look at the following preamps:
M12(API clone) and M73(Neve clone)
ReviveAudio.com
Also the following Mic's
Advanced Audio Microphones - Professional microphones at affordable prices. We provide studio quality mics for the home and pro recording industry.
You are missing any Sub bass mics...a reverse speaker. and dearly in need of quality large dynamics: RE-20, 421, 441, 431, Hiel PR40, or even the new KSM8
And I would look at owning a single Coles 4038. Since the exchange rate for the pound is currently favorable, good time to buy Coles.
A used Sony C38B is a very useful mic going for under 1K on ebay.
Line Audio CM3's are a HUGE step up from the C1000s and cost under $150 each
e906 is a useful typical dynamic mic for about $200
and if you want to get into Analog summing
Summing Mixer Neumann v475 Vintage Maker - Vintage Design djpaulmusic paul taylor
The C1000S and AT37 are the worst mic's I have ever used...just hate them.
