Hi @larisoe! - I have the gen 1 version of the Khadas on a second system and it works well. Very neutral IMHO. That said, if you mainly listen via Spotify I would suggest that it doesn't really matter what you use as the vast majority of these files are sourced from 44.1/16-bit FLAC files. As someone who has published many, many things on Spotify, I can guarantee you that these don't even sound as good as their 44.1/16 WAV originals, let alone anything of higher definition. For true HD you need to go well beyond this!
