If we could get back to thread business, the board I just got finished modding is a v1.07 and for the first time I tried hooking up the display. It seems to act they way bih described when he had J1 and J2 installed. However, this has no audio output and no indication of locking or that it is receiving DSD whenever the display is plugged in at all, and regardless of which if any jumpers are installed. However, the board works fine without the display.

Don't know if there is some trick to it I am missing or what. I may have to pull the thing out of the test box and look at it on the bench again. If the display unit is bad or something, no problem, I can always pin lift or hack traces to get into the dac registers.

By the way, the reason I decided to poke around in the registers is because it still doesn't sound as good as DAC-3 (as fully expected). So it is time to see if I can improve it any more with some register tweaking.

Pins are lifted and super glue is drying. Tomorrow will get into dac registers.

Up to you guys what you want to do next. I made a list of changes I could think of to update the BOM. Don't know bih's schedule or availability to work on it. If bih is busy and if it is okay with him maybe someone can chip in to help speed it up. Thanks.
