My quandary on receiving for review the Linn Majik DS-I: What, precisely, is it supposed to do? Does the Majik DS-I contain a hard disk and music-ripping software, so I can use it to store all the music in my CD collection? Does it have a graphical user interface (GUI) that at least matches the one provided by the endearingly free Apple iTunes? Does it include a DAC that allows it to play the music files I've already put on my computer?

My first trip to a Consumer Electronics Show, in January 2010, was an eye-opener. Not only had I never before seen the phony glories of Las Vegas, it was the first time I'd been to a high-end audio show. Between the offerings on the top floors of the Venetian and T.H.E. Show at the Flamingo, I met some great people and heard some wonderful new products. One of those people was distributor Kevin Deal, and one of those new products was from Mystère. Though I was familiar with the PrimaLuna line that Deal also distributes, Mystère was, well, a mystery. However, after a listen to the Mystère pa21 power amplifier making a pair of MartinLogan speakers sing, and after noting the reasonable prices for some of Mystère's beautifully designed and built amps, I put Mystère in my review queue.

In my review of Krell's FBI integrated amplifier in the July 2007 issue, I noted that $16,500 (it now costs $18,000) seemed an astonishing chunk of change to spend on a product category generally associated with "budget" gear. Now, the 2011 edition of the Stereophile Buyer's Guide lists no fewer than 19 companies selling integrated amps for five figures—one goes for $100,000!—which perhaps suggests that economic slumps prod even the well-heeled to alter their habits. There are, after all, advantages to cramming a preamplifier and a power amplifier into a single box: you need one less pair of interconnects, one less power socket, one less cabinet shelf. And if the integrated contains state-of-the-art parts, elegant circuitry, and a hefty power supply, what's the problem?

And so we have Simaudio Ltd., the veteran Canadian high-end electronics firm, leaping into this realm after 30 years of business with the Moon 700i, priced at $12,000—only two-thirds the price of the Krell, but aimed at the same downsizing but still toney demographic.

Ten thousand hours. According to Malcolm Gladwell, in his book Outliers: The Story of Success, it takes 10,000 hours of practice to become truly exceptional in your field. For any endeavor, Gladwell contends, what will get you to Carnegie Hall isn't inborn talent but practice, practice, practice.

As with so many other things, from cell phones to soy milk, the idea of a portable MP3 player was something I at first disdained, only to later embrace with the fervor of any reformed sinner. But not so the idea of a high-fidelity iPod dock: Given that I now carry around several hundred high-resolution AIFF files on my own Apple iPod Touch, the usefulness of a compatible transport seemed obvious from the start. Look at it this way: In 1970, whenever I bought a music recording, I could enjoy it on any player, in any room in the house. In 2010, why shouldn't I enjoy at least that degree of convenience and flexibility—without resorting to a pair of tinny, uncomfortable earbuds?

In sixth grade, I was given a Victorinox Swiss Army knife. I loved it. An avid camper and erstwhile Boy Scout, I was amazed at how many things I could do with this well-made, pocket-size wonder. I used its tweezers to remove splinters and ticks, its scissors to cut thread, its can opener to prize open tins of baked beans, and its knife blade to whittle, occasionally cut myself, and generally wreak teenage mayhem.

As I grew older, I discovered that using specialized tools for a given job was generally easier, faster, and more pleasurable than using my Swiss Army knife's utilities. Though I could cut a tent's ground cloth with my knife's scissors, a plain-Jane pair of Fiskars worked much better, an OXO can opener got me into those baked beans much faster than my Victorinox could, and even my Swiss Army knife blade didn't stay as sharp or fit in my hand as well as a simple Buck knife. Still, there was no doubt that my Swiss Army knife was a great tool and a good value, even if it was never the best tool for a specific task. To put it another way: The value of my Swiss Army knife was broad but shallow, while the value of something like my OXO can opener was narrow but deep.

I'm a basically a tube guy, but I've never warmed up to most lower-powered integrated tube amps. Although I quite enjoyed the time I spent with the Cayin A-50T, which I reviewed in the March 2008 issue of Stereophile, over the years I've typically found I'd rather spend time with mid-priced, solid-state integrateds from Creek, Musical Fidelity, or Simaudio than deal with the loss of definition at the frequency extremes that I've heard from many lower-powered tube models. So it was with a bit of trepidation that I approached the VSi60, a 50Wpc integrated amplifier from Audio Research Corporation.

Leben Hi-Fi Stereo Company is a very small company in Amagasaki City, Japan, that hand-builds an exquisite line of vacuum-tube audio electronics. I find it intriguing that Taku Hyodo, founder and main man of Leben, once worked for the comparatively huge Luxman firm. Years back, Luxman went through various corporate owners and spent some time wandering in the desert, before returning to its high-end audio heritage. Whether, as I suspect, Leben was founded during Luxman's years of ownership by car-stereo maker Alpine, or if Hyodo simply wanted to be the captain of his own destiny, I don't know.

An audio/video receiver in Stereophile? Heresy!

Besides my 20th wedding anniversary and the 15th anniversary of Listener magazine's first issue, this year marks the 25th anniversary of Roksan Audio Ltd., easily one of the most innovative design and manufacturing firms in British audio. Before Roksan came upon the scene in 1985, none of us had ever seen a loudspeaker whose tweeter was isolated from its surroundings by a sprung suspension. Or a commercial phono preamplifier designed to fit inside a turntable, just a centimeter away from the tonearm base. And who among us could have guessed that the Linn LP12's hegemony—among flat-earthers, I mean—would be broken by a turntable from outside of Scotland? Yet the Roksan Darius loudspeaker, Artaxerxes phono stage, and, above all, Xerxes turntable accomplished those things and more, to the genuine surprise of nearly everyone—and to the benefit of our industry at large, as other firms took those ideas and ran with them.

There's a fantastic new two-SACD/CD set of a demonstration-quality live recording of a rather obscure work you really should get to know, not only for its own merits, but also for what I believe is its underappreciated but major influence on music and on popular culture. The piece is by 20th-century composer Arnold Schoenberg, but trust me—it's more than "listenable." It (or, at least, the music on the first disc) is beyond engaging; it is compelling—a revelation, even. The work is Gurrelieder (Songs of Gurre), Gurre being a castle in medieval Denmark that was the setting of a real-life doomed love triangle, the story of which has since loomed large in the moodily brooding artistic consciousness of Danes. The 19th-century Danish poet Jens Peter Jacobsen wrote a collection of poems based on medieval legends, including this one, and a German translation by Robert Franz Arnold provided Schoenberg's dramatic texts.

To celebrate his 30 years with the company, Marantz threw designer Ken Ishiwata a birthday party in the form of an assignment: Design a new, limited-edition integrated amplifier and SACD/CD player bearing his initials. (Only 500 of each will be made worldwide.)

Years ago, when I taught high school choirs, I had many types of kids in my ensembles. Though none exclusively fit the overly stereotypical lineup of kids on Fox TV's Glee, I always managed to have a nice assortment of jocks, preps, goths, motorheads, geeks, wastoids, and dweebs. One of the things that always fascinated me was how the big, tough jocks would turn out to be the most sensitive, emotional singers. It was always a touching moment when an otherwise stoic football star or wrestler would get all misty while singing the final song of the year-end concert. It showed me that the toughest exteriors often hide the creamiest creampuffs.

In an industry whose newest products are often as discouragingly unaffordable as they are short of the sonic mark, the Naim Audio Uniti ($3795) stands out. In a single reasonably sized box, the Uniti combines the guts of Naim's Nait 5i integrated amplifier and CD5i CD player with various additional sources: an FM/DAB tuner, and interfaces for an iPod, a USB memory stick, an iRadio, and a UPnP-compatible connected computer or server—all for the price of a very good television set.

A decade ago, many predicted that amplifiers with switching or class-D1 output stages would come to dominate high-end audio. In a post–Peak Oil world in which the price of energy would always continue to rise, a class-D amplifier's very high efficiency in converting AC from the wall outlet into speaker-driving power would be a killer benefit. Although a conventional push-pull class-B amplifier has a theoretical efficiency of 78.5%, which would seem usefully high, this efficiency is obtained only at the onset of clipping; the need for the output devices to carry a standing bias current reduces that efficiency considerably, typically to around 50%. Class-A amplifiers are even less efficient, with a maximum of 25%; ie, three times as much power is dissipated by the amplifier as waste heat as is used to drive the loudspeaker (see "Sam's Space" in this issue).
