General Information
AK120 modified by Red Wine Audio as follows :
- replacing the two stock Wolfson WM8740 dac chips with the premium WM8741 chips
- configuring the WM8741s to run in “hardware mode” – eliminating the digital volume control processing
- configuring the WM8741s to use their “minimal phase digital filter” option
- hardwiring the stereo line-out signal to the 3.5mm (1/8”) stereo output jack (formerly the headphone output jack), hence completely bypassing the headphone output stage
- removing the unused digital volume control wheel and installing a higher quality 3.5mm (1/8") TRRS line-out jack that is hard-wired to the line-out signal
- installing 1000uF super-low ESR capacitor across the battery rail for increased dynamics and noise filtering
