I'd be thinking quality portable solutions (rather than a console) and looking to
acoustically treat your studio if you haven't already.
Also, one thing I've
learnt over the years, and have been pretty fortunate with, is to invest in gear which may
still be useful in ten years time, not just 10 months. Upgrading gear after two or three
years is expensive.
The one interface that I think has a lot of potential
right now is the UAD Apollo ( being reviewed in SOS next month) appears to have four good
preamps, onboard UAD card, good conversion, but let's see what the SOS gurus say. It also
has Thunderbolt which looks like it may supersede FireWire. Add to that some boutique
preamps, say DAV BG2, and you have a very powerful solution, which you're not likely to
tire of for some time.
Add to that good monitoring and then you can focus on
spending the rest of your life collecting microphones..........
