The Milty Zerostat: Sold for prevention of disease. And other things.
Before dropping the needle onto Christine's copy of Sold for Prevention of Disease Only, I shot the record a few times with the Milty Zerostat 3 ($100), a blue, gun-shaped gadget that helps eliminate static. Squeezing the Zerostat's thin black trigger releases positive ions; relaxing the trigger produces negative ions. A complete squeeze cycle results in a neutral static condition—one perfectly in balance, neither too heavy nor too light—and my LPs play quietly. This step in my LP-playing routine grew out of necessity and has become a habit. The process is especially important in the cold winter months, when the air in my small apartment is dry, and debris stubbornly clings to my LPs and my cartridge's stylus.
Parasound introduced their affordable Z series in 1996, the year Lisa Marie Presley filed for divorce from Michael Jackson. I was 19 years old and could have used a good stereo in my dorm room, but I didn't then know anything about hi-fi. If you're reading this in your dorm room, you're way ahead of where I was at your age. If you're reading this in your mansion, you're way ahead of where I am now.
Saying that Sutherland Engineering builds a nice line of phono stages is like saying that the Porsche 911 Carrera is a nice line of sports car. The Sutherlands all share common design philosophies, features, and sonic attributes—but just as ramping up from Porsche's classic Carrera Coupe ($78,000) to the GT3 ($115,000) or the Turbo S Cabriolet ($172,000) increases the level of performance and distills the Porsche experience down to its essence, ascending the Sutherland line from the PH3D ($1000) to the 20/20 ($2200) to the Hubble ($3800) buys more of what Ron Sutherland is all about.
The Leben RS-30EQ phono preamplifier ($2695) incorporates a pair of common dual-triode tubes (12AT7) for phono gain, but breaks with tradition by using a CR-type equalization circuit rather than the more common negative-feedback type. Total gain is specified as 23.5dB, which is sufficient for moving-magnet pickups; an external transformer is recommended for use with moving-coil types. A silicon full-wave rectifier supplies heater voltage, while the rail is supplied by a 6X5GT rectifier tube.
According to Parasound's founder and CEO, Richard Schram, the Halo JC 3 began as a phono-preamp retrofit for the JC 2 line stage, with separate small circuit boards for each channel. The smaller the board, the better, Schram says, so as to attract less noise than do larger boards, whose many copper traces can act as antennas.
The all-FET, class-A, B2B-1 phono preamplifier ($1749), made in the US by Liberty Audio, is beautifully built inside and out, and comes in a heavy-duty aluminum chassis with a baked-on crackle finish and a 3/8"-thick, black-anodized faceplate. The overall build quality and physical appearance suggest something that costs more than $3000, which is probably what it would cost were it sold through retailers and not factory direct. It comes with a two-week return policy.
The phono preamplifiers reviewed this month are both affordable ($400–$1960) and highly accomplished, and the most expensive of them offers versatility that's unprecedented in my experience. Three of them are designed to be used only with moving-magnet, moving-iron, and high-output moving-coil cartridges, so I installed Shure's V15VxMR cartridge in VPI's Classic 3 turntable and listened in MM mode to all of them, beginning with the least expensive.
Far be it from me to surrender these column inches to the whims of a manufacturer.
That said, there's ample reason to break with tradition and offer the thoughts of an obscure English company called LFD, whose products may already have tripped your surveillance wires. In their "Charter to Product Commitment and Traditional Values"—which can be read in its entirety on Frohmusik's website and is signed by Bews and Hawksford (see below)—the people of LFD suggest, in so many words, that they will not manufacture goods outside of their native England; that their design work is guided by listening as much as by engineering theory; that they believe some component parts sound better than others of identical numeric value, depending on their specific role in an audio circuit; that their philosophy of circuit design is decidedly minimalist; and that they advocate the enjoyment of music on vinyl LP. That the principals of LFD have thus far avoided being burned alive as heretics is a source of wonder.
It seemed a simple and obvious question, but I couldn't get an answer out of Ron Sutherland. Why did his new 20/20 phono preamp use an AC power supply instead of batteries? I asked directly, I asked repeatedly, I tried framing the question in different ways, all to no avail. Did the AC supply make it sound better? Was it less expensive to build? Were potential customers turned off by having to replace batteries once every year or two?
Even Mikey Fremer is surprised at vinyl's current popularity. Some pundits postulate that eventually CDs will die out, and we'll be faced with the choice of LPs or downloads. (I hope not. I'm just getting used to CDs.) With abundant sources of new pop releases and a wide range of reissues on vinyl, and a variety of used LPs, every audiophile should own a turntable. And with the availability of affordable turntables such as the Pro-Ject Debut III, which I reviewed in the February 2010 Stereophile, the cost of entry to VinylLand is not very dear. The problem is that so few entry-level integrated amplifiers and receivers available today include phono stages. (The Marantz PM5003, which I reviewed in the January 2010 issue, is a notable exception.)
The minuscule electrical output of an analog signal from a moving-coil cartridge needs to be boosted before it can be converted to digital and equalized in the digital domain. Of course, you could use your current phono preamplifier and record an equalized signal to hard disk, but then you wouldn't get to experience Pure Vinyl's digital RIAA correction—nor would you be able to avail yourself of all the equalization curves provide by Pure Vinyl, of which there are almost too many to count.

As long as you're spinning an LP for your listening pleasure, and if digitizing it at a resolution of 24-bit/192kHz is transparent to the analog source, why not record and store the LP on your computer at that high sampling rate for future convenient playback via iTunes or for iPod use, or for burning to CD-R? And, while you're at it, why not record the LP unequalized and apply the RIAA curve in the digital domain, where you're not dependent on capacitors and resistors that are imprecise to begin with, and can drift over time? With no drift of phase or value, the virtual filter's results should be better than with any analog filter. And in the digital domain, you can program in any curve known, and select it at the click of a mouse. Aside from the sweat equity invested in programming it in the first place, it wouldn't add a penny to the program's cost.
This massive, two-box beauty from Denmark costs $60,000, and I wish I could tell you it wasn't really better in most ways than the already outlandishly priced and sonically superb Boulder 2008. I can't.
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.
