Note.

Please keep in mind that the following data are from a test unit reviewed by Golden Ears. The test unit is not necessarily a representative sample of the model being reviewed.

 

When headphone out was tested, the internal mixer was set -3dB so as to counteract the amplifier’s gain.

Headphone out

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.

 

1. Headphone Output 

 13.FR_Load_Lynx_Hilo_24_44.png

R16:16Ω / R33:33Ω / R62:62Ω / R250:250Ω

Sampling Frequency : 44.1kHz / Lynx Hilo

 

 14.TB_Load_Lynx_Hilo_24_44.png

R16:16Ω / 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.
