For sale an river AK120 modified by red wine audio in RWAK 120-S
IN PERFECT CONDITION
i get all accessories and packages.
the ak 120 were bought 6 months ago and the modifications were made 1.5 months ago
The improvement are spectacular also on hifi system!!!
The goal of the RWAK120-S modification is to transform the stock AK120 into the ultimate digital audio player (DAP) used exclusively to send a line level output signal to a portable headphone amplifier.
They achieve this by:
- 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") stereo 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
Unfortunatly i have to sell it for personal reasons.
