Schiit Yggdrasil

Thanks to all!!
I wanted to connect my Grace m920 to the Yggdrasil and bypass the Graces' internal dac to be able to use the multibit dac of the Yggdrasil. 
Schiit's they may know their product made a mistake and contacted me saying I could use the BALANCE INPUTS AND OUTPUTS of both devices. 
However I stream a lot of music thru my APPLE TV and SCHIIT's tells me that the APPLE TV or the APPLE AIRPORT EXPRESS will trigger the "lower spec clock b/c it is locked to 48kHz and has resampling. 
They have no suggestions on a streaming product that would not cause this to happen.
Any suggestions?  
Just how important is this clock to make a NOTICEABLE difference?

Thanks and I hope I explained my position better.

As long as you have a transport for the music, and can plug it into the Yggdrasil and then plug the Yggdrasil's RCA outputs into your Grace preamplifier's CD or Auxiliary input OR the balanced Yggdrasil outputs into your Grace balanced inputs, there should be no issue that I'm aware of.
If Schitt is saying the Apple device will trigger the "lower spec," then it  can be assumed you will hear the music under less than optimal conditions.

This topic is not relevant to analog section of the forum, it must be placed in the digital section of the forum. DACs, Apple TV, CDs, streaming music etc... this is what are you gonna talk about in analog corner? People are strange
