I just came across two interesting articles via by John Siau, the designer at Benchmark Audio
- Do Specifications Lie? Do Our Ears Lie? Where does the Truth Lie? An Examination of Headphone Amplifier Performance Specifications
Interesting article, aims at showing how measurements can be tweaked to appear better than they really are.
- The "0-Ohm" Headphone Amplifier: The Sonic Advantages of Low-Impedance Headphone Amplifiers
According to this, a low damping factor contributes to a change in both frequency response, more distortion and a modified phase response.
NB: All measures were performed with the Benchmark DAC1 a Sony MDR-V6 and a Sennheiser HD 650. Of course, all information need to be taken with a grain of salt, especially information directly coming from a manufacturer showing the superiority of their own product, but I found both articles very informative.
