I currently have a Studio Projects C1 microphone and am planning on purchasing a firewire interface.
To get the best value for money, would I get the best sound from buying a firebox and better mic, or from using the C1 and buying a Mackie Onyx 400F?
Getting a good vocal sound is my main priority.
The Firebox and Onyx have different numbers of analog ins (4 vs. 8 respectively). If you get the Firebox, will you end up needing more channels in the future? If you're doing mostly home demo & singer/songwriter stuff, is 8 channels going to more than you need?
I have
a Mackie Onyx 1220 and the pres are really good, though I usually end up using outboard ones instead (UA m610 or CL 7602) for vocals. The a/d converters (another important component that will influence the final sound) on the Mackie are reported to be very good for the price as well, but beware if buying the Mackie 400f-- the whole Mackie firewire line is known to have incompatibility problems with some computer processors and/or chip sets. If you're strongly considering one, I'd check the Mackie Forums to see if your computer model is addressed there.
If there are no compatibility issues, and if you're not going to need more than one or two channels at a time, Mackie makes a new firewire interface called the Satellite that has two Onyx pres, though it has received some mixed reviews.
Mics, pres and other analog outboard gear is generally regarded as a good place to invest (digital stuff, inevitably is eventually rendered obsolete), so depending on what kind of chain (i.e. pre, interface, etc.) you're using now, you'll probably experience an increase in quality in either case.
