Matrix Audio X-SPDIF 2 (USB - I2S interface)

Hey Joel, how did you confirm this? Did Matrix confirm or is it easy to spot the I2S isolation on the board when you open it up?

Edit: Matrix confirmed with me via email that only the SPDIF outputs are isolated, not the I2S.

“Because the IIS interface needs to transmit very high bit rate data, the bandwidth of the current isolation scheme is not high enough.Therefore, if the IIS interface is added with isolation, the output quality may be affected when playing a high bit rate signal.”
