... I haven't checked them yet, but I try to stay away from chips which are not on Digi-Key.

Digikey carries AKM parts but the AK4104 is not listed.

I just noticed that myself.
NuHorizons Nu Horizons Electronics - Electronic Components Distributor lists them but has 0 stock. My next call with AKM will be fun. . .
They are pretty cheap.

A nice piece of info for those who run Windows.

Over on the Audio-Widget list Nikolay has been working on an ASIO driver for the audio-widget (Borge's AB-1 and my USBxxxx series) I would like to let the DiyAudio world know we now have a fully open source DAC + driver for Windows.

I installed Nikolay's latest package and was able to run my USB5012 card on an Acer Netbook with Win7. I played 96k flac files using the latest foobar2000 and I will try and scrounge up a 24b/192k file later today.

The driver may need some polish but it is nice to have a fully open-source DAC, from schematic to driver. The DIY community is no longer tied to a manufacturer USB/UAC engine or limiting NDA's. Congratulations Nikolay.

that's a step in the right direction.

however, what is the supply chain like, when its in stock?

is it steady? does their stuff take a long lead time to restock? do they keep models around for a while or EOL them quickly?

if akm is 'ok' in all these regards, that's cool. but I suspect they are not quite the 'digikey friendly' company that, say, ti or wolfson or cirrus is.

although personally I couldn't care less about windoze drivers, I agree that this is a great news for the project. Which may bring lots of new people to it. Thanks and kudos to Nikolay!

BTW: will this work also on XP?

The AKM parts will be around for a long time. There has not been much action with them in the US which would explain the "spotty" availability. Interest here could change that, especially since the infrastructure is in place. And they are so cheap for what they are (don't tell them).

I prefer Linux myself but it is hard to ignore that 'other' OS. I haven't tired it on my wife's computer yet but I will give it a go later today.

We use the AK5394A ADC for the sdr-widget project. It outperforms all other soundcards based on other chips, that we have tested, in terms of quiescent noise floor and dynamic range. It is especially evident at 192khz sampling.

I would hope that the AK DAC will have great performance as well.

Yes, this works on XP but driver installation is more complicated than on win7.
