Analog Corner #236: Clearaudio Maestro V2 phono cartridge
Clearaudio began making moving-coil cartridges in the 1970s, and only later got into the moving-magnet business. Moving-magnet cartridge designers must now be mindful that most of today's tonearms are of medium to high mass and that therefore, to be compatible, their MMs must be of low to medium compliance and of higher mass than those of the 1960s and '70s.
Analog Corner #237: Ortofon MC A95 phono cartridge, Brinkmann Audio Spyder turntable and 12.1 tonearm
It's difficult to believe that more than five years have passed since Ortofon introduced its ground-breaking MC A90 moving-coil cartridge ($4200 when last available). The limited-edition MC A90, with its radically shaped body made of powdered stainless steel Selective Laser Melting (SLM), celebrated Ortofon's 90th year in business. The MC A95 ($6500), celebrating their 95th year, retains the A90's seductive shape, but the new body is built of powdered titanium, and thus is even more effectively self-damped.
Analog Corner #238: A Tale of Two Cartridges from Ikeda and Ortofon
But first, the blowback I expected following my February 2014 column on Synergistic Research's Uniform Energy Field Technology room treatments never arrivedin fact, quite the opposite. My own positive experience of the UEF devices was confirmed by e-mails from readers who'd already used them, and from those who'd taken up Synergistic's offer of a money-back guarantee. Skeptics will charge that what I and these readers heard is evidence of confirmation bias, but people say this about any positive remarks made about audio components priced above $500.
Analog Corner #241: DS Audio DS-W1 optical phono cartridge
Using light to read data from a disc sounds a lot like the technology behind the Compact Discbut you may be happy to hear there's nothing digital about DS Audio's optical phono cartridge. The DS-W1 uses the motions of a Shibata stylus and boron cantilever to modulate the output of its externally powered light-emitting diode (LED).

Analog Corner #242: Cornering the Vinyl Scoffers; Fuuga & Air Tight Phono Cartridges
The "Meet the Editors" panel at T.H.E. Show Newport Beach 2015. (LR): Robert Harley, Chris Connaker, John Darko, Michael Fremer, David W. Robinson.
Add to the deniers of the Holocaust and Climate Change those who say that the vinyl resurgence isn't happening.
Seriously, the pushback was bound to happen, and the bigger this so-called "hipster fad" gets, the more the scoffers sweat. In 2014, according to my sourcesrepresentatives of the world's largest pressing plantsmore than 73,985,000 LPs were pressed. That's correct: almost 74 million LPs. Taking into consideration such things as multi-LP boxed sets like The Beatles in Mono (which might be counted as a single record in terms of sales), defective discs rejected by consumers or retailers, and unsold records, of which there surely are many in the pipeline, we could cut the number in halfand still have around 35 million. That's more than a 40% increase worldwide over 2013.Analog Corner #249: LKV Research Veros One phono preamp, Triangle Art Apollo MC cartridge
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 fineespecially 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).

The review gear piles up, and it's time for a late spring cleaningnot that any dust has gathered on the uniformly excellent products covered in this column. I'll start with two very different phono cartridges.
Analog Corner #253: Mikey Gets Ortofon SPU'd
Last spring, at the High End show in Munich, I met with Leif Johannsen, R&D manager and chief designer of Ortofon, who walked me through the company's exhibition. Among the new products he showed me were two low-cost, low-output SPU (stereo pickup) moving-coil cartridges.
Leif Johannsen told me that Ortofon decided to produce two low-priced SPUs so that more people could afford them and enjoy their particular sound. Their new SPU #1 comes in two flavors: the SPU #1S with spherical stylus ($599), and the SPU #1E with elliptical stylus ($659)hence the model names.
Analog Corner #254: Audio-Technica AT-ART1000 phono cartridge
Recently, after 36 years at Audio-Technica, Mitsuo Miyata retiredby which time he'd run out of business cards. Nonetheless, when I met him in early July at A-T's headquarters, in Machida, Japan, he handed me a card. A line had been drawn through the original cardholder's name; under it, handwritten, was Miyata's name.
Japanese culture is so formal that there is a precise etiquette of how to offer one's business card: Hold the card lengthwise in both hands, gripping it between thumbs and index fingers, and present it with a slight bow. For someone with so long and distinguished a career and multiple patents to his name, Miyata's offering was casual. Later, an A-T staffer told me, with a laugh, that he'd never before seen Miyata in a tie and jacket, both of which he wore for our meeting.
Today, the inventor of Audio-Technica's new AT-ART1000 cartridge is better known around company headquarters as a gentleman farmera grower of legendary blueberries, Japanese eggplants, and corn. His home-built stereo system is also said to be pretty special. I had been invited to meet him, and to get an exclusive look at the challenges of assembling and testing the AT-ART1000.
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'Agostinothe founder, CEO, and chief designer of the company that bears his nameset about designing a phono preamplifier.
