Amplifier Fosi V3 Mono with headphones


New member
I want to drive Modhouse Tungsten headphones from two Fosi V3 mono amps. They plug directly into the speaker terminals. To get the Tungsten will take many months because of their limited production runs. In the meantime I want to connect my Hifiman Edition XS with 18 Ohm impedance and 92 Db sensitivity to the speaker terminals. Could anybody here tell me which resistor values I would need for an attenuator and how to wire them to reduce the output power from the V3's?
