Thank you for your advice!
I have tested these cue files in Foobar2000.They don't have problems.
I search the files with cue through my phone and listen to them again on the Poweramp:
"ALAC" don't have the problem.
"APE HIGH" have a little,but it is not worst. Most of them start a few milliseconds faster,but their endings is ok.
I search the worst one and find that its format is "TAK". But the header block isn't stored with anything large.
Is it because of the format?
