As I began writing this column, the terrible news arrived that Armando "AJ" Conti, founder of Basis Audio, had died of a heart attack at 59. A talented designer of turntables and tonearms, AJ was one of the warmest and more thoughtful people in the High End. Whenever I entered the Basis room at a Consumer Electronics Show, I had to be prepared to spend the next hour or more talking with AJnot only about audio, but about coffee, motorcycling, metallurgy, or any other of his many passions . . .
The AXIOM tonearm from acoustical systems (footnote 1)the company prefers lowercasehas been on my To-Review list since I spotted it at Munich High End more than a few years ago, but for one reason or another, that never happened. Until now.
I was born an obsessive reader and a compulsive tinkerer. During the '60s, I subscribed to Popular Science, Popular Mechanics, Hot Rod, Car Craft, Motor Trend, Road & Track, and (of course) Stereo Review and High Fidelity. Every one of those magazines presented articles discussing the importance of upgrading stock wiring to better-quality "premium" wires, citing improved electrical performance and greater reliability.
I have this friend, a smart, good-looking young physicist from Argentina. Naturally, I call him "Gaucho." He lives in a glistening-white steel-and-glass apartment overlooking lower Manhattan. I visit him regularly, usually with a group of audio friends, mainly to compare recordings, drink wine, and talk hi-fi.

Editor's Preface: In an article in the October 1995 issue of Stereophile, Professor Malcolm Omar Hawksford used Maxwell's Equations to develop a mathematical model describing the behavior of cables at audio frequencies. Among the predictions of this model were that for good conductors there exists an optimum size of wire for audio signal transmission, and that for a wire larger than this size an energy storage mechanism would exist. In his article Malcolm described a simple experiment, the results of which appeared to confirm his hypothesis.
Then serendipity struck. English engineer Ben Duncan, whose writings have occasionally appeared in Stereophile, sent me an article he had written for the pro-audio magazine Studio Sound. The results of a series of cable measurements he had performed seemed to confirm the Hawksford Hypothesis. We offer them here for your delight and delectation.John Atkinson
It's always a jolting, life-renewing Ka-BLAM when a new experience shatters your preconceptions of the order of things. From the moment you realize your dad isn't running right alongside you as you fly down the sidewalk on your first two-wheeler, to when you become a made man, these experiences forever alter how you view yourself and the world around you.
Nothing is more guaranteed to amuse non-audiophiles than the subject of high-end cable pricing. "I'm sorry. I don't mean to laugh at you, but...bwah ha ha haaa!" Who can blame them? Even in the hi-fi camp, there are those who are convinced that wires are no more than hideously expensive tone controls. "Hmmpf, cackle. Snort!"
Others hold that, differences in resistance, capacitance, and inductance aside (footnote 1), the whole high-end cable market is just an exercise in mass self-delusion. "Really, how much are they?"
As a longtime user of Nordost's cable and AC-power products, my ears opened wide when they released their three QKore Ground Units and QKore Wire at High End 2017, in Munich. While I've never questioned the importance of proper electrical grounding, to prevent problems with safety and noisethe latter including measurable noise generated by transformers, appliances, LED lighting, power supplies, and Bluetooth, WiFi, and cellular devicesI couldn't fathom what difference a passive grounding device might make in a high-end system that, in my case, is fed by an 8-gauge dedicated line with its own copper ground rod driven into the terra infirma of the fault-ridden Pacific Northwest.
Among the many bits of audio lore that never have and probably never will be aired in public is the story of the amp that ignited the reviewer's curtains. (I assume that at least some of you hoped I was going to say "pants.") I can't tell it in any great detail, partly because the reviewer in question is a friend (though not a Stereophile colleague), and I'm not sure how much of the story he wants out there. In any event, my object here is to offer a long-overdue apology, to all concerned, for having laughed at that story over the years, because it has now happened to menot the part about the curtains, but definitely the part about the burning amp.
Well, the obvious reason is that it has been a while since my last foray into Cableland (July 1988). Many new products have been introduced in the interim, so it appeared appropriate to once again open Pandora's Box. Those of you who still remember my speaker cable article of 2½ years ago will recollect the considerable controversy that evolved from that project.
Some of the response was quite predictable, though the venom with which it was laced was not. The manufacturers of those outrageously priced "garden-hose"type cables that I failed to rave about were more than just perturbed.
Merging Technologies' original NADAC Multichannel-8 ($11,500) is an impressive device. (NADAC is an acronym for network-attached digital-to-analog converter.) It has eight channels of high-resolution D/A conversion, and two more for its front-panel headphone jack; a cutting-edge Ravenna Ethernet input (based on the AES67 Audio over Internet Protocol, or AoIP); and, to my delight, a real volume-control knob on the front.
I should have seen this coming: Less than a year after the last time I railed against the darkness of cable reviewingthe indignity of crawling around behind my equipment rack, the tedium of comparing one wire to another, the frustration of trying to wring from the experience some fresh and hopefully entertaining observations, the horror of dealing with manufacturers whose hunger for good publicity borders on the vampiricI have once again invited into my home a cable manufacturer and his wares.
It would be an understatement to say that in 2001, when Nordost introduced their original Valhalla cables, they were a revelation for me. Their focus and resolution of detail were like nothing I'd ever heard, and revealed in recorded performances a startling energy and realism. Throw in their seemingly absolute transparency, and similarly unique levels of spatial and temporal precision, and the Valhallas established a new standard of sound quality in audio cables. Although their tonal balance was cool, as I reported in my first review of them in the November 2001 issue, they were the only game in town in terms of reproducing the feel of a live performance. I immediately adopted them as a reference cable, and they remain a reference for me today.
Last month, I wrote about Light Harmonic's use of Kickstarter to fund the final production and packaging of their Geek Out portable USB DACheadphone amplifier. The campaign raised $303,061 from 2146 backers. That success led Light Harmonic to create a new division dedicated to mass-market products: LH Labs. The Geek Out would be its first product. (Pre-orders are still being accepted.) LHL's second product would be the Geek Pulse, a "pure class-A" desktop integrated amplifierDAC capable of handling 32-bit/384kHz PCM files, as well as decoding native DSD64 and DSD128 files.
A reader once noted that I tend to stick with the same reference gear longer than most reviewers. In addition to Audience's Au24e interconnect, I've been using Nordost's Valhalla, Nirvana's S-X, and Stereovox's SEI-600II for many years. They're ancient in audiophile terms, and, other than the Audience cables, have long since been discontinued or replaced. However, they are still excellent, and conveniently define a continuum of qualities that I use to assess cables. At one end, the Nordost Valhalla is sharply focused and excels at reproducing transients. At the other end, the Nirvana S-X strips away electronic grunge, and beautifully conveys the continuity of the space and musical flow. The Au24e and Stereovox are near the middle and share manybut not allof the others' strengths.
