Web4 sep. 2015 · \$\begingroup\$ That's how I do that indeed :-) I would like to add that if Rl is very low you would need a very small value for V also because I = V/R so the current would become very large. So what I do is add a (power) resistor in series with the supply so that the maximum current is limited, for example to 1A. In case you have only one multimeter … WebLet's say the original output impedance is 1 ohm and the long cables add 30 ohms. For a 600 ohm headphone the damping factor would be ~19 which is really good. However for a set of 32 ohm headphones the damping factor would be 1.03, which is terrible and would lead to a lot of distortion. pots syndrome joint pain
