I got mine this morning.
Use the iphone4S to play HiRes files (like DSD, etc.) via bypassing the onboard DAC with the CCK. As the PHA-2 can decode DSD files, etc... and is an amp, this should solve this problem.
iphone 4S (Running Onkyo HF Player) > Apple CCK > USB-to-USB mini > Sony PHA-2 (DAC and AMP)
Problem With Original Setup:
1) The iPhone 4S randomly recognizes that the CCK is connected.
a) in the case when the phone does recognize that the CCK is connected (and the Sony is not powered on), the iPhone displays the dreaded "device requires too much power". This is why I have the Sony power on when I first connect the iPhone.
b) However by having the Sony powered on there is no consistent method to make the iPhone recognize the CCK
2) When the CCK does work and does pass HiRes signal to the Sony PHA-2 a bunch of power is drained from the iphone (draining the battery very quickly)
Hypothesis on how to Solve:
Use the dockStubz+ between the iPhone and the CCK. Providing power to the iPhone via the dockStubz+ will allow the phone to stay charged while passing signal to the CCK.

iphone 4S (Running Onkyo HF Player) > CableJive dockStubz+ (with miniUSB connected and drawing power) > Apple CCK > USB-to-USB mini > Sony PHA-2 (DAC and AMP)
No dice for powering the iPhone while using the CCK.
When power is connected to the dockStubz+ there is not a "too much power" message
- However signal is not passed through the CCK to the PHA-2
When power is not connected to the dockStubz+
- Signal is passed to the PHA-2.
