Glad to see it helped. I was never good at describing PRaT, maybe Danny could chime in on this one. Note decay is a bit DD-like so it's slightly pro-longed it's definitely not your typical armature hit-and-run
I somehow omit this question. Sorry. Firstly thanks for kind words! I really hope you guys will like them! While Ei.xx works wonders in EDM I had incredible fun listening to some metal and hardcore. Drum kicks, low-tuned guitars makes you want to hammer some drywall :) for jazz it creates more "smoky-club-like" atmosphere I would say. Vocals in general should be more upfront and foward then on Ei.3.
Personally I wouldn't call it side grade either. Harmony 8 would still be better in my book, simply because there much more details and soundstage is more outside of your head while general signature is fairly similar (to 8non-pro).
