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.

Stereophile's founder, the late J. Gordon Holt, always had a thing for horn loudspeakers, feeling that these archaic beasts offered a "jump factor" that could never be rivaled by conventional, direct-radiating designs. A horn drastically increases the efficiency with which electrical power is converted into acoustic power, which means that for a given sound-pressure level, a smaller amplifier can be used compared with a direct-radiator, and that all distortions, both electrical and mechanical, can theoretically be much lower. Yet outside of a small circle of enthusiasts, horns never got much of a following in high-end audio, and as high amplifier power became plentiful and relatively cheap, horns largely disappeared from domestic audio use (except in Japan).

One of the finest chamber music performances I have ever attended took place this past August under far from ideal circumstances. The venue was one-month-old Field Hall in Port Angeles, Washington, a city of fewer than 20,000 people known more for its port and proximity to the Olympic National Forest than for its rich culture. Perhaps that reputation will soon change, because the performers in the concluding concert of the Music on the Strait chamber music festival included its two local founders, violinist James Garlick of the Minnesota Orchestra and violist Richard O'Neill, the newest member of the Takács String Quartet. These excellent musicians, who have been friends since high school, were joined by the superb pianist Jeremy Denk and cellist Ani Aznavoorian. These are world-class musicians who attract eager audiences to New York's 92nd Street Y and Carnegie Hall, London's Wigmore Hall, and other prestigious venues. . .

What was true for that live performance in Field Hall is also true for performances reproduced on audio systems: A system can be less than technically perfect yet still transmit with eloquence every iota of care and feeling that artists and engineers put into recordings. Perfection is not an essential component of musical truth. Inspiration is.

Lest readers think this preamble is intended to suggest some shortcoming in the component under review, the Accuphase A-300 monophonic power amplifier ($51,900/pair), let me reassure you at the outset: Time and again, the A-300, like Jeremy Denk's artistry, inspired a state of wonder. The more I listened to the A-300 monoblocks, the more I wanted to listen. In my too-busy life, every occasion for listening was an occasion indeed, a special event.

389accu.promo.jpg$13,000! You could buy two Hyundai Excels for that kind of money. Or one 5-liter Ford Mustang. Or two-thirds of a Saab 900 Turbo. How could the purchase of this Accuphase two-box CD player be justified on any rational grounds? What if it did offer state-of-the-art sound quality? Would it really be 50 times better than a humble Magnavox? Would it even be 4.3 times better than the California Audio Labs Tempest II CD player? And would it approach the sound quality routinely offered from LP by the similarly priced Versa Dynamics 2.0 turntable?

In 1995, as the compact disc enters its second decade of commercial reality, it's fair to say that the associated hardware has come of age, exorcising at last the digital gremlins of time-base jitter and quantization noise. Digital-processor maturation is particularly evident in the design of the all-critical D/A processor. The simplistic digital circuitry of yesterday has given way to considerable design sophistication that deals directly with jitter and low-level nonlinearities.

It was an audacious demonstration. For the launch of Aerial's 20T loudspeaker at the end of 2002, Aerial's head honcho and designer, Michael Kelly, had arranged to compare the speakers reproducing the recorded sound of virtuoso violinist Arturo Delmoni with the real thing. The setting was the ornate dining room of one of Newport, Rhode Island's many mansions, and, given the inevitable differences—due to the facts that a violin has a very different radiation pattern from a loudspeaker and thus excites the room differently, and that the recording inevitably gives the listener a double dose of the room's acoustic—the demo was successful. There was much subsequent argy-bargying between Stereophile's reviewers about who would review the Aerial 20T, but it was Michael Fremer who eventually wrote about it in April 2004.

There may have been a time when vacuum tubes and microprocessors seemed strange bedfellows. But nowadays—given the countless digital processors with tubed output stages, and an even greater number of tubed amps and preamps whose insides are crawling with the latest solid-state devices—we're more or less used to the idea. Here as elsewhere, hybrids are no big deal.

Are you old enough to remember when the wires connecting speakers to even the most expensive and sophisticated electronics were 16-gauge, multistrand lamp cord, and the terminals on speakers and amplifiers were just little screws? Sometimes those screws wouldn't even secure all of the wires' strands, but as long as loose strands from one screw didn't touch loose strands from the other, it was good enough . . . and back against the wall went your bookshelf speakers.

In 2013, when I first wrote about it (footnote 1), the TechDAS Air Force One ($105,000) was that company's best and most expensive turntable; it joined the handful of products that have earned an A+ in our semiannual Recommended Components feature—a rating that remained in place for six years. But too much time has passed since the Air Force One was auditioned by a Stereophile writer, so it has now fallen from that list.

The two biggest sonic jolts I've experienced involving phono preamps were from two very different ones: the Petr Mares's Connoisseur 2.0 and Boulder's 2008, which was reviewed in the July 2002 Stereophile. The first was hand-built, single-ended, housed in a wooden case, limited to 100 units, and, when I got to hear it in the mid-1990s, cost around $6000, or about $10,000 in today's dollars. The other was a feature-laden, double-chassis monument to flexibility and surface-mount high technology. It featured beautifully finished, flush-mounted mirrored buttons your fingers just wanted to press.

Let's begin by discussing what SAT's XD1 Record Player System is not: It is not a Technics SP-10R in a sci-fi–inspired plinth—although the XD1's engine does begin life as the SP-10R's basic drive system, which is stripped down to a handful of essential components, reimagined, reengineered, and rebuilt to much higher mechanical standards.

If you're going to spend a year-plus in COVID lockdown, it doesn't hurt to have a million dollars' worth of turntables keeping you company, right? That's been my good fortune. Sounds like a roomful, but it's only three: the SAT XD1, the TechDAS Air Force Zero, and the OMA K3 ($360,000, footnote 1).

You'll find this issue's cover girl either strikingly beautiful or homely. Visitor reactions fall strongly into one of those two camps, with nothing in between. I love the looks. Whatever your opinion, the K3's visual distinctiveness cannot be denied. The innards are equally unique.

Servers, servers, servers. How we who embrace digital hi-fi love them for their potential to make files and streams sound better (more alive, vital, streams sound better (more alive, vital, musical, moving, transparent) than music served from a computer. How we curse them when we experience the limitations of their software. How we despair when, shortly after ascending to Peak Digital Mastery, we download a software update that hurls us back into the Valley of Digital Unknowns.

I've climbed then slid down multiple hi-fi peaks as I've moved from computer to a Roon-equipped NUC, Roon Nucleus+, and Innuos Statement Next-Gen music servers. Along the way I've reviewed the original Innuos Statement from Portugal and the Antipodes Audio K50 from New Zealand. Now I'm exploring Antipodes's top-of-the-line server/streamer/reclocker, the Oladra ($25,000), which is designed for precise clocking, low noise, and high bandwidth.

666Artemis_Eos.jpgThough the original Artemis Systems Eos has been around for a few years, it doesn't seem to have made a big impression on audiophiles. Judging by a brief but exciting audition of the new Eos Signature and its accompanying Base Module at HI-FI '96, I found it hard to understand how it could remain such a well-kept secret. A few weeks later, to my surprise, Wes Phillips asked me if I wanted to review a pair and, throwing caution to the winds, I jumped at the opportunity. Rash move.

The movers delivered three large boxes and two absolutely huge crates. Inside the boxes were the two Eos Signatures and their external crossovers. Each crate contained a Base Module, and their appearance struck fear into my heart. I had gone too far—each one weighed 300 lbs, and together they were more commodious than some apartments in my Manhattan neighborhood. I signed for the delivery, then panicked when I realized there was no way to get these unpacked before my wife came home. Indeed, I didn't know how I was going to do it at all.

Do you travel? Commute, perhaps? Just like to listen to music privately around the house? No matter—the Astell&Kern AK240 is the luxury choice in high-resolution portable music players (footnote 1). It even comes with a lovely leather case that beautifully cradles its angular beauty. The AK240 can play all of your PCM files, up to a resolution of 24-bit/192kHz, as well as DXD and single- and double-rate DSD, natively, and can do so from its internal storage, from a microSD card, or from your computer via WiFi or a wired connection. It can also function as a DAC or USB-to-TosLink converter. I'm not so sure there's much left wanting.
