Hi, I've been researching on microphone preamps quite a bit, and wondering whether upgrading to dedicated outboard preamps would really help the sound quality. It can be quite a heavy investment, so I'd like to be really sure before taking the plunge. I have seen people swear by certain designer preamps with magical adjectives. I have also heard some people say the difference between a budget-but-properly-constructed preamp (e.g. those included on the typical audio interfaces) and an expensive one is really minimal and almost insignificant. My question to all you professionals and recording engineers is this: would a designer brand preamp really benefit the recorded quality? Of course, I am comparing it with the standard budget built-in preamps that comes with, say, a Presonus FP10. Please help!
