I hope this isn't too dumb of a question, but before I go out and spend a bunch on the Presonus or Sebatron, I figured I would ask it. Right now I'm using a Mackie 1604 VLZPro mixer and going into a motu 2408. Mackie says the the VLZPro has great mic pres on each channel. Are those sufficient? Hype? Still need the 8 in mic pre? Thanks!
