Astell & Kern + Red Wine Audio RWAK120-B digital audio player

  • 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
