Armando “AJ” Conti, 1957–2016
As I started scripting this column, the horrible information arrived that Armando “AJ” Conti, founding father of Basis Audio, had died of a coronary heart assault at 59. A proficient designer of turntables and tonearms, AJ was one of many warmest and extra considerate folks within the High End. Whenever I entered the Basis room at a Consumer Electronics Show, I needed to be ready to spend the following hour or extra speaking with AJ—not solely about audio, however about espresso, motorcycling, metallurgy, or another of his many passions.
After I’d reviewed, within the January 2000 situation, AJ’s Basis Debut Mk.V turntable—about which I’d been lower than 100% optimistic—our relationship grew strained for a number of years. AJ, a perfectionist, had anticipated nothing lower than an ideal evaluation. But I’d had an issue with what I felt was the Debut’s less-than-full dynamic slam, which I blamed, rightly or wrongly, on its acrylic platter. Back then I wasn’t a fan of acrylic platters on costly turntables, even platters full of brass cylinders. I’m nonetheless not.
But ultimately AJ and I started speaking once more, a dialog that developed right into a friendship that I’ll vastly miss. At the June 2015 T.H.E. Show Newport Beach, he demoed his high turntable mannequin, the Work of Art, with alloy platter. The sound in that room, with Vandersteen Model Seven Mk.II audio system, subwoofers, and M7-HPA monoblock amplifiers, all pushed by Audio Research’s Reference 10 phono stage and Reference 10 preamplifier, was among the many finest on the present—particularly when the Work of Art was taking part in LPs.
That was, I imagine, the primary public exhibiting of a metal-platter turntable designed and constructed by AJ, and I bear in mind pondering that there could be extra steel in Basis’s future. Just a few months later, AJ insisted that he construct a turntable for Joe Harley, a recording engineer and producer, in addition to Vice-President of Product Development at AudioQuest. Why? In respect for Harley’s contributions to and love of music. Harley hadn’t requested for it, however AJ would not let him say no.
AJ constructed the ‘desk, then put in and set it up for Harley. It was the final time they noticed one another. The turntable (see picture) is not like another AJ ever designed and constructed—or, at the least, not like something he’d ever allowed out of his manufacturing facility. It’s an all-metal design based mostly on a spherical, minimalist plinth that helps solely the bearing and the tall steel platter. Each of the 2 tonearms is mounted by itself pod. Plinth and pods all sit on a platform supported by 4 large steel toes.
Just a few days after AJ’s dying, I obtained a name from his spouse, Jolanta, and his brother Anthony, thanking me for what I’d written about AJ on AnalogPlanet.com and explaining how Basis Audio would transfer ahead. They are resilient folks. Later, I obtained an announcement from Basis that included this: “AJ has plenty of merchandise within the firm’s pipeline which can be prepared for launch. All design, testing and prototyping work is completed with accomplished models and components already in stock.”
Is a manufacturing model of the turntable AJ gave Joe Harley among the many merchandise in that pipeline? I certain hope so.
Audio Research Reference Phono 3 phono preamplifier
Audio Research’s Reference Phono 3 phono preamplifier replaces their Reference Phono 2SE, and represents a modest however vital redesign of the circuit in addition to full beauty and systemic upgrades. However, the worth has elevated solely $1000, from $13,000 to $14,000 (footnote 1).
Built for Comfort: Using the identical substantial casing and industrial design because the Reference 6 preamplifier, which I reviewed within the December 2016 situation, the Reference Phono 3 is a big, user-friendly, tubed phono stage with an easy-to-read, inexperienced fluorescent show of beneficiant measurement. Below which can be six huge pushbuttons—labeled Power, Menu, Option, Enter, Input, and Mute—that can take you wherever you wish to go in your phonographic journey.
The Phono 3 has two independently configurable inputs, both of which could be set for 50, 100, 200, 500, 1000, or 47k ohms, in addition to, through inner sockets, a Custom setting to your selection of resistance. You can select between two ranges of acquire: 71 or 48dB in balanced mode, and 45 or 67dB in single-ended. And be at liberty to abuse the equalization settings: the RIAA, Decca, and Columbia curves are included, the latter two for use solely with mono LPs. All settings could be saved within the Phono 3’s reminiscence.
Unfortunately, ARC repeats, within the Reference Phono 3 proprietor’s guide, the misinformation being unfold by some who declare that “some early Columbia and Decca stereo recordings utilized a special EQ curve” from the RIAA curve. Since this delusion continues to be repeated, this, too, bears repeating: I spoke with mastering engineer George Bettyes, who reduce lacquers for Decca as “L” (the letter on the finish of the matrix code within the LP’s lead-out space tells you who reduce it) from 1957 by means of 1972. He advised me, in no unsure phrases, that as quickly as Decca started making stereo LPs, all lacquers have been made utilizing the RIAA curve: no exceptions. That’s why, he mentioned, LPs pressed by Decca within the UK for its US division, London Records, say, proper on the jacket, “USE THE RIAA CURVE.”
As for Columbia Records, I spoke with three of that label’s veteran mastering engineers, all of whom insisted that, with the arrival of stereo, all slicing was carried out utilizing the RIAA curve. When I discussed to one in all them that some folks have been insisting that Columbia’s earlier EQ curve was used into the Nineteen Seventies, he requested, “Were they smoking crack?”
If you favor to make use of a special curve for a selected stereo LP, you then’re utilizing the EQ settings as tone controls. Enjoy—however do not suppose that you have technically “corrected” one thing.
A perform labeled Hours, accessible through the Reference Phono 3’s Menu, logs the variety of hours its tubes have been used, whereas one other Menu choice helps you to modify the show’s brightness. And relying on the way you program it, the Phono 3’s auto-shutdown function turns it off after one to eight hours of inactivity.
While the Phono 3 will bear in mind your particular person acquire and loading settings for every of the 2 inputs, you’ll be able to simply override these utilizing the distant management. The handset additionally helps you to change between inputs, and modify the loading, acquire, EQ, and show brightness, all out of your listening chair.
Using the Reference Phono 3 was a complete pleasure, as was taking a look at it. I’m positively a fan of the brand new Audio Research look created by Livio Cucuzza, Chief Industrial Designer for the McIntosh Group—previously Fine Sounds, which owned ARC since 2008.
What’s Inside: The Reference Phono 3 is a balanced hybrid design whose sign path consists of an FET enter stage and 6 6H30 tubes (the 2SE used 4). Like the Reference 6 preamp, the Phono 3’s energy provide has solid-state rectification and two regulation tubes: a 6H30 and a 6550WE. In truth, the Phono 3 is so just like the Reference 6 in design that I’ve each motive to imagine it will measure simply as fantastically on John Atkinson’s check bench.
ARC recommends 600 hours of break-in—a protracted, very long time—probably due to the Phono 3’s Teflon capacitors. Fortunately, ARC’s Warren Gehl had put many hours on the evaluation pattern earlier than it was shipped to me.
