The standard Android Audio API has an issue with upscaling 44.1khz/16bit pcm files to 48khz. It does this automatically without you wanting it to and only on standard CD quality files. This causes audible noise particularly on sensitive iems. A program like USB Audio Player Pro uses its own audio path and bypasses the standard Android API to avoid this known issue.
Also, many players don't correctly handle DSD files and will convert to PCM before sending to DAC or just won't even play them at all.
