Spotify provide more selection of music choice and picks then others alike. Upgrading hardware source from quedelix is likely a DAP taken portability into consideration.not sure if this is the right place to ask.
I got qudelix 5k connected to iem (not headphone), playing spotify from phone.
Saw people say upgrading source is more important than cable, etc. For iem, what is the next source upgrade? or is qudelix is the best portable source period?
