Twice in the last month I have been at someone's house, servicing their turntable, when they asked whether they should be considering a new phono preamp that offers additional playback equalization curves besides the standard RIAA. My usual reaction is to thumb through their record collection, where, more often than not, I find that they don't own a single record that was cut using a curve other than RIAA.

Phono playback EQ is one of those audiophile topics that stokes some people's passions, with plenty of disagreements about how important it is. I have seen grown men get into heated discussions about the history of record EQ curves, but in truth, the subject is only likely to matter if you listen to a lot of 78s or original mono LPs pressed between the late 1940s and the mid-1950s.

During my cub reporter days at Stereophile, I was always on the lookout, casting about for midlevel analog components I might latch on to, ones that could join my long-term daily-driver reference system by complementing the character of my midlevel DeVore Fidelity Orangutan O/93 and Falcon LS3/5a loudspeakers. I was searching for these basic traits: alive and vigorous, clear and well-sorted, relaxed and natural. One of my first-ever Stereophile reviews, in the October 2014 issue, was of Sentec's EQ11 phono preamplifier, which featured six EQ choices, selectable from the front panel, Bakelite knobs, Switchcraft switches, and a gray Hammerite-paint finish.

When I reviewed the Sentec, I owned three turntables and about 300 records. But phono stage–wise, I was a beggar and a borrower, hoping a friend's phono pre or some review product would jump out of the deck and become my reference.

"The phonograph record is an art form itself," Lester Koenig wrote in March 1959, "and one of its advantages is the performance that exists uniquely of, by and for the record." Remarkably, when Koenig included this pronouncement in his liner notes to Sonny Rollins and the Contemporary Leaders, the 12" long-play record had been the dominant carrier of recorded music for less than a decade, and stereo discs had been mass-produced for just over a year.

For Koenig, this issue wasn't merely academic. Before making his name as head of Contemporary Records in Los Angeles, he had attended Yale Law School, worked as a screenwriter and producer at Paramount, and gotten blacklisted by the House Committee on Un-American Activities. At Contemporary, he set out to become a leading practitioner of the art of phonography.

My adoptive mother, Lily Mae, was a retired businesswoman and former fashion model turned stay-at-home mom and artist-painter with famously good taste in everything. She raised me to have good manners, an "active awareness of color and texture," and "an eye for form." She expected me to critique her paintings, her decorating, and her wardrobe, urging me constantly to develop "good taste in everything."

In Lil's world, a perfect day was for me to skip school and go with her clothes shopping at Marshall Field's, where it was my job to sit in a plush chair offering comments about which outfits had the best fabrics and best "complimented her form." She always said "form is bones" and fashion is about "how fabrics hang on people's bones."

The concept of streaming digital music files over distances great (as with internet-streaming services like Spotify, Qobuz, Tidal, etc.) and small (from a home-PC hard drive, NAS, or networked music server) became mainstream only recently. But it was already brewing during the late 20th century, with people illegally downloading low-bitrate MP3 files made from CD rips and coming close to killing the recorded-music industry.

That wasn't streaming exactly, or not in the current sense, because the files needed to be downloaded, stored locally, then either played out of a computer or loaded onto a portable player, but from that point forward it was a steady march to the streaming-dominated present.

Never mind Napster—the first subscription audio "streaming" service was one you probably wouldn't think of: Audible, the audio book service now owned by Amazon, which started up in 1995. I did beta testing and editing work for early-days Audible, and around that time, I started loading up home-ripped MP3 files on a pocket-sized Rio MP3 player (which by then had replaced Audible's proprietary player), using it in place of a portable CD player. This led to experiments with a PC music library/player running Linux, controlled by a Handspring PalmOS device connected to the stereo system via a Sound Blaster 16 card.

I'm going to tell a story about blind listening, because it illustrates what I consider the most important issue in today's audiophile environment. I'm going to skip the names of the participants because you probably know them. And I'm not going to name the components, because their role in this story is merely as symbols of their type. Here is what I'll reveal: We were playing LPs through an expertly curated, six-figure–priced sound system in a largish room that suited the large speakers perfectly.

The occasion was a "listening party" at a friend's apartment. The guest list included me and four of the most experienced listeners I know. The plan was for everyone to nosh lightly, drink good wine, and weigh in on a new, unnamed, not-free low-output MC phono cartridge, only available on a limited, made-to-order basis.

In 1928, Swiss engineer and inventor Jean-Léon Reutter created a clock that could run for years without human interaction or any type of external power source. The Atmos Clock required no AC power, batteries, solar panels, or hand-winding. It was able to wind itself by leveraging subtle changes in atmospheric pressure and temperature.

The design was so energy efficient that a single degree of temperature change provided enough power for two days of operation; it would take an incredible 60 million Atmos clocks to equal the power demands of a single 15W light bulb. 95 years later, the Atmos Clock is still being manufactured in Switzerland by Jaeger-LeCoultre, but like most high-precision, Swiss-made instruments, it isn't cheap. Prices start around $7500.

As an upstart journalist-flâneur, my basic urge is to step on the gas and let my '54 Buick careen down the freeway, crashing into guardrails on both sides. Old Buicks were built for that, and I would love to take readers on one of those kinds of rides.

But when I write this monthly column, I find myself aiming for a different feel, more like driving cross-country in a '70s Ford station wagon, documenting motels and gas stations. A trip where it's fun to roll easy, take in the views, and stop at every car museum, snake farm, and stalactite cave.

This month, I'm going to put some miles on the Ford's odometer as I investigate the effects of Ron Sutherland's newest current-drive creation: a $3800 transimpedance moving coil headamp called the SUTZ. Along the way, I will also re-review Dynavector's $1250 DV-20X2 moving coil cartridge and examine what might be the sweetest spot in Dynavector's cartridge lineup: the $2150 XX-2 MKII.

The other day it occurred to me that the main difference between audiophiles and more reasonable adults isn't our gear. Plenty of people have impressive hi-fis simply because they can afford them and are running out of things to buy. No, what makes someone an audiophile is the willingness to sit down in front of a pair of speakers (or with a pair of headphones clamped over their ears) and focus the entirety of their attention on listening.

The first audiophile I met lived near a sewage treatment plant on the outskirts of Moscow. It was a few months after the Soviet Union collapsed, in 1992, when I was a college senior, and I recall walking with my father to his home past block after block of the identical dingy white tenements that encircle most Eastern European cities.

If I hear it, is it real?

If your ears see,
And your eyes hear,
Not a doubt you'll cherish—How naturally the rain drips
From the eyes!
Bujutsu Sosho

The more audio gear I review, the more fascinated I become by the fact that as I listen to recorded music, I can close my eyes and see musicians on the stage at Carnegie Hall, or djembe drummers in a desert by a tent, or a bass note penetrating the Milky Way. What a gift of consciousness. And what a great hobby it is that focuses my attentions in this manner.

Whenever I do turntable-setup seminars, I complain to the participants about the lack of cartridge-pin diameter and clip-opening standards. Anyone who does their own setup has experienced it: The connection is too tight or too loose. Forcing the clip onto the pin usually results in a broken-off clip that most end users don't have the soldering skills needed to repair; in the worst case, it can even result in damage to the cartridge when you try to remove the clip from the pin.

Sometime around 483 BCE, in Kushinagar, the capital of the Malla Republic in what today is the Indian state of Uttar Pradesh, an aristocrat named Siddhārtha Gautama—known better to us as the Buddha, or the Awakened One—passed away. For 45 years, he had wandered the North Indian River Plain teaching a method of overcoming ignorance, craving, and the cycle of death and rebirth to a growing community of followers.

Three high-performance products were subjected to second opinions and/or measurements in recent issues: Channel D's Lino C 3.3 phono preamplifier, Mola Mola's Tambaqui D/A processor, and Pass Labs' XP-32 line preamplifier.

Years ago, at a San Francisco Audiophile Society gathering, I was lucky enough to spend time with the late, brilliant electrical engineer Roger Modjeski, whose Music Reference RM-200 Mk.II hybrid stereo tube amp is among my most prized hi-fi treasures. I asked him what he knew about transimpedance phono preamplifiers. He grabbed a piece of paper and a pencil and drew a detailed transimpedance phono preamp circuit, quipping, "These have been around forever, but until recently no one has paid much attention to them."
