SR-71 amp ohms

[flashnolan]

Will my SR-71 headphone amp drive my Proline 2500 headphones? On the RSA website it says Output Impedance = 16Ohms - 2Khz, but I think I remember reading that the Proline 2500 headphones are around 60 ohms. Any ideas?

that would be fine. i think the rule of thumb is to make sure the amp's output impedance is lower than the headphone's impedance. and in this case it is

Sorry, that is supposed to be 16 Ohms.
The SR-71 can drive loads much lower than that.
