I have couple of things that don't affect my user experience all that much but if there are simple solutions then happy to hear:
1) I don't get album art for most of my albums. Most of my albums I have ripped with "Exact audio copy" program from my CD collection. The program uses a few metadata providers for album art etc. And if this fails, I have just put a relevant .jpg file to that album folder and that works perfectly in Ibasso DX160. Some of my albums (which are not ripped like this and have good metadata) show the album art fine. And then there's basically a handful of albums that I have ripped like the others and they show the art. Such as Depeche Mode-Violator. I don't get the logic here, because that CD and .jpg is just like those that don't show the album art. At some point I thought that it shows if the filename of the .jpg is exactly as the album...but then there's many where this logic doesn't apply.
2) If there's two (or more) albums with the same album name, then they get lumped together in Album view. Like I have "Timeless" by Goldie and Sergio Mendes and they are just shown together like it's one album. Not much of an issue since it's not common and I can just remember where that applies. (edit: well this actually worse on the DX160 since the tracks are mixed
...but I'll browse artist view for those)
