X-Sabre Pro (MQA) connection with Auralic Aries G2.1

[Juhu]

Hey,

I'm trying to connect X-Sabre Pro (MQA) with Auralic Aries G2.1 as source.

Auralic doesn't have IIS, so i tried USB.
That did not work. X-Sabre was not recognized by Auralic.

Should USB connection be possible between the two? 
What's the next best option if both IIS & USB are out of the question?

Sound quality is utmost priority.

Thanks.
