Lehmann Audio Linear Headphone Amplifier

A high quality headphone amplifier is as important for listening to music with a pair of headphones as are stable power amplifiers for the loud-speakers of your stereo setup. Dynamic headphones are far more different than most people realize. For the same sound pressure level the power needed with different headphone models can vary up to a factor of about 500. Impedances can be different to a factor of more than 20.

This is the reason why different headphone models have very individual requirements to the headphone amplifier driving them in terms of voltage and current. Everybody who once has connected a high quality headphone to any given standard headphone output knows about this problem.
