Gramophone Dreams #100: the Schiit Stjarna again, the Denon DL-103, the EM/IA 103 SUT

My Russian neighbor Alex forges ax heads and smokes pig chests 5' from my bedroom window. At 2:00am, shirtless, in February. One especially cold night, I woke up to the sounds of hammering and loud music. When I looked out, Alex was blacksmithing a glowing red meat cleaver blade, with Rachmaninoff plays Rachmaninoff blaring from a cassette in his boom box.

Analog Corner #221: Trinity Electronic Design & Thrax Phono Preamplifiers

The quest for vinyl quiet seems, at best, quixotic. By "vinyl quiet" I don't mean "quiet vinyl," which we now reliably get from pressing plants like QRP, RTI, Pallas, and a few others. I'm referring to makes of phono preamplifiers who set as a primary design goal electronic "quiet," ie, an absence or minimum of electronic noise. A stylus coursing through the groove of even the quietest LP still produces a considerable amount of noise.

Gramophone Dreams #99: Schiit Audio Stjarna phono preamplifier

I'd been building and repairing tube amplifiers for a few years when my first Altec A5 Voice of the Theater speakers arrived. I bought them to help me evaluate the sound of low-powered triode amps—but whoa! The moment I turned that VOT system on, I heard from 30' away the sound of either a waterfall or a large AM radio tuned between stations . . . What's the best tube tester? A 107dB/watt speaker!

Analog Corner #223: Acoustical Systems SMARTractor & Hagerman Trumpet Reference Phono Preamp

On analogplanet.com you'll find coverage of my visit in November 2013 to the 10th annual Manila Hi-Fi Show, which took place the weekend of the devastating typhoon Haiyan (Filipinos call it Yolanda). Because the people I met there are such big Stereophile fans, I wanted to be sure to give them a shout-out in this column, too.

Despite the weather, which prevented audiophiles living on other islands of the archipelago from flying in for the event, at least 2000 managed to attend. These are passionate, enthusiastic audiophiles—and the high proportion of young people, particularly among the vinyl buyers, was encouraging.

The greeting I received throughout the show was beyond my most vivid egomaniacal daydreams. I was treated so well that I don't know how to express my gratitude, other than to just say "Thanks"—and get back to work.

Analog Corner #229: Three Expensive Phono Preamplifiers, Phasemation, PBN, Qualia

Other than being well built and high priced ($15,000, $22,000, $60,000), these three phono preamps have very little in common, in design or in sound. One has vacuum tubes, including a direct-heated 5U4G rectifier tube (the Phasemation). Two are solid-state (the PBN and Qualia). Two feature separate chassis for the left and right channels (the Qualia and Phasemation). All three have outboard power supplies. Two come from Japan (the Qualia and Phasemation), one is made in the US (PBN). All three are elegantly built, inside and out. Two are physically attractive, one is lab-grade butt ugly. One has a host of convenience features, including various equalization curves and three inputs (Phasemation). One offers no adjustability whatsoever (Qualia). One has two gain settings and multiple loading options (PBN). Two are designed to be used only with moving-coil cartridges, while the third (Phasemation) can also accommodate moving-magnets. One is fully balanced and dual- differential (PBN), two are not.

Brilliant Corners #24: Consolidated Audio "Monster Can" & Fairchild 235 MC Step-Up Transformers

One of my favorite things about this pastime is the modesty of its aims. Despite the sometimes-astronomical sums spent on gear, and the small handful of drama queens who populate various corners of this hobby, all we're doing is trying to enjoy recorded music at home. No one here is reversing planetary warming or solving the Riemann hypothesis. The sole purpose of the pursuit we write about in these pages is to please, enlighten, and entertain. I like that about it.

This means that aesthetics matter. During a recent trip to Japan, I found myself marveling at the many vintage audio components used in both public listening spaces and people's homes, and the high prices these meticulously restored devices command. I found many of them lovely, the patina of age only adding to their allure. In the West, where we believe in eternal progress, it's common to ask whether these components' performance is up to contemporary standards. "Sure, it looks cool, but how does it sound?" we might ask, as though the physical beauty of the gear is a distraction or, worse, a ploy. Recall the old audiophile joke about the initials of the design-forward Danish manufacturer Bang & Olufsen standing for "beauty only."

Analog Corner #232: HiFiction Simplicity II tonearm, Miyajima Labs Madake phono cartridge, Rogers High Fidelity PA-1A phono preamplifier

In my January 2014 column, I reviewed HiFiction's Thales TTT-Compact turntable and Simplicity tangential-tracking pivoted tonearm, an intriguing combo from Micha Huber, a talented Swiss watchmaker turned turntable designer.

The TTT-Compact's particulars, including its battery-powered motor and exceptional ease of setup, are described in detail in that review, which includes a link to a useful animation that shows how the design, as Huber says, "reduces the perfectly tangential tracking to pivot points, while the pick-up cartridge is taken and aligned on the Thales' Circle."

Suffice it to say that while the HiFiction tonearm is named Simplicity, its design is anything but.

Moon 891 streaming preamplifier

No fewer than eight boxes, powered by six after-market power cables, comprise my current reference front-end. As much as separate boxes can afford superior isolation and provide far more room for visionary engineers to work their magic, the advantages of a single box, which requires a single power cable and far fewer after-market interconnects, are obvious.

Enter Simaudio's Moon 891 network player/preamplifier ($25,000; footnote 2). Also called a "streaming preamplifier,"it includes a DAC that converts PCM and MQA files up to 32/384 (with 24-bit files upconverted to 32-bit) and DSD files up to 256. It also includes what Simaudio company co-owner Costa Koulisakis describes as "a fully configurable" MC/MM phono stage. Both theoretically and practically, it's an ideal solution for someone with space and/or budget constraints.
