I've had the PR20 and PR40 for a few years now, the PR20 is way more detailed in the high end than a 57, but that can make source tracks have more energy up there but with placement like you said and some basic eq - good shit. Use it on snares too. The unfizzed version already sounds better. The 57 has that more boxed in sound, the pr20 seems more open in the mids.
