Lots love for the Purple Action here, one of the best compressors for making drums punch through the mix, its kind of like a 500 series alternative to a Distressor, although not as versatile. Works particularly well for parallel compressing kick and snare.
The BAC500 is also really good as a tracking compressor, and is pretty much the closest thing to a 1176 in the 500 series format that ive heard. Liking it on vocals and bass especially.
Also really liking the Chandler Little Devil compressor, really nice and thick sounding unit.
