I'm using my phone (poco x3 pro) with an avani dongle (alc5686 chip) and at the moment a pair of ve monk plus, that's been my most favorite combo lately, but I usually also use my Moondrop aria, with which I still have to test the high res files though. I use my phone's default music app. Occasionally I use eq through wavelet, but lately I've been listening to my monk plus just stock. I also have to newly test my ksc75, though I usually eq them to add a bit more bass, and I'm still not sure of how eq affects the sound from a non-tuning point of view, especially since wavelet is not parametric and I use autoeq presets

Actually, I tried Spotify premium, as well as Tidal, I even tried to A-B test them, with scarce results (couldn't notice any differences) . Then I tried my first proper flac downloads, 16 bit 44.1khz, and NOW I can really hear a difference. Songs I've listened on all platforms imaginable now have something like 50% more information in them, and everything has this sort of holographic/real feel to it, what I notice the most is the decay of sounds being so much more correct, the way the trail is still percievable even through other sounds.

I have a feeling that Tidal "high-res" isn't really the same as downloaded flacs, I'm not sure what's the weak link in the chain here (audio processing, actual bitrate due to internet connection or whatnot) but at least to me personally they don't sound the same, and I must admit that my first experiences with high res music made me very skeptical about the whole thing, and I was sure that 320mbps mp3 were all I ever needed. But now, I downloaded some new music, and some (only some) songs actually sound so much better, other sound the same (I've noticed some songs from Billie eilish in my library sound mostly the same between Spotify free and flac, go figure, maybe it's the files though)

What I've also noticed is that the first thing that's apparent is not the difference in detail/information quantity, it's the dynamics. On my phone, I thought that flacs sounded louder, then I noticed it's not that. They sound both louder and quieter, when the music calls for it. I think that has to do with the bit depth, and from what I've heard (still personal opinion) even tidal doesn't have the same bit depth of 16bit flacs, though I still need to do more testing. For now, I feel like I'm enjoying music for the first time again, and I'm just overwhelmed lol
