From another not serious audiophile but rather very enthusiastic music listener, I can only recommend the DX160. It simply clearly upgrade the enjoyment for all of my gears and wow me away. I still remember a couple of days when I was first trying it, I kept having this thoughts like "Wow, What, this is freaking serious" and enjoy music like I never before (except for concerts of course). Moreover, it impressed me so much I haven't got a second thought and not look for anything more. It's that satisfying. Btw, my previous DAP is Plenue D which is a very good one at sonic performance as well.
I dont know about how the Sony sounds but from what I see, if you budget allow you a DX160, then simply get it and put the Sony out of the equation. If you want to look for something else though, maybe Hiby R5, Fiio M9.
Streaming with Tidal and Spotify is mostly good for me. Sometimes, rarely, there is cut off but maybe just some wifi issues. Doesn't bother me much and I dont care enough to look into it.
Another important point is, with this DAP, it is hard to find the need for buying audio stacks (DAC, Amp combos). You can use this one as DAC for Mac or Windows or you phone, either bluetooth(5.0, AAC, LDAC, Aptx -HD,...) or wired. It has balanced output as well and powerful enough to drive 300 ohm headphones and maybe even more.
