Heh. My favorite stealth setup:
Schoeps MK41 > KCY > Sonosax SX-M2/LS2 > M1/D100
Pick up a pair of Schoeps MK41 caps + KCY cable and get a Sax SX-M2/LS2 by either [1] sellingl the SX-M2 and buying one, or [2] paying Sax to modify your existing SX-M2.
For $2500, you have plenty of options. Try to scrounge up some stealth recordings with Neumann SKM140, DPA, Schoeps. Those are prolly my top three.
