one amplifier is here almost all of RC4558 like amplified voltage integrated dual operational amplifier, the output impedance is high, heavy load characteristics are poor, Xin feeling harsh treble performance, the lack of a sense of bright, bass frequency response range and obviously inadequate. As required headphone output must fight Mount. Figure 5-41 circuit is one example.
