I use A8 with NEON. I know the mediatek chipset uses only a7 but that also has NEON and they are both of the same architecture v7 so I just use that one. And also the settings respond so I think its ok.
I have v4a speaker enabled, and i dont use extra loud because the sound starts to shatter. also prefer it without the fir filter for loudspeaker. without that one checked, i think it sounds less strained.
the graphic equalizer i set in the usual U but just adjusted sligthly until it sounds good. i dont pull the levels very high because the loudspeaker cant handle it very well. i think that is depending on your phone now. for me the midband is pulled lower than default level
