Hello.
I want to buy "Matrix Audio X-SPDIF 3"
I can't to find any information about USB port decoupling/isolating.
Does it present in "Matrix Audio X-SPDIF 3" ?

As far as I know the USB input is not isolated, but the I2S, optical, coaxial, and AES outputs are isolated.
Hope @Wei Cao can provide more detailed info:-)

Radoslav, Wei Cao, tnx for reply.

I think the USB ground might be dirty. And bring dirt into the X-SPDIF device. Because of this, disrupting the work of internal circuits.
Is it possible, or iam wrong?

Hi Vadeg.
As mentioned in the webpage of X-SPDIF3, the ground of audio output ports are isolated with the ground of USB power.
