Hey Mike!
It's nice to run into you! Thanks again so much for the loan of your iMod!

And thanks for asking me this question - it has led to my discovering that a "^" symbol was missing from my equation for calculating the OAP1611's Maximum Output Power (Vpp) for a given Supply Voltage (Vs)
Running the equation for a Supply Voltage of 9.6V, we get the following:
Max. Output Voltage (Vpp) = 0.1141*9.6^2 - 0.2816*9.6 + 7.0561 = 14.87 Vpp
Comparing the Maximum Output Power (Vpp) delivered to the headphones with your 9.6V battery to the previously calculated Vpp delivered with an 8.4V battery, we can see that the 14.3% increase in Supply Voltage (from 8.4V to 9.6V) would yield a 16.7% increase in Maximum Output Power to the headphones (from 12.74 Vpp to 14.87 Vpp).
So, yes - "a minor tweak," but a tweak nonetheless!

ZilchOmd: great chart for the battery'; now I wonder how the 9.6v battery would compare to the 8.4 v in your study. My LiPo has an extremely long life in such eaters as the Portaphile and the Stepdance, but wondering if the additional power of the 9.6v would be worth considering as a minor "tweak"
