I was setting up for some musical demonstrations I was to present for a Music Matters evening at the ListenUp! store in Boulder, Colorado, in May 2011. For these events, an audio store invites manufacturers (and the occasional journalist) to demonstrate to local audiophiles the musical benefits of high-end audio playback. In Boulder, I was to share the store's big listening room with Dave Nauber, president of Classé Audio, who had set up a system with B&W Diamond 802 speakers, a Classé stereo amplifier, and a preproduction sample of Classé's new CP-800 preamplifier ($5000), all hooked up with AudioQuest cable. I unpacked my MacBook, with which I was going to play the high-resolution master files of some of my Stereophile recordings, and looked around for a DAC. There wasn't one.

I've heard it all a thousand times before:

Don't have $80,000 to drop on dCS's four-component Scarlatti SACD stack that I reviewed in August 2009, or $17,999 for their Puccini SACD/CD player that John Atkinson raved about in December 2009? Even if you do, the new Debussy D/A processor ($10,999) might be a better fit for your 21st-century audio system. Sure, you don't get an SACD transport—or any kind of disc play, for that matter—but the odds today are that you already have a player you like that's got an S/PDIF output that can feed the Debussy.

Things are changing rapidly in the world of professional digital audio. After a decade of stability, with slow but steady improvement in the quality of 16-bit, 44.1kHz audio, the cry among audio engineers is now "24/96!"—meaning 24-bit data sampled at 96kHz. Not coincidentally, DVD offers audiophiles a medium with the potential for playing back music encoded at this new mastering standard.

It's now 10 years since the launch of the two high-resolution audio disc formats, SACD and DVD-Audio. Yet, perhaps partly because both were hobbled in various ways to please the record industry, perhaps partly because too many supposed hi-rez releases sounded no better than CD, and perhaps partly because record retailers weren't sure how to display the formats to their best advantage, neither took off in any substantive way. DVD-A disappeared, and SACD survived only as a niche format for high-quality classical releases in both two- and multichannel forms. As we got deeper into the same decade, digital technology, despite various sparks and flashes, went into the doldrums. Mainstream digital technology was increasingly concerned with squashing the music into fewer and more portable bits, not with increased sound quality. Even the concept of "CD sound quality" began to seem an unattainable goal, as MP3 files became the dominant music carrier.

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."

Is anyone in this economy shopping for a four-box, rack-swallowing, two-channel SACD/CD player contending for the state of the art and costing $79,996? dCS is betting that its Scarlatti will attract a small crowd of those wealthy music enthusiasts who, in any economy, reliably pony up for the best. For the rest of us, the Scarlatti will be a spectator sport.

Giuseppe Verdi gave the world more than two dozen operas, some good sacred music, and one string quartet. He also provided the young Arturo Toscanini with one of his first big breaks—conducting the singing of "Va pensiero" at his burial procession—and gave the flagship consumer product from England's dCS Ltd. its name. That the latter two gestures were posthumous and unwitting does nothing to diminish their poetry.

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?"

Five years after the launch of the audiophile's dream medium, Super Audio CD, the format remains stalled in the market.

More than a decade ago, Data Conversion Systems, aka dCS, released the Elgar Plus DAC, Purcell upsampler, and Verdi SACD/CD transport, for a total price of $34,000. In 2009 came the Scarlatti—a stack of four components for $80,000, also available individually (see my August 2009 review). The latest variation on the English company's theme are the four Vivaldi components, launched at the end of 2012 for a total price of $108,496.

A decade or two ago, I stumbled on a surprising demo room at an audio show. I don't recall most of the equipment, but I do remember a pair of Paradigm Studio 20 speakers at one end, their crossover entrails dangling free, connected to the rest of the system by a multiplicity of wires. At the other end, among the usual electronics, was a PC whose screen was a crazy quilt of graphs and menus that constantly twinkled in response to the ministrations of DEQX's Kim Ryrie. He seemed totally absorbed, but looked up and proudly offered to show me what he was doing. When I told him that I was familiar with the Paradigms, he played some music that sounded just fine. Then he clicked his mouse. The sound was transformed from the familiar to the fabulous. I was dumbfounded. "What have you done?"

Most reviews are straightforward. One preamplifier or power amplifier replaces another. DACs are swapped out. A new pair of speakers takes up residence in the listening room.

But some products demand a complete revision of a system's architecture. Such was the case with Devialet's D-Premier ($15,995). Not only is this French product an integrated amplifier, with phono and line analog inputs; it has digital inputs and an internal D/A section.

In more than 37 years of working at audio magazines, I have never reviewed an Electrocompaniet product. With this review of the company's ECD 2 digital/analog processor, which costs a dollar short of $3100, that streak of inattention has come to an end.

If an audiophile visiting an audio show in 1991 were to have been transported two decades into the future, at first he would not be aware of any difference: A two-channel system would be playing in a hotel room. But on closer inspection, he would notice that the CD player, the ubiquitous source 20 years ago, would be conspicuous by its absence. Yes, there might be a turntable—"Good to see that people are playing LPs in the future," he would think—but why is there a PC in the room?
