bluntforcetrauma - you really must decide on your own which caps would be most appropriate to buy. While I understand everyone suggesting the subcards (because of their wonderful sound), those people seem to be ignoring the realities of the taping situations you find yourself in. Yes, in a perfect world, we'd all be dead center and in the sweet spot - but as much as we try to make that happen, as you say, we're often taping from less than ideal positions. For those "less than ideal" conditions, I think you'd be happier with a set of hypers rather than a set of sub-cards.
as far as the pre-amp route, yes, it'll make a big difference. getting something like an Aerco or a Sonosax would be nice and compact (I think the Aerco more-so than the Sonosax, although I'm not sure of the dimensions offhand). and by getting a pre-amp, you'd be replacing the Denecke PS-2 and the Hosa transformers, which would clean up a bit of the cable mess as well. on top of that, you'd be getting cleaner gain then you could get with the R09 (and definitely better than adding gain in post).
some suggest the caps with nbox?
the nbox is a custom made box (not by schoeps) that will allow you to run the Schoeps caps without a pair of Schoeps bodies (or without a VST62 stereo body). the advantages is that it allows you to run different caps, and you don't need the bodies. With this setup, you wouldn't have a need for the Aerco, as you'd just run "schoeps caps > nbox > r09", certainly a nice and compact rig. However, the decision on which schoeps cap to buy should NOT depend on the whether or not you go the nbox route. What I'm saying is, regardless if you go nbox, or regular caps > kcy > VST62, or the ccm route, the same type of capsule will be more appropriate. You should choose that first, I'd think.
now, because you say that you are planning to keep the 4022's, I'd recommend going the ccm route (either the ccm41 or the ccm21, whatever you decide you need, hypers or subcards), and picking up an Aerco. The aerco would be a great option for both the Schoeps ccm series, as well as the 4022's that you already own.
