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.

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.

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.

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.

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.

In an ideal world, I'd have every phono section I've reviewed in the past 16 years on hand to compare with these three and with all that arrive in the future. But because I have a life, I don't, and I wouldn't even if I could, though some readers (and one retailer) have insisted that that's the only way that I could possibly be of any use to them. Ha! And for those who are concerned that I've neglected the Manley Steelhead, not so! It's still my reference.

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.

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.

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-amp–free 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.

Simaudio's Moon LP5.3 MM/MC phono preamplifier ($1400) is silly good! It has single-ended RCA inputs and both single-ended and true balanced-differential outputs. It also offers a wide range of adjustments for gain (54, 60, and 66dB), resistive loading (10, 100, 470, 1k, and 47k ohms), and capacitive loading (0, 100, and 470pF), all accomplished via a series of internally mounted jumper banks. You can even choose RIAA or IEC equalization. Removing the top plate to get to the adjustments reveals boards filled with high-quality parts for the well-isolated power-supply and signal-handling circuits.

"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.

Like the $29,000 Boulder 2008 phono preamplifier, the new Whest PhonoStage.20 with its MsU.20 power supply costs as much as a car. Fortunately for you, that car happens to be my first new Saab, which cost exactly $2737 back in 1972. The solid-state Whest costs $2595, so it's a few hundred dollars cheaper. But at only a tenth the cost, it comes closer to the Boulder 2008's performance than it has any right to. That it's good enough to be mentioned in the same paragraph should tell you something about how good I think it is. Nor did it come to me hyped by the manufacturer—it took me by surprise from the minute I first heard it. I began my listening right away, before reading anything about the circuit design.

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.

I've been meaning to review this Tim de Paravicini design for years. Finally, egged on by readers, here goes.
