They got back to me and they are going to try to get the firmware working for DSD 256 over 8 channels with HQ player on Linux! So we will see how it pans out.

The chip has more than enough power. 4x the power of the chip JL sounds uses. 2000 mips vs 500 mips.

Plus it can be custom programmed by the end user via an adapter module and Windows software.

They say it can even do DSD 1028! But probably only over 2 channels.

The hardware is top notch but the DSD solution may not go beyond DoP even for 2Ch. Only got vague answers from queries before. Maybe you can get him to clarify better on native DSD support.

No it's native capable over 8 channels of DSD 256. I've verified this right from the XMOS engineers. DoP is much less as it requires much higher bandwidth. Don't confuse the development board's capabilities with the chips capabilities. Because the development board is bottlenecked by the onboard DAC chip's capabilities. And they don't make that clear in the documentation.

DIYINHK is working on it. But if others started bugging them as well, they would get the hint that there's an actual real interest and demand for this

Here's the development board with the same chip, except with Ethernet capabilities. The "XE" version. DIYINHK uses the "XU" version with USB only.

And here's the "XU" chip:

I love how DIYINHK says:

"Extreme diyer can use the onboard full size XSYS connector to program the xmos with their customized firmware to add more feature and function. (Please notes the item price includes only the hardware. For programming support, please refer to the xmos official website and xcore.com for question about xmos programming, the PCB portmap is shown in the item image)"


Do we have any "Extreme DIYer's" here that can help out out with this? 🙂 I think your in that league aren't you Acko? 🙂

No doubt about the chip, it is more about the drivers provided by DIYINHK. Would like to see full DSD native support for all platforms, not just Linux.
His manual indicates DoP only for Windows and the rest is "endless possibilities" as he has put it - which means you will need to negotiate your own licensing agreement with Theyscon.
Right now I more into the vertical market but we will see ....

With Linux and OSX drivers aren't required. However the Theyscon driver is most likely required from Windows.

Once they sort out the firmware in the chip for multichannel DSD, it will be plug and play with Linux. Since a Linux based NAA is the simplest and best sounding way to listen to HQplayer, I think this will be perfect. People can still use OSX and Windows for the HQplayer server.

Sounds good! Are you able to get a sample for me to play around with the development 🙂

I'm just not sure on how fast they are gonna get it done. And maybe there's other features in the chip that can be utilized as well in your system.

Not sure if I want to do this, best you wait for DIYINHK.
The chances are his current solution will not be able to do anything beyond DoP 2Ch even for Linux or OSx, the reason why I was asking for a sample to test this out. Also, I did not get straight answers from him before, so a little ambivalent

But, I can plan for an 8-CH reclocker in anticipation.

Yeah his replies are quite short. His English seems pretty good, but not much of a chatterbug. I'll update once I hear back.
