Analog Corner #251: ModWright PH 150 phono stage
Michael Fremer  |  Dec 11, 2023  |  First Published: Jul 01, 2016  | 
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...

Gramophone Dreams #79: a Vintage Lenco L75 turntable & the PrimaLuna EVO 100 phono stage
Herb Reichert  |  Dec 05, 2023  | 
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."

Mytek Digital Brooklyn Bridge II Roon Core preamplifier

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.

Gramophone Dreams #76: Lounge Silver Copla, Grado Platinum3 High, Benz Gullwing SLR, Shure V-15 Type III
Herb Reichert  |  Aug 24, 2023  | 
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.

Analog Corner #255: Kuzma Stabi M turntable, Audio Tekne TEA-8695 and Xactive Argo phono preamplifiers
Michael Fremer  |  Aug 10, 2023  |  First Published: Nov 01, 2016  | 
Do good things come in small packages, or is bigger better? Your call. But regarding the products they've sent my way for review this month, designers Franc Kuzma, Kiyoaki Imai, and Velissarios Georgiadis are all in the latter camp. Kuzma's Stabi M, designed to accommodate the 14" version of his 4Point tonearm, is a massive turntable with a big footprint. Imai's Audio Tekne TEA-8695 tubed phono preamplifier has 11 Permalloy core transformers and weighs nearly 100lb. And although it uses just four signal-path tubes and a pair of rectifier tubes, Georgiadis's Xactive Argo phono preamplifier fills the full width, height, and depth of a Harmonic Resolution System shelf—and not because it's a big but mostly empty housing.

Spin Doctor 2: CH Precision P1 phono preamplifier
Michael Trei  |  Jul 05, 2023  | 
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 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 AJ—not only about audio, but about coffee, motorcycling, metallurgy, or any other of his many passions . . .

Analog Corner #258: Dan D'Agostino Momentum Phonostage & Gold Note Tuscany Gold MC cartridge

At the beginning of this century, when the vinyl resurgence was at best nascent and few believed it would be as strong as it is today, Boulder Amplifiers manufactured a phono preamplifier that cost $29,000. I reviewed that model, the 2008 (now discontinued), in the July 2002 issue. With a power supply that would probably be more than adequate for a high-wattage power amp, it was built to a standard approached by few other makers of phono preamps...

With his lines of power amplifiers and preamplifiers well established, Dan D'Agostino—the founder, CEO, and chief designer of the company that bears his name—set about designing a phono preamplifier.

Gramophone Dreams #70: Sutherland Engineering SUTZ & Lounge Audio Copla headamps, Dynavector DV-20X2 & XX-2 MKII phono cartridges
Herb Reichert  |  Feb 23, 2023  | 
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.

Analog Corner #260: CH Precision P1 phono preamplifier
Michael Fremer  |  Feb 10, 2023  |  First Published: Apr 01, 2017  | 
Although Swiss-based CH Precision is a relatively young company, its core design team has been involved in high-performance audio for many years. Their website doesn't state the company's age, but something there did provide a hint: Among the design team's previous activities was work for another Swiss company, Anagram Technologies...I hadn't made the connection between Anagram and CH Precision when Raphael Pasche, the latter's electronics design engineer, visited last fall to install CH Precision's P1 dual-mono phono stage and the optional X1, a discretely regulated, outboard linear power supply that's claimed to exhibit ultralow levels of noise. The P1 can be ordered as a stereo preamp for $31,000; add $17,000 for the identically sized X1 power supply. Or one mono P1 can be used for each channel, for $55,000 plus $34,000 for two X1s. Expensive stuff.

Brilliant Corners #2: Manley Steelhead RC phono preamplifier

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.

CH Precision's P1 phono preamplifier, which I wrote about in the April 2017 issue, is not going back to its manufacturer. The longer I used it, the more obvious it became that I couldn't part with it, even though I said I couldn't afford it. The cost was stiff even at the accommodation price (at retail, the CH Precision P1 and its optional X1 power supply are $31,000 and $17,000, respectively, footnote 1), but I decided I could afford it, and bought it for myself as a 70th-birthday present. No, I can't hear as well as I did 30 years ago, but my listening is better than ever.

Maybe you've seen the widely circulated New Yorker cartoon: Two guys stand in front of a nicely drawn, tubed audio system, under which are shelves full of LPs. One guy says, "The two things that really drew me to vinyl were the expense and the inconvenience."

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.
