Vst sound quality

There is a huge difference between standalone and vst3 version sound quality in fl studio (maybe about other DAWs too). For example i made preset in standalone vital and opened it in fl. Sound just lost harmonics and became flat. All quality settings i found was on maximum. Is it a DAW’s problem or im making something wrong?

Something is wrong: in your fl audio path( limiter, eq…) or in your driver’s audio out( perhaps some windows bad enhancement like bass boost or drivers buffers…)
