During the last year, I've been looking for an audiophile smartphone, I've bought the Axon 7, HTC 10, MI A1, and the S9+. First of all, the Axon 7 has a good sound but I can feel the music is coming out of my car's speakers not 3d which I didn't like. The HTC 10, has a very good sound but the issue is I can feel the music being all around not symmetrical (will explain that in a bit). MI A1, not particularly an audiophile phone although it has a DAP but the hissing sound can't be tolerated although it had the best stage to me in comparison to the first two. S9+, This is the ultimate, the sound in the car feels like I'm inside a balloon, the bass comes from the middle and my back, the highs will hit super clearly (it's just like being symmetrical, I can feel the lows from behind, the high hit from the front, all neat and clean) that was not the case with my S8 last year which didn't have the Dolby Atmos, and by the way, the only phone that has enough power for me on bluetooth was this, all the others were rubbish on bluetooth and I extensively tested and tuned the phone for 3 months each currently through AUX (the bluetooth thing was extra).
