@mstrauss You will benefit from using a 'reclocker' between your iPhone and your DAC. There are a number of options like the Sonore microRendu, Wyred4Sound Reclocker, SoTM, etc.
This will not only solve the problem you are trying to address, but also improve overall sound quality and musical performance. A true win - win with a small additional investment.
The 'reclockers' come with their own power supply, which can be upgraded to a linear power supply for even greater sound quality improvements. See how you like overall performance via the stock switch mode supply (wall wart) and decide accordingly. It is a worthwhile second future step.
Whichever device you go with, check with Peachtree for compatibility (or the manufacturer of the reclocker).
Good luck.
