The D1 includes a headphone amp based on the TI OPA2134 low noise opamp. This headphone amp is able to provide low-impedance, high-fidelity audio to a wide range of headphones. We've found the sweet spot for the D1 is headphones that measure between 20 and 300ohms. The resistance of a pair of headphones can tell you a little bit about how much power they need, though other variables do have an impact as well. We have heard from customers with headphones measuring as much as 600ohms who say they're happy with the output of the D1.
