After a couple of years, the receiver chip CS8404 of the Promitheus Audio DAC failed, replaced it by desoldering and soldering the new chip but after a few months, the chip burnt again. I decided not to replace the chip as the pcb tracks was badly damaged and some broken or detached from the board. So, I scout around for a new DAC and decided on the DIY Paradise (another local Malaysian maker) 's Monica 3. Due to revision (upgrading), it comes in 2 pcbs (probably in transition phase before the new tool pcb is ready), so I purchased one and start soldering the parts below.
The populated new version pcb (black) is pluged (4pins) onto the "old" version pcb which has the power supply regulators presoldered on it. Its another TDA1545A dac which was well reviewed.
