Normal headphones have an impedance of 32R per channel. The usual standard line output of 775 mV to which all quality equipment aspires will generate a power of U2 / R = 0.7752 / 32 = 18 mW per channel across a headphone of this impedance. An examination of available headphones at well known high street emporiums revealed that the sensitivity varied from 96 dB to 103db/mW! So, in practice the circuit will only require unity gain to reach deafening levels. As a unity gain design is required it is quite possible to employ a low distortion output stage. headphones , headphone , headphone reviews , 50 cent headphones , power amplifier , headphone amp , preamp , headphone amplifier , vacuum tube , audio amplifier , phono preamp , amplifiers , tube amp , vacuum tubes , stereo amplifier , class d amplifier , tube amplifier , mini amplifier , audiophile headphones , fiio e5 , sound amplifier , stereo headphones , tube preamp , tube amp kit , valve amplifier , mini amp , vacuum tube ampli
