I originally purchased it as a "secondary" bus compressor, mostly to print drum stems out of the box for some analogue goodness. And it does that job very well! The integrated sidechain EQ is a very good idea, it can be subtle but for more aggressive compression effects it gives you more room to play with, along with the compression behaviour adjustments. It can be extremely fast and grabby (wonderful!) but with longer attack and release settings, can also do more delicate bus leveling stuff. It does not mess up with the sound, but instead makes it larger (as a good compressor should). The knobs feel good and in general it's a joy to work with. Bonus points for the VU meters that light up red when more saturation is being applied!
That being said, the most mind-blowing moment was when I once sent the outputs of my Roland Fantom through it and added some saturation and makeup gain - bang! Then I realized it sounds so good on everything in general (for electronic stuff that I make) that I made it the main stereo bus compressor in my studio. It will take a LOT of money to replace it with something better, if I ever will.
If you need a versatile, great-sounding hardware stereo compressor, I don't think there's a better deal than this. Well done, Drawmer!
