Thank you, you're very kind!
If you'll realize that multiplexer, just tell me what i have to do to purchase one together with the other boards i signed for...
About Ebay link, i think i didn't understand how link adding works in this forum: any Ebay link i post is not working when inserted in my posts...
But to be sure you can find the board i linked, just search in Ebay for "WM8804 S/PDIF TOSLINK to IIS Converter I2S Codec Project integration DIY", exact phrase: you can't fail!

Hi Joro,

is there a chance that multichannel version will be released in the near future?

Hi Joro, Do you know if your board XMOS/AK4396 works with Raspberry PI (RaspyFi)? Regards, Marco

I thought about this... For now I haven't got plans to do such board - one of the main reasons is the driver issue - new XMOS driver is a stereo one, if one wants a multichannel driver, he has to connect directly to Thesycon.

I haven't tested on my own. One of my clients run XMOS board and PCM5102 board on Raspberry - the result wasn't very good - there was crackles on higher Fs (Raspberry is not fast enough ). The same guy use XMOS and PCM5102 boards with beaglebone black with no problems. As I said I don't have either Raspberry or beaglebone black, so I don't test XMOS board with this computers. If you gonna use it with this kind of computers, you probably have to use external power supply for USB part.

Regards,
Joro

I have a raspberry pi running a waveIO at 192khz without problems. The issue with the pi is that the USB bus is limited to supplying 140mA which just isn't enough to power the external board. Give both the xmos board and the pi a regulated 5v supply and you will get good results.

Yes, please. But you have to test it with an external power supply for the USB part.

Just to share in my efforts; I've got an XMOS/AK stack powered by duel Salas shunts. Both with SILMIC II 220uf lytic, tuning for digital use. Pardon the 'low profile' build pattern; I plan to mount all this in a low profile case.

To the sound - very very nice for the price :-) The reconstruction filter certainly gives up a bit to a traditional IV, but in other ways... Before calling it done, I'm going to add a JG Buffer. Have to say though, the DSD/PCM performance of this stack with quality power is pretty damn good. Thanks again Joro.

Nice setup MisterRogers.
What current values did you use for salas shunts:
- USB part - I presume 400 mA and 150 headroom?
- AK and clocks?

Any other tips for building salas bib?

I just received my boards and basic kits and I'm preparing to order the rest of the components
Thanks
