Who does the upsampling??

[GoldenEar]

Hi,

 

I am using Amarra Junior in a chain of Mac mini -> m2tech hiface -> Accuphase DP 67 (dig. in.) -> Accuphase E-450. Amarra Junior only plays tracks with 44.1/16. If I set the hiface to 96/24 via AMS, the DAC (CD-Player) indicates it is receiving a 96 kHz signal. That means that some software must upsample the 44.1/16 to 96/24. Is this intrinsic to Amarra or is the upsampling done after Amarra by some part of the OS?

If Junior only plays tracks with 44.1/16 and it bypasses iTunes then it must be Core Audio.
