Both J28 and J29 has no effect on WM8804 and DIR9001 converter board. They are only used for CS8412 and CS8414 chips.

For D1V3, J22 set to 16bit for RJ mode for SM5842 digital filter. J21 set to DEM LED off.

Hi,
REALLY A FANTASTIC IMPROVEMENT!!!!
OK, D1V3 (and D1V33 upgrade) has always been a great DAC, but now with WM8804 is better again in all the audible sensations!!
This upgrade is really a MUST!!
Thanks a lot Spencer!
Sincerely.
Davide.

I've got a D1V33 (WM8804 upgrade) too. If anyone had the opportunity to compare D1V33 vs FDA-1B, are there big sonic differences between??

Default J5, J6 and J7 switches

Hi,
in my D1V3 (with D1V33 and WM8804 upgrade) I have wired J5, J6 and J7 (Polarity Select Phase, Jitter Select, Dither Select) to relative 2 way switches in the front panel of the box.

The question is:

Can I change the postions of the switches with the DAC powered-on during the listening? Or should be better do it with the DAC powered-off?

Many thanks in advance. Best regards.
Davide.

Hi @all,

after a very long time the D1 is in his temporary housing.
The inside picture is not the actually, the output caps are now black gates.

Thanks Spencer for this DAC. The tests with "WM8804" and "NPC SM5842AP" comes later after enjoying this for now.
