If budget is of no concern, and you want great sound in a tiny package, you need DPAs...
If budget is of concern, I would recommend a set of Church Audio mics, or the AT853s... The CA mics are about the same size as the DPAs, and offer performance arguably as good as the DPAs for a fraction of the price... The ATs offer the advantage of interchangable caps for different situations and many accessories...
All three will out perform the CSBs any day of the week... As AJ said, the CSBs were acceptable a decade ago, but technology has passed them by... Time to upgrade!
As to your "warmth" question, if you are planning on micro-mics, you'll want a "warm" preamp... Talk to the guys using the Naiant TinyBox preamps and see what they say. Those are really nice and can be custom made to a variety of mics and flavors...
