as it seems wasteful to get the above r3 board and then remove many of the components

From Soren "around USD 200 in qty 100 for the dam1121-02"
"It's an improved DAC R-2R core, without the AC input power supply and without output buffers. It also have direct support for connecting multiple units together syncronous, t.ex. for balanced used."
"Same base design, but different firmware."

His pricing seems way off - it seems to need two to make balanced output but waiting on datasheet & connection diagrams to work it out

that price is really disappointing

i was expecting about $100 in those sort of quantities or $120 +vat and delivery
the 0.05% R3 is €176

come to think of it there isn't anything else like this on the market maybe Sorens gonna just gonna sink the boot in with the first batch and see how it goes
find that price quite a bit discouraging especially when theres still mods to be made

Yep, I pretty much told him that but he waffled a bit about removing onboard PS & buffers because OEM customers didn't want them :)
It's also improved some places, i.e. with 600 uF decoupling on each vref line and support for direct coupling of multiple units.

Pretty disappointing, indeed !

actually i dont see the point in the 1021 modules if the oem was priced correctly
there could be two versions of oem and the finished headphone dac and leave it at that
oem needs to be more customiseable

did you ask him about building something more direct and simple no fpga, adjustable clks etc

Nah, the FPGA is the whole core of his design!!

So, new new firmware

And Soekris said the .99 filters will work here, so you can still use the partypak and nos filters.

Soekris also said he made a dsd filter, which is included in the new firmware.
