I'm one of the few folks on this list with much experience with stealth mics and collecting stealth tapes:
http://zhianosatch.topcities.comHere's my super-biased personal opinion:
I'm NOT a fan of these mics. I take every opportunity to shit on them. I think they tape like goddamned pussies. They have a very light, sorta-clear sound, but I think that's their failing. They're very weak to my ears and I've heard of them having SPL-handling trouble.
4061s will run you about $750 new (powered by the DPA box, not that HEB business) and they were my upgrade from CSBs. To me, they were the only upgrade! All other options had too many flaws to make them worth my money. If you want to stay 100% stealth, I say, save your scrilla and stick with the CSBs until you can afford 4061s.
