How can i calculate, or maybe estimate the coltage output of my fiio e17 if connected via either usb or iPhone LOD? I really want to know this, since I want to know whether i play too loud through my 250 ohm DT-880.
If it helps, i usually go for around 27-30/60 on 6 dB gain.
Hope you can help me out here, just need a voltage estimate for one of the channels and I'll try to do the rest myself
Thank you fellow head-fiers
