The rest of the parts arrived from Mouser today too, so I will make up the kits over the next while.

Folks,

In preparation for the arrival, I have rolled out a new board based on the 9023 chip with mounting positions for the JG filter. Sample shown is for my own use but if there is sufficient interest and permission from Joachim I could make more. Will come fully loaded (DAC side only). Chip is powered by 3.6V from an on-board low noise reg with options for external supply if preferred. External supply is 5-12V for chip and +/-9V to +/-15V for the filter module. Can direct connect if filter is not used. This will help with comparisons

Cheers, Acko

Me four, I like the ufl connection pads. Is the bom much different?

Default AKD23

Hi All,

Thanks for the interest!

Do not wish to flood this thread with mine. You may order this part off-the-plan from my website below. Free shipping for early birds! Just go to the AKD23 section. DAC BOM is same as ESS specs. Schematic, BOM and 9023 datasheet supplied with purchase.

Cheers, Acko

Hi acko ! Please go ahead. The buffer is already in the public domain anyway. Your board looks good.
