Also , I would like to share some more findings regarding Fidelizer ROM, and it is from
@twister6 that installing
@Lurker0 would further improve the width for soundstage.
So I went ahead and tried this, but I flashed
@Lurker0 after Fidelizer, and the sound decreased in performances somewhat.
Then I tried what Fidelizer said, to flash Stock, and then
@Lurker0 + set up your google store, and then enable usb debugging, disable verity, flash Fidelizer. Now it is what
@twister6 mentioned, everything good from Fidelizer and further width has improved ! So, if you have Fidelizer, make sure you follow step by step, otherwise it would not be effective
On top of that, while I had
@Lurker0 , I used google store and downloaded my Neutron again. I remember that I was asking for some playback app for PCM that allowed to customize the Latency of the DAP. So, I took my experiences from my PC and here is my set up for PCM in Neutron. I just want to share it here, so if anyone is enjoying Neutron, you may try it out. These are most important one

*Neutron* with this setting have both excellent sound performances and interfaces, if you are already used to it. In comparison to other apps that you have on the Dx200 in Oreo.
If you need to change your Digital Filter or gain, you can go into Android setting and Audio.
For anyone who doesn’t like tinkering around. You can still just enjoy Dx200 in Pure Mango mode, and that what I used to do. Until I discovered Fidelizer ROM.
