I use my dpa 4061's and record to not clip at the applause (which is usually the loudest part of a symphony set). If you record 24 bit you can amp up the quiet parts without hissing. and also step on the applause to make it less prominent. Kind of a long process but worth it.
Here's an upload of a couple of operatic arias I recorded using that set up. If you have good acoustics in your hall (and most symphony halls do) you'll be pretty happy with any decent omni set up at 24 b.
