The German company AQVOX Audio Devices has produced an innovative moving-coil/moving-magnet solid-state phono preamplifier, the Phono 2Ci, that's as intriguing for its technology and performance as it is for its relatively low price: $1400. The zero-feedback, op-ampfree circuit uses a compact switch-mode power supply that's built into the chassis and features conventional voltage gain for moving-magnet cartridges via its RCA jacks, and current gain for moving-coil cartridges through the balanced XLR inputs. Rear-panel switches select between RCA or XLR inputs and offer a convenient ground lift. Either the single-ended or the balanced outputs can be used with either input. Unfortunately, the tight spacing of the RCA input and output jacks, which are mounted on the circuit board, will somewhat limit your choice of cables: Pairs of thick-barreled plugs will have difficulty fitting.
"Everybody's gotta get into the act!" Jimmy Durante used to say. That's what's happening with phono preamplifiers—they just keep being built, and I keep getting them for review. Up for evaluation in next month's column are new models from Perreaux, Musical Fidelity, Graham Slee, and a Chinese one, Ming Da. You can bet there'll be more.
I first spotted Audia Flight's exquisite-looking two-box phono preamplifier ($6100) at last year's Hi-End show in Munich, and now that Musical Sounds is importing Audia Flight gear, a review of the Phono seemed a good idea. I know nothing about Audia Flight or the designer, or what Italian audiophiles think of them, but the more time I spent with the versatile, exquisitely built Phono, the more I liked everything about it.
Audio Research's long-promised "final statement" phono preamplifier has finally arrived, and its price is $3500 less than the originally rumored $10,000. That's a pleasant deviation from the audiophile norm, but at $6495, the Reference phono still boasts a steep ticket. That's more than twice the price of the $2495 PH3 SE, AR's previous best—a class sonic act itself.
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.
Some of the most innovative thinking on hybrid circuit design these days seems to come from Russian designers. As a group, they are technically very well educated, pragmatic, and unfettered by American high-end didacticism.
It's not every Consumer Electronics Show that someone introduces a $29,000 solid-state phono preamplifier—and I miss it. The 2002 CES was one. My show report in the April issue made it seem as if I'd found out about it there, but the fact is, someone clued me in after I'd returned home. I needed to come clean on that.
Why bother with three phono preamps most of us can't afford? For the same reason the enthusiast automobile magazines cover the newest Ferraris and Lamborghinis: just reading about them is fun.
"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.
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.
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.
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."
Ever since I stopped using my Audio Research SP10 preamplifier in the early 1990sits eight phono-stage tubes used to get too noisy too quicklyI tried a variety of standalone phono preamplifiers. Seeing the most service through the 1990s and 2000s were, first, a Mod Squad Phono Drive EPS, then a Linn Linto, both of which I purchased. But when I measured Channel D's Seta Model L, which Michael Fremer reviewed in the August 2010 issue, the Linto was pushed to one side. The battery-powered Seta L (footnote 1) had the lowest noise and distortion I had encountered in a phono preamplifier, and I eventually bought the sample I had been sent for a follow-up review in 2013.
At a hi-fi show in Germany a few years ago, an audio club had set up a room filled with a dozen well-known turntable/tonearm combos. I recall seeing the Clearaudio/Souther, Immedia RPM-2 and arm, VPI TNT Mk.IV/JMW Memorial, Basis 2500/Graham 2.0, Oracle/Graham, Linn LP12/Ittok, SME Model 20/SME V, and some others I can't remember, including a few not exported from Germany.
