How hard are you guys hitting these things? I can get that "gauze" effect from the RNC, but only by slamming it. I find the RNC to be a fairly aggressive compressor, which is why Supernice mode comes in so handy. A little goes a long way with the RNC.
I'm a bit skeptical about the Panasonic FM caps "clearing up the gauze", unless there was something wrong with the original caps in the first place. Then again, I've seen stranger things - I'll give this a try on one of my RNC's and see what happens.
