So... it's been weeks since digikey's AKM4458 are out of stock.. and they should be in stock in another 20 weeks...
I'd hate to wait this long to finish this project. Anyone has any clue how to get them elsewhere ?

Never checked on ali indeed... But there's lot of fakes on there so... :/

Indeed it is really a disaster with the DAC. Did not expect that.  :(
We can only wait for digikey having it back in stock. AKM does not claim it EOL. I would be happy if somebody can find another source for the chip in small quantities.

Well, then heat up the solder irons!

Now just when I happened to receive the Aurora PCB the AK4458VNs seem to be gone again :(

Did anyone finish his/her build yet?

I'm super curious how well the Infinitas works under pressure :)

I’m also curious about how it behaves in the real world - seems a great solution to scaling up AD/DA without all the bells and whistles you have to buy into with standard commercial offerings, so if anyone has one up and running in the wild I’d love to hear how you’ve found it.

out of curiosity, what's the purpose of the FPGA? without it, the XMOS can't handle 32in and 32out?

The FPGA is used  for signal routing, inserting the optional DSP and clock distribution.
