I tried different parametric EQ settings on Electri-Q on my computer and on Neutron amp on Android but nothing seems to quite provide the tight kick that bugged Poweramp EQ provided. Now I've EQed all my songs on my phone for correct response with my Philips SHE3580 using foobar2000 and Electri-Q on my computer and the 'subbass' EQ setting on Poweramp doesn't work anymore (since there's nothing to correct, I'd have to just lower ALL the sliders, but that somehow changes the frequency response too much). I found this 'bug' in Poweramp for Android where if you lowered many of the sliders in its EQ (as you might when doing subtractive EQing) you get more and more subbass bass boost-and this was a very tight boost, like a kick in your skull. I know that minimum phase EQ is recommended for correcting frequency response (since frequency response distortions are often themselves minimum phase in the first place, correcting with a minimum phase filter often also corrects the phase response), but what about an EQ setting that you know full well isn't a correction? For some songs I want a really strong bass boost.
