HARBETH: Alan Shaw in conversation with Howard Popeck

Hello Alan and thank you for finding the time to respond to the following question: Why is there such diversity between audiophile values and the audio engineering establishment’s values? “This can be explained by an almost total lack of appreciation that physics – basic high school physics – governs every single aspect of audio bar […]

PIONEER: Andrew Jones interview

Stephen Mejias writes: In our September issue, I wrote about Pioneer’s excellent SP-BS22-LR loudspeaker. At just $129.99/pair (and often discounted), the SP-BS22-LR represents extraordinary value and may very well attract a wider and younger audience to true high-fidelity sound. The only thing I don’t really like about the speaker is its tongue-twister of a name. […]

PS AUDIO: Offended? Offended!

Paul McGowan … I have always smiled when I witnessed fellow designers getting offended by some engineering claim they either disagree with or can’t understand – that is until it happened to me.

BENCHMARK AUDIO: Application notes – Rules of Thumb for Music and Audio

John Siau writes: As an engineer I like to use “rules of thumb” to make quick estimates that help explain what can be expected from the physical world around me.

AUDIOPHILE FUSES: Nonsense or what?

Hello experts. I have used audiophile fuses for years in various equipment without problem, generally appreciative of sound quality improvement.

BENCHMARK: Audio application notes – Interpreting THD Measurements – Think dB not Percent!

John Siau writes: Distortion measurements (THD, THD+N and IMD) are traditionally expressed in terms of percent. But what do 1%, 0.1%, 0.01% or 0.001% mean in terms of loudness or audibility? If you are like most people you just know that 0.001% is the best of the three numbers listed above. If you are a well-trained […]
