Anyway I done the test on Rightmark but what am I suppose to do now? I'll just post 2 graphs which I think make sense.
The quality for this file is 223 kbps VBR...

These graphs aren't labelled. What exactly are you measuring here? And what file are you using to do the measurements? RMAA has a set of test files that you should use that will allow you to measure frequency response.

What is your setting in "Settings"-> "Sound Settings"-> "Volume"?

At around -20dB, the bass is distorted (default settings).

First one is dynamic range, 2nd one is noise level.

Hum, the setting is fine. The bass shouldn't be distorted.

I recorded some music again from RB and Apple FW using the song "This love".
Please test out for me...
