ModWright Instruments' PH 150 moving-coil/moving-magnet phono stage measures 17" wide by 5" high by 12" deep and weighs 19lb. Knobs on its front panel let you easily make adjustments that with some phono preamps require accessing the rear panel or going inside. Starting at the left, the Select knob offers settings for MC, MM, and Mute. The Gain knob offers levels of 0dB, –6dB, and –12dB. With MC selected, those settings would correspond with 72, 66, and 60dB of gain, respectively; with MM, the numbers would be 57, 51, and 45dB, the last being more typical of most MM stages.

First, let's talk about problems with grounding and hum...

Though Westchester County, New York, seems a likelier locale for Bikram yoga studios, pet psychologists, and pricey restaurants specializing in "grain bowls" and fermented vegetables, the idea of manufacturing audio gear there is not without precedent. Cartridge manufacturer Micro-Acoustics (Elmsford, NY) thrived there for over two decades. George Kaye and Harvey Rosenberg's New York Audio Laboratories (Croton-on-Hudson, NY) assembled Moscode amplifiers there. Even the notorious loudspeaker manufacturer Fourier Systems (Yonkers, NY and Cocytus, Hell) got their start in the county that Hillary Clinton calls home, as needed.

Designer Bill Hutchins, of LKV Research, builds the 2-SB moving-magnet/moving-coil phono preamplifier in North Conway, in the White Mountains of New Hampshire; he uses as many US-sourced parts as possible, and sells his products factory direct. I reviewed the 2-SB in March 2014, on AnalogPlanet.com: the 2-SB's sound was exceptionally fine—especially if you like refined, solid-state quiet and detail, and especially considering its then-price of $2500. Since that review's publication, the 2-SB has been upgraded with a version of the third gain stage from LKV's JFET-based Veros One phono preamp ($6500; see below), and its price has risen to a still-reasonable $3000.

In May 2014, Bill Hutchins introduced the Veros One phono preamplifier ($6500).

I still remember how difficult it was for me to transition from mass-market to high-end audio. The former, for all its flaws, gave me things to do: switches to flip, buttons to push, knobs to turn, meters to watch. I was in control—and if my attention happened to stray from the music or the liner notes, I still had something to keep me busy. By contrast, the first perfectionist-quality amplifier I bought—an Amber Series 70—was an oblong box with an on/off switch. Where's the fun in that?

Dr. Feickert Analogue's top-of-the line turntable, the Firebird ($12,500), is a generously sized record player designed to easily accommodate two 12" tonearms. Its three brushless, three-phase DC motors, arranged around the platter in an equilateral triangle, are connected to a proprietary controller in a phase-locked loop (PLL); according to the Firebird's designer, Dr. Christian Feickert, a reference signal from just one of the motors drives all three—thus one motor is the master while the other two are slaves. (Man, today that is politically incorrect, however descriptively accurate.)

At some point within the last few years of his life, the late Ken Shindo designed an outboard phono preamplifier—a decision perhaps made inevitable by his earlier decision to answer popular demand with line-only versions of the Aurieges and the more upmarket Vosne-Romanee preamps...

I used to get invited to these highly secret audio soirées, held in a basement workshop at the end of a dark, garbage-filled alley in Manhattan's Chinatown. There was no street address—only a wire-glass window in a metal door—and if you didn't know the password (ie, if you weren't carrying some type of audio amplification), you weren't allowed to enter. That said, sometimes nonmembers were allowed to attend, but only when a member needed help carrying monoblocks: There was no parking nearby.

"The way that young people will get into high-end audio is not through streaming: It's through the LP."

When that observation was offered during a recent phone conversation, I wrote it down word for word—not just because I agree with it, but because it was so remarkable: The audio-industry veteran who offered it owns a digital front end worth tens of thousands of dollars, and hasn't owned a turntable for at least a dozen years. Nevertheless, as became clear during the remainder of our conversation, he understands the dynamic that keeps vinyl at the top: a confluence of marketing psychology and genuine sonic goodness.

With quiet elegance, the Sentec EQ11 phono stage and equalizer entered my expanding world of gramophone dreams. The EQ11 ($2500) is a modestly sized, tubed phono stage with the industry-standard RIAA phono equalization and five other EQ curves. These additional curves are for records pressed by companies that did not fully or promptly comply with the new, supposedly global industry standard introduced by the Recording Industry Association of America (RIAA) in 1954.

Except for a few titles I've combined with the ones in my listening room, and a few others that I intend to sell, the record collection I bought last year remains in three rows of boxes on the floor of our guest room. Because that room is spacious and comfortable, and equipped with a small refrigerator and a flat-screen TV, it is also the place where my 16-year-old daughter and her friends have their slumber parties and Dr. Who marathons. Thus, as you can imagine, I must sometimes explain to our young guests the Tao of collecting records.

What I failed to make absolutely clear in my April column is that I really, truly, thoroughly enjoyed all three USB DAC–headphone amps that I auditioned: the Audioengine D3 ($189), the AudioQuest DragonFly v1.2 ($149), and the Cambridge Audio DacMagic XS ($199). Each offered a slightly different perspective on the music, but none could be accused of closing lanes on the George Washington Bridge, dumping several feet of snow on top of our car, or doing anything especially wrong.

Veteran phono-preamplifier designer Ron Sutherland has been partial, of late, to battery power. Getting off the grid can produce superb results, as demonstrated by his Hubble phono preamp ($3800), powered by 16 alkaline batteries.

I favorably reviewed the Hubble in the February 2010 issue, and remember loving most everything about it—particularly its drop-dead-quiet backdrops, its solid, weighty bottom end, and its fully fleshed-out instrumental textures. I was less enthused by its somewhat soft, muted high-frequency transients, though of course tastes and associated gear will differ. I need more grit, particularly for rock; you may not.

In July 2008 I reviewed the intriguing Phono 2Ci moving-magnet/moving-coil phono preamplifier from Aqvox Audio Devices. Though it then cost only $1400, the Phono 2Ci's current-input circuitry represented a high-tech departure from the typical voltage-gain circuits used by almost everyone else. Although keeping its retail price so low resulted in some sonic compromises, it sounded remarkable, and tough to beat at the price.

The Milty Zerostat: Sold for prevention of disease. And other things.

Before dropping the needle onto Christine's copy of Sold for Prevention of Disease Only, I shot the record a few times with the Milty Zerostat 3 ($100), a blue, gun-shaped gadget that helps eliminate static. Squeezing the Zerostat's thin black trigger releases positive ions; relaxing the trigger produces negative ions. A complete squeeze cycle results in a neutral static condition—one perfectly in balance, neither too heavy nor too light—and my LPs play quietly. This step in my LP-playing routine grew out of necessity and has become a habit. The process is especially important in the cold winter months, when the air in my small apartment is dry, and debris stubbornly clings to my LPs and my cartridge's stylus.

Parasound introduced their affordable Z series in 1996, the year Lisa Marie Presley filed for divorce from Michael Jackson. I was 19 years old and could have used a good stereo in my dorm room, but I didn't then know anything about hi-fi. If you're reading this in your dorm room, you're way ahead of where I was at your age. If you're reading this in your mansion, you're way ahead of where I am now.
