Hey all, I've been wanting to upgrade my recording set-up for a while due to the numerous bugs and sound quality issues I have to deal with in my current set-up. I have a small sound-proof studio to record in so that improves things greatly, but I'd like some better equipment.

Right now I have:
Mic: MXL 3000
USB interface device: M-audio Fast Track Pro
Software: Sony Acid

Can someone tell me what might be a good "step up" from this?

Thanks!
