Features
Ultra-low distortion precision linear feedback circuit (PLFC), distortion as
low as 0.00008%!
Ultra-low noise power supply design, so that the output noise is as low as
1.3uV (APX555B measured value, not equivalent)
；
Ultra-compact design, suitable for desktop headphone system
；
High precision low temperature drift resistance, its performance is not
affected by temperature
；
High quality relays and popless sound design
；
High precision low noise 256 level relay volume control
；
*In order to make the volume more linear in actual use, the extra levels are
shielded.
