I was walking through the woods one day when I happened on a large, flat rock near the base of an old ash tree. Conditioned as I am from such rambles with my daughter, whose interest in wildlife echoes that of my own childhood, I bent down and lifted one end of the rock, hoping to catch a glimpse of some exotic creature or another: perhaps a delicate ring-necked snake, or a plasticky-looking red eft. The rock came loose without too much effort and teetered on its broadest edge, but before I could let it flip to one side, I recoiled in horror: There, amid the millipedes and ant larvae, was a cluster of teeny-tiny, nasty-looking old men, writhing in such a tangle that I couldn't even count them. They were bespectacled, to a one, and mostly bald—I could tell quite easily, despite the berets worn by some of them—and each pair of feet was shod in a teeny-tiny pair of off-brand Birkenstock copies, with thin, shiny black socks underneath.

The Manley Steelhead tube MM/MC phono preamplifier was first demonstrated at the 2001 Consumer Electronics Show. Nine months later, my long-promised review sample of Eveanna Manley's new baby was delivered. While Ms. Manley may have given birth to the audacious product, it was conceived by the company's chief hi-fi designer, Mitch Margolis.

Not being fond of self-flagellation, I don't usually do analog. I am not a fuddy-dudley, nor am I especially fremerous.

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.)

This tiny, lightweight, battery-powered jewel is loosely based on Nagra's VPS phono stage that I reviewed in October 2008 but uses bipolar transistors instead of tubes. The bottom of the company's familiar brushed-aluminum case has a grippy rubber material die-cut to spell Nagra. It's intended to keep the preamp from sliding, but stiff cables will have the BPS hanging in the air if you're not careful. The BPS costs $2399.

Not that many years ago, it seems, every sound crew in Hollywood and around the world recorded production sound using a compact, open-reel analog tape recorder made by Nagra. The first iteration of the Swiss-made machine appeared in the early 1950s. Shortly thereafter, with the addition of an inaudible recorded tone that allowed easy syncing to picture, the Nagra recorder became the industry standard, and remained so through the 1980s. To this day, Nagra's line of audio products retains the look of those early recorders.

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.

If compact discs are so damned dynamic and vinyl is so dynamically limited, why do they sound just the opposite? Why do LPs sound so "live," so explosive, so "there," and CDs so dead? Even the best CDs usually sink to second-rate when you switch to their vinyl versions. I've heard it, you've heard it. Only those in deep denial, those who refuse to listen, don't. They'd rather read the published specs and consider the actual listening some kind of mass delusion among Luddite LP fans.

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.

PS Audio's first product, back in 1973, was a standalone phono stage; more recently, their PCA-2 preamp had an optional phono board. The GCC-100 integrated amplifier that I review this month has no room inside for a phono board, so they've gone back to producing a separate phono stage: the GCPH ($995). Like the other products in PS Audio's current line, this one is based on the Gain Cell, one module on the input side connecting to the cartridge, followed by a passive RIAA curve (with a claimed accuracy of 0.1dB over the 40dB range of the curve), and another Gain Cell on the output side.

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.

With quiet elegance, the Sentec EQ11 phono stage and equalizer entered my expanding world of gramophone dreams. The EQ11 ($2500) is a modestly sized, tubed phono stage with the industry-standard RIAA phono equalization and five other EQ curves. These additional curves are for records pressed by companies that did not fully or promptly comply with the new, supposedly global industry standard introduced by the Recording Industry Association of America (RIAA) in 1954.

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.
