What I want is something at the output to have the headphones to appear to have more impedance(an attenuator, which are just resistors). I also don't want to modify the receiver's internals, and looking for a easier solution than adding buffers. Forget the comment about the resistors in parallel because that would just increase the signal power to the headphones, which I do not want for headphones that have high sensitivity that is outputting hissing. What I think I really need is resistor in series to plug into the output of the receiver, but I want to get a general Idea of the output impedance. How would you measure that? Is it difficult because its an active component?
