The MBP will set you back at least $1500, so here's what I'd do with the other $8500:
First, sell the MBox 2
. You're steppin' up here.
Sounds like you need more than a couple of simultaneous tracks. You can get a Firewire interface with 8 mic pres or even consider the RME Fireface UC
, which is USB with two mic pres and 6 or 8 line ins (can't remember). The UC will set you back about $1300. I don't care much for Protools and like how Cubase integrates with the Steinberg firewire interfaces. You can get two new units (16 mic pres) of MR816x
online for about $1400. Etc., etc., there are many options and you might want some hands on time before you buy.
Get at least one channel strip. I'd recommend the Presonus Eureka
used, which can be had in the $250 to $300 range, or maybe one of the ART tube based units.
Monitors - go out and listen to monitors. For a $10K budget, I'd allocate ~$1500.
At this point, you are down to about $5K remaining. I'd spend $2K on acoustic treatments, $2K on mics and $1K on plugs. If you buy a bundle like that of Soundtoys (between $400 and 500 if I remember right) you'll have the fundamentals covered, then go for something more exotic that catches your fancy.
With $2K to spend on mics, you have some latitude. Get a three or four dynamic mics like the 57 or the i5 that will work well in a range
of applicaions. ~$400 there. Then look at condensors. You can get a used blue Bluebird
for under $200 or new for around $300. I'd want a couple of condensors at least and would look at the AT's, Rode, AKG Perception or maybe one of the imports from China. Consider a ribbon like the Fathead, which I think is around $200. Save a few bucks for stands and cables. you can get very good headphones in the $100 to $150 range but like monitors - GO LISTEN TO THEM. Mics and monitors - the opposite ends of the chain, introduce their own distinctive signature. Make sure you like them before you buy.
