WM8804 to CS8412 Version 2 Converter board details: WM8804 to CS8412 V2 Converter Board Technical Details Rev2 (updated on 13 Feb 2020)
Below is V1 details.
I have sold hundreds of D1V3 & D1V33 few years ago but I have not forgot continue support for this classical DAC using the best R2R PCM63 DAC chips and Jfet IV common gate topology. There is a new life to the old classic DAC if you upgrade the receiver from CS8412, CS8414, or DIR9001 to WM8804 which many diyers as well as hi-end audio professionals are all agreed to its best sound performance. I believe it is the best news for all D1V3 and D1V33 users as well as other DAC users because this converter board can output 4 digital modes and thus it can meet most DAC technical needs.
| 16-bit Right-Justified Mode |
| 24-bit Left-Justified Mode |
| 24-bit I2S |
| 16-bit I2S |
Please take note that there is a chance that this converter may not work perfectly or even not working in other DAC platform as there is no 100% compatibility due to different chips in different time of history. But as usual, I shall advise my best guess after reviewing the DAC circuit before you buy and provide remote trouble shoot support as usual.
