…….. but then uncomfortable when we speak of it in absolute terms

Paul McGowan: We’re comfortable suggesting sound is subjective when it comes to our differences in perception, but then uncomfortable when we speak of it in absolute terms. In other words, we believe the source of sound to be absolute. The perception of sound a matter of personal choice. The dictionary describes subjective as a central philosophical […]

KILLER SOUNDS ON A BUDGET:

Caleb Denison (Digital Trends) writes: We were excited enough to be among the first to receive Pioneer’s new Atmos-enabled Elite speaker system for review, but when the company sent along legendary audio engineer Andrew Jones to install them, that was something else entirely. The man behind the speaker’s design and engineering — whose name is stamped right on the […]

TONE ARM EFFECTIVE MASS: A cogent, scientifically based and rational explanation

Howard Popeck asked Geoffrey Owen, the driving force behind Helius Designs if he could and indeed would find the time to explain the reality behind effective mass and – in so doing – confound the misinformation, disinformation and scientific ignorance that clouds so many discussions of this topic. As an aside and somewhat mischievously, Howard […]

NELSON PASS: Circuit Topology and … the End of Science

Jim Austin / Stereophile Magazine write …. Nelson Pass is a consummate engineer, but he got his start in physics, earning a bachelor’s degree from UC Davis. As he worked on his degree, he was already an audio designer, focusing on loudspeakers—great training for a designer of audio amplifiers. Soon, in 1974, he cofounded Threshold […]

HELIUS DESIGNS: in conversation with Howard Popeck – part one

Geoffrey ….. why is there such diversity between audiophile values and the audio engineering establishment’s values? I’m not sure there is – indeed, I would argue that, more often than not, audio engineers are just audiophiles who have taken their interest to the next level and gone pro. Perhaps I should start by suggesting that […]

HELIUS DESIGNS: VTA – “As a starting point, when people refer to Vertical Tracking Angle, VTA -they usually mean Stylus Rake Angle, SRA – in other words, the perpendicularity of the stylus with respect to the groove”

Geoffrey Owen: Somewhat like Terry Wogan and his listener, I feel my first article secured one noble reader. My hope now is to double that number in this follow-up. In my last piece, I suggested the audio industry was populated by three distinct stereotypes, these being gods, gurus and mystics; the first two I’ve covered […]

NAIM: Julian Vereker – the interview

This piece was originally published in Stereophile in 1998: One of the big industry stories of 1985 was the split, both personal and commercial, between the British Linn and Naim companies. Led by Ivor Tiefenbrun and Julian Vereker (footnote 1) respectively, both companies had started up in the early 1970s. Both men held similar views, […]

HELIUS DESIGNS: Magic Pebbles, an explanation of tonearm bias and …

In my first article, I wrote about those wizened beings who occasionally materialise from the ether, intent on stretching the boundaries of plausibility with their over-active imaginations. These people would have us believe that a generous sprinkling of their particular flavour of fairy dust on your hi-fi will transport it to the realms of godliness. […]

HELIUS DESIGNS: Geoffrey Owen, founder, owner and senior design engineer writes about the 1983 Orion tone arm

The trouble with being an engineer is that one is born with a natural tendency to look at the world through critical eyes and consider how differently you might have designed the things around you had been have been given the job. But then, if ever you feel inclined to prompt such a discussion, most […]

HELIUS DESIGNS: in conversation with Howard Popeck – part two

Geoffrey ….. When it comes to listening to what you’ve designed, do you worry that you can find yourself liking something which is actually wrong? How do you keep yourself on track? In the context of tonearms it’s difficult to imagine what I could do to make it sound ‘wrong’. This part of the system […]

HARBETH: Bass response – how deep should my speakers go for a lifelike sound at home?

Mr. Alan Shaw writes ….. Ah! That old chestnut again. OK, you probably won’t believe me if I say ‘not as deep as you’ve been led to believe’ so let’s actually make some audio clips and you can hear and judge for yourself. First: I’d like you to forget all about the numbers you see […]

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. […]

VANDERSTEEN: Richard Vandersteen: Keep on Truckin’ – by Ken Kessler

First published in 1988 Richard Vandersteen doesn’t look like a typical loudspeaker designer. True, he wears glasses, but his presence suggests a longshoreman or somebody who’d be played by Gene Hackman. And sure enough, he tells you in a quasi-Dukes of Hazzard drawl that he’s been a construction worker, plumber, truckdriver, and electrician. Electronics had […]
