Default DIYINHK XMOS multi-channel

Can anyone comment on the quality of this unit, to source multiple I2S streams?
Is it any better than the miniSDP product?

(Any comments on the 8-way DAC would be welcome too!)

Thanks
James

The performance is quite typical for a Chinese product, thin laminate, good quartz resonators, but quite average soldering.
Mine worked for a few weeks, then for unknown reasons damaged - I can not see it in the system. I gave up the day and because I use only two input channels and two output channels anyway, I switched to C-Media CM6631A.

A common problem with these boards is the absence of ESD protection for the USB port. That makes them very easy to damage.

I haven't had the chance to get a good up-close look at the miniDSP boards so I can't really comment on their quality.

I have both the xmos USB and the 8 channel DAC. They don’t look that bad. I have yet to try them out. Need to order some regulator parts before I can try them out.

Which of the USB to i2S boards have ESD protection?

I can't say that I've seen such a "DIY-friendly" board, with the possible exception of the WaveIO board (I had one but I hadn't looked around for the protection).

XMOS is quite adamant about ESD protection for its chips.. They state it in all of their datasheets and they talk about it in pretty much every thread in their forum that talks about design issues.

It's a 0.5$ part.. If I were a manufacturer I wouldn't risk RMAs due to the omission of such a low cost part.
