My 6 years old DAP Cayin N3 is still better than iPad Pro 12.9 4th gen (Flacbox app) using the same USB C to C cable, DAC/Amp, and speakers. The only downside is the battery. It can only play 2 or 3 albums then I need to wait for it to be fully charged about 30 minutes. I found it better when I play music very loud.
