Peter Pritchard

Today's New York Times carries a brief obituary notice of the passing of audio innovator, Peter Pritchard, on August 23 in Austin, Texas at the age of 83. Peter founded Audio Dynamics Corporation in New Milford, CT in the early 1960's. His original ADC-1 ("Tip mass: 0.6 mg. Compliance. 20x10–6cm/dyne, all directions. Playing weight: 1 gram or less in top quality arms") was a breakthrough product. Indeed, all ADC pickups were notable for their extremely high compliance and low tracking forces and he pursued this approach through a series of successful designs including the well-known ADC-10, ADC-25 and XLM cartridges. They were all based on his "induced magnet" principle, which derived from the older GE variable-reluctance cartridges that had been game-changers for affordable magnetic phono pick-ups in the 1950s.

Musical Fidelity AMS100 power amplifier

"That's just silly on so many counts, Antony."

I was talking last winter to Musical Fidelity's Antony Michaelson, who had been enthusing about his forthcoming stereo amplifier, the AMS100. It would be physically enormous—almost a yard deep—and commensurately heavy at 220 lbs. Despite its bulk, its maximum rated output would be just 100Wpc into 8 ohms. It would also be expensive, at $19,999. And to cock a snoot at environmentalists and their concerns, the AMS100's output stage would be biased into class-A up to its rated 8 ohm power, meaning that, even when not playing music, it will draw around 10 amps from a typical US wall supply of 120V. This also means that it will run very hot, making the amplifier impracticable for summer use in homes without central air-conditioning. Like mine.

Random Thoughts: On Not Saying Hello to Nori Komuro

This morning, I walked right by electrician and idiosyncratic amplifier designer, Nori Komuro, and I didn’t say a word. Not even hello. Why didn’t I say anything? I don’t know. I had just emerged from the subway, and was walking up 32nd Street, toward Herald Square, and I wasn’t expecting to see an idiosyncratic amplifier designer. I was looking, instead and as usual, at the ground, at the sky, at high-heels and at skirts. I saw plenty of those. I was pulling a small handcart carrying a box of loudspeakers. Nori Komuro and I would have had something to talk about.

“Oh, loudspeakers,” Nori Komuro might have said.

High-End Audio & the Invisible Hand

A recent e-mail from a reader asked why we list the recordings and systems used by Stereophile writers in their reviews. I responded that we do so in order that readers can place our value judgments in context, and predict how those products might sound with different ancillaries and recordings when they audition the products reviewed at their local high-end audio retailer.

Recording of September 2011: Son of Chamber Symphony

Nonesuch 523014-2 (CD). 2011. Judith Sherman, prod.; John Kilgore, John D.S. Adams, engs.; Chris Allen, Tom Gloady, Nathan Chandler, asst. engs. DDD? TT: 54:00
Performance ****½
Sonics ****

When John Adams was working on his Chamber Symphony (1992), he became aware that his son Sam was in the next room watching old American cartoons, presumably those by Warner Bros. that used music by the great Raymond Scott. Hyperkinetic borrowings from Scott's witty scores made their way into that earlier work, and now into its successor, a fact hinted at by its humorous title: Son of Chamber Symphony. There's even a moment early on in this new work when the distinctive rhythmic rumble of Scott's masterpiece, "Powerhouse," can be fleetingly heard in what is, overall, a short but very sweet triumph.

"Jazz isn't dead—it just smells funny," said Frank Zappa in 1974. Back then, in those dark days of Fusion, one could be forgiven for thinking that jazz's greatest years were over, that the form had died, or at least mutated enough, in its wooing of the huge, bucks-wielding rock audience, to be unrecognizable, or at least unlovable. Then, in 1982, fresh from Art Blakey's band (Blakey remains a seemingly bottomless well of fresh young talent; Harrison/Blanchard, too, worked with him), Wynton Marsalis's eponymous debut LP was released. This was possibly one of the most important jazz releases of all time, not so much because of its musical content as its stylistic choices: intelligent, hard-edged, fully fledged acoustic jazz in the style of Miles Davis's second great quintet. Marsalis, in fact, used most of that quintet on half of that release, the other half his new band of Kirkland, Watts, Moffatt, and brother Branford.

Sonny Clark: Sonny's Crib at 45

Photo: Mosaic Images

Sonny's Crib, by Sonny Clark, one of the most tragic and still-underrated pianists in jazz, is one of the greatest blowing sessions on a label—Blue Note—that specialized in blowing sessions, especially in the mid-to-late '50s, when this was laid down.

September 1, 1957 was the recording date, and that's not a gratuitous factoid. First, 1957 marked a pinnacle in Clark's brief career; he recorded 18 albums that year, most of them Blue Notes, as either leader or sideman. (He would die from a heroin overdose in 1963, at the age of 31, and the only surprise was that it didn't happen much earlier.)

Third Annual Emofest

A look inside the impressive Emotiva ERC-2 CD player.

Audiophiles have been buzzing about Emotiva for a few years now. The attraction is no mystery: Emotiva’s products are solidly built and modestly priced, and the company takes pride in its strong relationships with customers. Yet, other than in the usual show report, Emotiva’s products have been absent from Stereophile’s pages.

But that will soon change:

The Sony MDR-XB300, MDR-XB500, and MDR-XB700 Extra Bass Headphones

This story originally appeared at InnerFidelity.com

While perusing for new headphones to measure among HeadRoom's huge stock of sales team demo cans, my eyes fell upon the trio of Sony extra bass headphones. Having spent quite a bit of time lately with celebrity headphones that have exaggerated bass, I thought this might be a good time to hear Sony's take.

Nah, they don't need a celebrity endorsements, one of these cans thumps like mad.
