I believe that 100 Ohms is the spec on the line-out for RCA or XLR connections, meant to connect to a discrete amp (which usually have an input impedance in the thousands of ohms). The headphone output impedance is likely far lower.

EvshrugThanks! Then I guess the Q is, "what is the output impedance for headphones?"

AlanDixon> 0.1 Ω headphone output impedance.
This is a voltage gain amplifier… but did you know, with a current gain amp, you would want as much impedance as possible? https://electronics.stackexchange.com/questions/130414/low-output-impedance-vs-high-output-impedance-of-an-amplifier

TormIt would seem the OP couldn’t see my answer from March until now, either 🤷♂️ At least now he knows; I just chalk it up as whatever at this point 😂

Is there a 4.4mm ballanced output? Can it handle higher loads? Sennheiser HD800 and Audeze LCD-XC, for example.
