Audioholics answers our questions about the importance of audio measurements and reveals which amplifiers, subwoofers and loudspeakers have measured best. AH: Audio measurements (if done properly) ...

It’s been a while since the last installment in our Know Audio series, in which we investigated distortion as it applies to Hi-Fi audio. Now it’s time to return with part two of our look at distortion ...

A critical measure for all audio components is distortion, typically specified as total harmonic distortion (THD) or total harmonic distortion + noise (THD+N). THD is defined as: ... THD+N is the rms ...

As a former telecommunications electrical engineer, I come from a profession where analytical analysis and measurements are a necessity when designing a new product. Working for one of the largest ...

Recently I've done a collection of measurements and tests on interconnect cables to see what I could find that would explain the sonic differences that many people, including myself, have grown ...
