Widex PureSound I'm confused

I eliminated the warble–comb effect?–from my Signia AX7s by creating a music program that turned OFF, not down, feedback management feature. also I turned off compression and wind in noise and some other feature that I forget.
Good the hear that Puresound has less processing. I’ll trial Widex for my next pair of HAs, which won’t be for several more years. By then Widex and others may have changed their formulae yet again!
