I received my PD XM6 today, and I am really wondering if higher sample rates & bit-depths are possible on this device. Unlike my NuForce uDAC2, which can be set to 96 kHz 24 bit in OSX's AudioMidiSetup, the XM6 doesn't offer a higher sample rate / bit depth than 48 kHz 16 bit. I understand that this isn't a limitation by the OS, on my Win7 partition, the device shows the same limitations.
Needless to say, the XM6 is a well built device with excellent sound, staging and definition, and it excels the NuForce on traditional 44.1 kHz 16 bit sound material, but I also own a couple of high definition 96/24 sound files.
Is there a possibility to overcome those limitations?
Would it be better to use the uDAC2 as converter for the HiDef material, choosing the XM6 only as headphone amp via the analog path (RCA to mini-jack)?
Best regards and lots of thanks,
