There is change, and also continuity, at Wilson Audio Specialties, the company founded in 1974 by recordist and loudspeaker designer David A. Wilson. David's son Daryl Wilson was appointed president and CEO in 2016. David Wilson passed away in 2018. And in 2019, Wilson Audio Specialties released the Sasha DAW loudspeaker ($37,900/pair), designed by a team led by Daryl Wilson and named in honor of his father.

What kind of creature is this? Gryphon Audio Designs' new Ethos ($39,000)—pronounced EE-toss by its Danish manufacturers—is marketed as a CD player and digital-to-analog converter. It's decidedly au courant in that it includes two 32-bit/768kHz ES9038PRO Sabre DAC chips—one for each channel—with each holding eight individual DAC chips; offers optional upsampling to either 24/384 PCM or DSD128; and decodes up to 32/384 PCM and quadruple DSD (DSD512) via its USB input, or up to 24/192 (and no DSD) via AES/EBU or S/PDIF.

What's the point of reviewing a pair of monoblock amplifiers that costs more than most people spend on two or even several cars— and far more than most audiophiles spend on an entire music system? That's a good question. Another is: Why should I write this review when, just seven years ago, I reviewed a pair of darTZeel monoblocks that look exactly like this new pair?

I realize that products such as the darTZeel NHB-468 ($170,000/pair) are for the very few, but the very few include far more people throughout the world than you may realize— people who can afford such costly audio products and who do buy them. I know, because in my travels I've met a lot of them, and they deserve to read reviews of products they're considering buying—things most of us can only dream of owning.

Earlier this year, I had the opportunity to spend a couple of afternoons listening to a system built around the late David Wilson's magnum opus, the Wilson Audio WAMM Master Chronosonic loudspeaker ($685,000/pair), which Jason Victor Serinus reported on in December 2016. In addition to the joy of simply listening to music on such exotic speakers, the experience provided insight into just how well the Master Chronosonics would work in a relatively normal-sized listening room—in this case, one measuring 21.5 feet long by a little over 18 feet wide, with a ceiling height of a little over 9.5 feet: not small in an absolute sense, but a lot smaller than the sort of space usually associated with speakers this large.

CH Precision's massive, versatile, technologically sophisticated, 165 lb M1.1 power amplifier ($54,000 configured for stereo) can easily crush your foot if you're not careful when installing it. But the more important consideration is this: Can this cool gray techno-square sing and dance without stepping on its own feet?

I first encountered Verity Audio's Monsalvat Amp-60 stereo power amplifier ($58,000) in October 2017, in one of the largest single-system rooms at the Rocky Mountain Audio Fest. After hearing the Amp-60 and Verity's Monsalvat Pre-2 preamplifier drive Verity's Lohengrin IIS loudspeakers ($133,000/pair), I enthused about the "most impressive range of colors and supreme sense of spaciousness" that contributed to the system's "absolutely beguiling" sound.

There's no place for fashion in epidemiology, aeronautical engineering, or the mining and storage of uranium. Fortunately, domestic audio is less serious, its goals more scattered and ambiguous, than those and a thousand other pursuits.

And so, throughout the 20th century, any number of trends in domestic audio popped up their heads, some remembered as fads, others as legitimate approaches to playback. Among the latter are amplifiers whose output sections operate in single-ended mode, in which the entire signal waveform is amplified by a single device.

Doug White, of Philadelphia-area retailer The Voice That Is, has been a fixture at US audio shows the past few years, where he always gets great sound using loudspeakers from Tidal Audio. (There is no connection between the German audio manufacturer and the music-streaming service owned by Jay Z and Sprint.) In early 2017, Herb Reichert, Jana Dagdagan, and I visited White and spent a delightful afternoon listening to Tidal's then-new Akira loudspeakers. I promised myself to review the Akira, which costs a wallet-straining $215,000/pair, when my schedule opened up. As things turned out, it was more than a year before that opportunity presented itself.

I am finding hard to grasp that it is almost 50 years since I first went to a hi-fi show. That show, held at London's Olympia exhibition center, was notable both for Yamaha's launch of a loudspeaker with a speaker diaphragm shaped like a human ear, and for being the first time I saw the drop-dead gorgeous Transcriptors Hydraulic Reference turntable, which was later featured in the film A Clockwork Orange. The most recent show I attended was AXPONA, held last April in the Chicago suburb of Schaumburg. There I saw no ear-shaped drive-units, but the final room I visited featured sound that the 1969 me could have only fantasized about.

In 1959, in their musical revue At the Drop of a Hat, the British musical-comedy team of Flanders and Swann sang their "Song of Reproduction." It's not about sex. The song mocks audiophiles (you thought this was something recent?) for how we spend "all of that money to get the exact effect of an orchestra actually playing in their sitting room." Before launching into the song, Flanders quips, "Personally, I can't think of anything I should hate more than having an orchestra playing in my sitting room!"

Some of my reviewer colleagues would have you believe that negative reviews are the most difficult of all to write, and that positive reviews fairly write themselves. What nonsense!

As I write this, my copy deadline is three days away, yet I've succeeded at crafting little more than my heading (easy enough: it's just the product's name, followed by my name) and my Associated Equipment sidebar (also easy), leaving a great expanse of nothing in between. That's mostly because the Kalista DreamPlay One, a two-box CD player whose $43,000 price might once have kept me from even considering it as a real-world product, has stunned me into a sort of paralysis: I feel that anything I write will be inadequate to the task.

Not everyone needs a power amplifier that can deliver 888W RMS into 8 ohms or 1776W into 4 ohms. You could say that no one needs one of these—or two, if you want to listen in stereo. Most household AC systems can't even provide enough current to deliver all that power. But Simaudio does build Moon 888 monoblocks, and people do buy them, whether or not they need an amp that weighs about 250 lb each and costs $118,888/pair.

It was almost seven years ago that Nelson Pass, whose talks and exhibits I'd covered at many a Bay Area Burning Amp DIY event and audio show, surprised me with a loan of two Pass Laboratories' XA 160.5 class-A monoblock amplifiers. Ten months later, after I'd commented that my system had challenged the XA 160.5s in the bass department, he sent me a pair of XA200.5 monos. I connected those bigger babies to Wilson Audio Sophia 3 loudspeakers and some now-discontinued digital components with Nordost Odin 1 interconnects and speaker cables. Then came my way, toward the end of 2016, the XA200.8 monoblocks ($42,000/pair).

Designers of hybrid amplifiers can use solid-state devices in an amp's input stage and tubes in its driver and output stages, as Music Reference's Roger Modjeski did in his RM-200 Mk.II—or they can use tubes in the input and transistors in the output, as Ypsilon Electronics' Demetris Baklavas prefers.

The advantage of solid-state at the input stage can be lower noise. In the RM-200 Mk.II's fully balanced design, carefully matched input devices result in high common-mode rejection and low-noise operation close to the levels achieved with the best input transformers. The RM-200 Mk.II's signal/noise ratio measured a healthy 95.4dB.

"How natural the sound," wrote Jonathan Scull in March 1994, in his Follow-Up on the original Jadis JA 200 monoblock amplifier, which then cost $18,990/pair. "How easy it was to follow the musical line and fall into the music. How deep, controlled, tight, and satisfying the bass. How magnifique the midrange—the traditional strength of the Jadis presentation. How full and satisfying the lower midrange. How open, airy, how right the highs—not at all hard, but very extended and natural. How involving their presentation. How full, how harmonically correct, how wonderfully compelling. How magical."
