Onkyo DX-6810 retrofit TOSLINK - 2016
Retrofit optical output (TOSLINK) to Onkyo DX-6810

The project aimed to work out whether it is possible to add digital output to legacy CD player. A bit of investigation regarding CXD2500Q chip told me that it is indeed possible. The benefit of this modification is that one can use its own DAC to enhance and compare the quality of built-in DAC or to have almost a "CD transport" :)
