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.

Is it my imagination, or has the low-power tube movement of the last 15 years gone hand in hand with a renewed interest in moving-coil step-up transformers? Trannies remain misunderstood or ignored by most of the audio press—requests for review samples continue to be met with genial shock, rather like tourism in the Budapest of the 1990s—but enthusiasm for the practice seems only to grow. That leaves me to wonder: Did the unquestioning use of active pre-preamps for so many years grow out of the same bad attitude that gave us all those awful-sounding high-power amps and low-sensitivity loudspeakers? You know the mindset: Parts are cheap. Gain is free. Do it because you can...

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.

Anyone who knows me will be happy to tell you: I'm very bad at letting go of anger. I hold grudges. I'm unforgiving.

The original plan, back in mid-2004, was to audition an entire Ensemble system and then review the individual components over the next two years. Most audio companies produce lines of matching products, but Ensemble takes it a bit further, with a modular approach and extensive commonality of everything from chassis to circuit boards. They firmly believe that everything affects sonic performance, and their approach helps ensure a consistent sound throughout their line.

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.

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.

I don't know Gram Slee from Gram Parsons, or which House he was in at Harry Potter's Hogwarts School, but let me tell you: If you'd just been listening to a bunch of budget phono preamps, as I had, then came upon the GSP Audio Era Gold Mk.V, you'd think someone had switched out not just the phono preamp but your entire system. You might think you were listening to a different pressing or a different cartridge. How can this be?

When we last heard from Englishman Tim de Paravicini, whose EAR 890 amp I reviewed in Stereophile's April 2004 issue, the veteran audio designer suggested that he could make a transistor amplifier equal in performance to any of his successful tube designs. Whatever else it may be, the new EAR 324 is my first chance to test that claim: a stereo phono preamplifier without a single tube in sight. It isn't TdP's first all-solid-state product: That would be the line-plus-phono EAR 312 preamplifier, introduced to no small fanfare a little over three years ago. For all intents and purposes, the 324 is a standalone version of the phono section of that $18,000 flagship: The designs are virtually identical—excepting, of course, their casework and power supplies.

The $3000 moving-coil (MC) PhD, available from Chad Kassem's Acoustic Sounds operation, is a monumental achievement that, for me, sets new standards for the cleanness and transparency possible in a phono preamp—and I've had a lot of experience with phono preamps.

"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.

Trickle-down technology is a grand thing. It's comparatively easy to build an exceptional audio component when there are no constraints on technology, cost, user-friendliness, or lack thereof, but top designers are now packing more and more of the excellence of damn-the-torpedoes components into more affordable and accessible packages. Which brings us to the Aesthetix Rhea, a tubed phono preamplifier of exceptionally distinguished lineage.

Modern hi-fi is little more than a way of getting electricity to pretend that it's music. Of course, good source components remain all-important, and even if loudspeakers are imperfect, most of us can find one or two that suit our tastes, if not our rooms and the rest of our gear.

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.

It's not every Consumer Electronics Show that someone introduces a $29,000 solid-state phono preamplifier—and I miss it. The 2002 CES was one. My show report in the April issue made it seem as if I'd found out about it there, but the fact is, someone clued me in after I'd returned home. I needed to come clean on that.
