Meridian 518 Digital Audio Processor
John Atkinson  |  Jan 01, 1996  |  0 comments
The High End is a tidily ordered world. There are CD players, transports, and processors used to play stereo recordings and drive stereo preamplifiers. There are stereo or mono amplifiers used to drive a pair of speakers. And then there is the British high-end company Meridian, run by one J. Robert Stuart, one of audio's deeper thinkers and a Fellow of the Audio Engineering Society. Meridian does it their way. They put their amplifiers inside their speakers. Heck, Meridian even puts their D/A processors inside their speakers when they can. And two speakers to play back stereo recordings? Meridian believes in re-creating the original soundfield no matter how many speakers and channels it takes to do it right. And they do it sufficiently successfully that their Digital Theatre system, which does all of the above, was one of Stereophile's joint Home Theater products of 1995.

Meridian 808.2/808i.2 Signature Reference CD player/preamplifier
John Atkinson  |  Apr 13, 2009  |  0 comments
It's been a while since I auditioned a Meridian CD player in my system. I had enthusiastically reviewed the English company's groundbreaking Pro-MCD player in early 1986, and over the years had kept up with the progress they were making in digital playback, either through my own reviews or by performing the measurements to accompany reviews by other Stereophile writers. The 508-24 player, reviewed by Wes Phillips in May 1998, was one of the finest digital products of the 1990s, I thought. But when Meridian began promoting surround sound and DVD-Audio at the turn of the century, their goals became somewhat incompatible with my own. Yes, I can appreciate what surround playback can do, but my own musical life is still solidly rooted in Two-Channel Land.

Meridian Audio Prime D/A headphone amplifier
John Atkinson  |  Oct 05, 2014  |  2 comments
A reader recently asked if I preferred listening to loudspeakers or to headphones. There is no easy answer: Although I do most of my music listening through speakers, about 10% of that listening, for various reasons, takes place in the privacy of my headphones. I have also found that, since I purchased the Audeze LCD-X headphones following my review of them last March, I now tend to watch movies on my MacBook Pro, with the soundtrack reproduced by these headphones plugged into an AudioQuest DragonFly or whatever D/A headphone amplifier has been passing through my test lab. So when Meridian's PR person, Sue Toscano, asked me last Christmas if I'd be interested in reviewing the English company's new Prime D/A headphone amplifier ($2000) with its optional Prime Power Supply ($1295), it took me less than a New York minute to say "Yes."

Meridian Audio Ultra DAC D/A processor
John Atkinson  |  Apr 18, 2017  |  9 comments
As I mentioned in my review eight years ago of Meridian Audio's 808.2 Signature Reference CD player, I have long been impressed by the British company's components—in fact, ever since the early 1980s, when I purchased a Meridian 101 preamplifier, followed by my very positive experiences with Meridian's MCD Pro and 208 CD players, 518 digital audio processor, D600 and DSP8000 digital active loudspeakers, and, most recently, the Prime and Explorer D/A headphone amplifiers.

Meridian Explorer USB D/A processor/headphone amplifier

Those of us who groan at the appearance of every new five-figure digital source component in a massively oversized chassis—and who groan in greater torment when the offending manufacturer says his customer base insists on products that are styled and built and priced that way—can take heart: The appearance of such sanely sized and affordable products as the Halide Design DAC HD ($495) and the AudioQuest DragonFly ($249) would suggest that the market has a mind of its own.

Meridian Explorer2 D/A headphone amplifier
Jim Austin  |  May 19, 2016  |  3 comments
I was lying on a mattress on the floor of an empty apartment on Manhattan's Upper West Side. Not as grim as it sounds—it's a nice apartment, and the mattress was new, and had just been delivered—but it was hot (no air-conditioning), and my family and my furniture were still in my condo up in Maine, and I was lonely. I needed some cheering up. Which is how I rationalized the decision to buy an Explorer2, Meridian Audio's tiny, inexpensive ($299) digital-to-analog converter.

Micromega AS-400 D/A integrated amplifier

Blind though I am to the allure of blind testing, I can appreciate some degree of review-sample anonymity: Distinctive products elicit distinctive responses, but a plain black box encourages us to leave our prejudices at the door. It asks of us a certain . . . objectivity.

So it was with the Micromega AS-400 digital source/integrated amplifier ($4495), the anonymity of which was compounded, in my case, by a generous helping of forgetfulness: I suppose I was told, ahead of time, that this was a class-D amplifier, but at some point in time before my first at-home audition I apparently killed the brain cells responsible for remembering that fact. So I was innocent of conscious prejudice when I listened to this elegant cipher of a box and wrote, in my notes: "Dynamic, dramatic, and almost relentlessly exciting with some recordings. Imbued pianos with almost too much dynamism for the room—too much being very good!—but lacked some 'purr' in the die-away. Basically fine and fun. Wish it had a little more color and spatial depth."

Mojo Mystique X SE D/A processor

When I survey the realms of fancy-pants audio, the first thing I notice are cohorts of luxury-brand manufacturers selling pride of ownership with emblematic faceplates. After that, I spot another type of manufacturer, one that mocks the first type and aims its products at a younger, more working-class demographic, seducing potential customers with how much "truth" they are offering for only $15. But sometimes, when I look beyond the full-page ads and big rooms at audio shows, I discover a rogue manufacturer that is peddling a very specific type of listening experience, which they believe is the best. A listening experience only they could have created. I am grateful for manufacturers like this. They make my job more interesting, and I admire them for their courage in betting on their own taste in music reproduction.

I am relating these observations because this month I'm reviewing a digital converter from an off-the-paved-road audio manufacturer named Benjamin Zwickel. He operates a company called Mojo Audio, which is located in Albuquerque, New Mexico.

Moon by Simaudio Evolution 780D D/A processor
Michael Fremer  |  Jul 21, 2016  |  10 comments
Simaudio saw disc-based digital audio in its rear-view mirror at least as far back as 2011, when it introduced the Moon Evolution 650D and 750D—two iterations of what it called a "digital-to-analog converter CD transport." These were actually multiple-input CD players, but Simaudio was evidently so eager to distance itself from the spinning disc that it went with a product category that, in spite of its cumbersome, run-on name, drew a clean line between the disc-reading and signal-processing functions—while bestowing upon the former second-class citizenship.

I am a lucky person. Who gets to be an artist, an aspiring griot, and a Stereophile reporter? Who gets to stay at home in paint-smeared pajamas, draw pictures of teapots and barn owls . . . and then, on top of everything, gets paid to listen to music made by Henryk Szeryng, Eugene Hütz, and Winston Reedy? C'est moi!

I have groovy friends, too: other eccentric artists, scruffy musicians, recording and mastering engineers, beekeepers, authors and editors, art and junk collectors, tube wizards, turntable savants, DJs, Mensa-type amp designers, bat-shit-crazy poet-philosophers, and unrepentant hoarders.

MSB Link DAC III D/A converter

Prelude
I fell in love with the original Link DAC, as was obvious from my review in the January 1999 Stereophile. I said that "the Link redefines entry into high-quality digital sound," as it provided excellent sound and 24-bit/96kHz conversion for the remarkably low price of $349. It is as firmly ensconced in Class C of "Recommended Components" as it is in my weekend system, where it tames the digital signals from my DMX receiver and my trusty old Pioneer PD-7100 CD player.

I have a warm spot in my heart for MSB's approach to product development. They come from a tweaker heritage and still practice the art: MSB will happily install a 24-bit/192kHz upsampler in your CD player, a 5.1-channel input in your DPL amp or receiver, and true 24/96 outputs in your DVD player. Their standalone products, starting with the original Link DAC, are designed from the start to include space for later additions and enhancements.

MSB Technology Analog DAC D/A converter and Analog Power Base power supply
Jon Iverson  |  Mar 28, 2014  |  3 comments
Back in high-end audio's golden days—for the purposes of this story, the mid- to late 1980s—my audio store, Audio Ecstasy, had a service tech named Tom Hewitt. Were he still with us (and I wish he were), Tom would appreciate the radical case design of the MSB Analog DAC. Tom loved not only to fix things, but to see what happened when things were violently stressed. He tested the limits of component construction.

MSB Technology Link D/A converter
Kalman Rubinson  |  Jan 28, 1999  |  0 comments
Recently, we've seen the digital "horsepower" race accelerate with the arrival of digital sources and devices with 24-bit and 96kHz sampling capability. Much of this has been spurred by the 24/96 labels emblazoned on the newer DVD players—and, within the purer confines of the audio community, by high-end DACs with this same ability. Indeed, it's possible that the dCS Elgar DAC, near and dear to John Atkinson's heart and a perennial Class A selection in Stereophile's "Recommended Components," performs so well with standard 16-bit/44.1kHz sources because its wider digital bandwidth permits greater linearity within the more restricted range of regular CDs.
