fast track, it's ok for basic recording, but for
getting a top notch sound, i dont think it's good enough.

Considering you can pay over 1500 and more for a quality pre, im not sure if the lower end stuff is worth buying.

Aside from using a quality mic, quality signal chain and good sound proofing, not to mention quality vocals and positiing, a great pre is the real difference maker.

But everybody's opinion varies, that's why im asking.
