Amplifier Test

A given headphone output may accommodate many different headphones - in general, a smaller load impedance (on headphones) will lead to a larger sound, but at cost of accuracy in measurable data due to the increased current - this cost usually manifests in an increasingly weak bass and elevated crosstalk values as the load impedance decreases. The purpose of the tests to follow is to see how these values change as a function of impedance.

R33:33Ω / R62:62Ω / R250:250Ω

Sampling Frequency : 44.1kHz /  Apple - iPad2

R33:33Ω / R62:62Ω / R250:250Ω

Test Mode : 24bit, 44.1kHz

  

 

Output Impedance

A lower impedance is desirable on the headphone outputs of amplifiers. The output impedance is closely related to the damping factor, and is one of the most important parameters that determine headphones' performance - desktop amps tend to exhibit high impedance values, corresponding to poor performance.
