Well into dCS managing director Mike Story's attempted explanation of upsampling, there came an epic moment when the ever-expanding universe of his thoughts—which we had been following to new heights of digital enlightenment—broke free of our collective grip, snapped back on itself, and caused a conceptual implosion of nearly cataclysmic proportions. The blank, spent expressions on the faces of the journalists gathered in the small attic-like meeting room at dCS's Great Chesterford (UK) facility all seemed to say, "What the hell was that? Was it just me, or did you feel that too?"
Back in 1984, when I still had all my hair and began listening to digital audio (wait a minute...), I was disappointed with the compact disc. Most of that disappointment came from the format's musical performance, which was poor, but a portion of my dismay came from realizing that my days as a hands-on hobbyist were numbered: I was used to selecting and setting up my own turntable, tonearm, and cartridge, but a CD player defied such involvement. Plugging it in and playing it were all that I or most anyone else could do.
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.
Some people believe that high-end audio is mostly fluff whose cost, compared to standard professional studio electronics, is not justifiable. Moreover, they argue, if the music has been piped through any number of studio devices before it gets to your home, you can't expect to get more out of it than the studio devices will pass. Just as the argument is made about the final 6' of power cord, how can one Over-The-Top device make up for the foibles of those that precede it?
Computers and vacuum tubes go together like Trent Lott and flyaway hair, right? The last time filaments glowed in computers was during the 1960s, when a computer was a building. I remember laughing at the ponytailed computer-science dweebs back then, who spent their college days playing nursemaid to a football field's worth of electronics capable of little more than adding two plus two. Chained to a computer half the day, as most of us now are, guess who had the last laugh?
Such is the pace of development in digital technology these days that it is hard not to become convinced that digital playback is a solved problem. The measured performance aberrations are so low in absolute level—and, more important, so low compared with the typical threshold of human hearing—that it is difficult to see why digital components should sound different from one another.
The Boulder 1012's is a line-level preamplifier and DAC in one box. Its design and build qualities are icons to elegant engineering know-how. No screws show on the rectangular box of large but not massive proportions, for example, which is all done up in matte aluminum and set off with a few highly polished stainless-steel buttons. The chassis construction uses tongue-and-groove techniques. The sides of the 1012 benefit from styling cues found on Boulder's newer amplifiers. As you can see from the photograph, the look is both elegant and hi-tech in a way very few other manufacturers manage.
What's it take to compete on the bleeding edge of digital? Foresight, commitment of resources, and lots of money. Of course, it's all fundamentally about money, so we shouldn't be surprised that the audiophile's emotional needs aren't paid much respect by the large international manufacturing and marketing concerns stalking the earth today. Megaglom vs Cockroachacus. [Sigh] Where are those pesky miniature princess twins when you need 'em?
At the Consumer Electronics show in Las Vegas in January 1999, Mark Schifter, erstwhile president of Audio Alchemy, was handing out a press release announcing what seemed like a groundbreaking product from his new company, Perpetual Technologies. The product was the P-1A, a digital-to-digital processor that would do resolution enhancement, loudspeaker correction (amplitude and phase), and room correction—all for less than $1k. It sounded too good to be true.
The dCS Purcell is named after Henry Purcell, the English composer, organist, bass, countertenor who was born in 1659 and died in, alas, 1695. It's a digital/digital converter intended for consumer use, as opposed to the less elegantly packaged pro-audio version, the dCS 972, that I reviewed in February 1999. Both devices increase the sample rate and/or word length of the output from linear PCM digital audio sources like CD or DVD up to a maximum sample rate of 192kHz and a word length of 24 bits. According to the extensive documentation, this is achieved by "using extremely powerful and accurate digital interpolation filters, which yield an output signal having negligible levels of distortion."
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.
Unlike the imposing mbl and Burmester DACs that I review elsewhere in this issue, the Mark Levinson No.360 is New England conservative in appearance. Its operation was simple to master despite the sophistication and flexibility on tap. Flanked by Fasolt and Fafner, the Levinson No.360 seemed as amiable as Freia.
The Mark Levinson No.30 has enjoyed a continuing residence in Class A of Stereophile's "Recommended Components" listing since it was reviewed in our February 1992 issue (Vol.15 No.2). Madrigal includes the No.30 in its "Reference" series, by which they mean that the unit will not become obsolete. Thus, when new technology became available, the No.30.5 update was introduced, consisting of a single digital-receiver printed circuit board to replace the original's three boards, and a new digital-filtering board. This revision was favorably reviewed by Stereophile in October 1994 (Vol.17 No.10).
