Anyone knows why the choice was made to add isolation after the buffering and reclocking, instead of isolating the I2S extracted from USB and then buffer in the FPGA and read out with high quality clock as it is done?

The isolation adds its own jitter if i understand

It's been ages since i had one of those, but is there any actual reclocking outside of the processor? I guess isolating and reclocking 8 channels would have added quite a bit of complexity to the board. And there was supposed to be a mk2...

There is no reclocking on this board. But USB data is decoupled into a large buffer inside the FPGA and read out using high quality clocks on the board. However the power domain isolation happens on the output I2S interface using GMRs which inject jitter of their own.

Wonder why the USB power isolation wasnt done at the input, leaving the I2S output to have the low jiiter clock

You should reach out to their email address on the web site. To get for access and drivers

For those who still have one of these I thought I would give an update on my experience using it with Windows 10. The ASIO driver works perfect. I did an upgrade from Win 7, so I did not even have to reinstall the driver.
Now the really good news. There is a noticeable improvement in the sound quality. I would compare it to the improvement I heard by adding an AudioQuest Jitterbug to the USB chain. I use the latest version of JRiver with no issues.
My only regret is that I did not upgrade to Win 10 sooner.

The forum with download section is still live. I was able to eventually navigate there. I did a fresh Windows 10 install recently and grabbed a windows 8 driver and it worked fine.
