Am I the only one who values content and convenience over sound quality?

There. I've said it. I am not an audiophile; ie, someone who's in love with recorded sound for its own sake. The search for ideal sound can leave a person burned out and broke.

Since the first digital processor on the market using UltraAnalog DACs appeared (the $12,000 Stax DAC-X1t, reviewed in August 1990, Vol.13 No.8), there has been a proliferation of good-sounding processors using this extraordinary—and expensive—part. Among these are the Audio Research DAC1, Audio Research DAC1-20, VTL Reference D/A, and the groundbreaking Mark Levinson No.30 reviewed last month.

Erick Lichte's review of Benchmark's DAC2 HGC D/A converter in this issue gave me an ideal opportunity to spill some ink on the company's ADC1 USB A/D converter. The ADC1 is housed in the same small case as the DAC (one rack unit high, half the rack unit width), and is offered with a black front panel with rack ears, or a silver aluminum panel without ears, either for $1795.

I was alerted to the new VEGA D/A processor from Chinese manufacturer AURALiC by Michael Lavorgna's rave review for our sister site AudioStream.com in April 2013: "Everything I played through the Auralic Vega was equally wow-inducing. Everything. . . . Music I've heard hundreds of times was presented with a crisp, clean, and delicate clarity that was simply uncanny and made things old, new again. . . . Its ability to turn music reproduction into an engaging and thrilling musical experience is simply stunning."

I totally called this one.

In 2007, I spent time with Bel Canto Design's e.One DAC3 D/A processor. In his review of the DAC3 in the November 2007 issue, John Atkinson quoted my comparison of it with the Benchmark DAC1, which I called "the Swiss army knife of audio" and "one of the only future-proof source components you can buy these days."

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.

In my November 2013 column, I looked at the NuForce AVP-18 multichannel preamplifier-processor ($1095) and the exaSound e28 multichannel DAC ($3299), each of which offers fresh options in its category that break with the predictability of mainstream products. That predictability is the result of market analysis that supposedly tells manufacturers which features users want most. However, it's just as true that users can buy and choose among only those components and features already offered. Many of us are more peculiar in our demands—what's generally offered doesn't always fit our needs. This month, I look at an unusual pre-pro and a multichannel digital equalizer at opposite ends of the price spectrum.

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.

Now entering its fourth decade, the Compact Disc player seems to have reached a stage of maturity where the best models within a given price range will sound pretty much alike. The technology of the Compact Disc itself is set, its possibilities and limitations are well understood; and the designers of CD players who figure out how to stretch the former and finesse the latter wind up at about the same sonic place (again, for the same price), even if they've taken different routes to get there.

Tubes?

In a CD player?

Century-old technology embedded in a modern digital design?

I realize that Aesthetix's Saturn Romulus is not the first disc player or D/A processor with tubes, nor will it be the last—but does combining these technologies even make sense? Are audiophiles working at cross purposes to themselves, looking for modern perfection but preferring a little old-school sweetening here and there?

John Stronczer, Bel Canto Design's technical spark plug, meets my definition of an electronics renaissance man, ranging as he does from designing single-ended amps that glow in the dark (the Orfeo) to digital processors (the Aida). Actually, digital circuitry is one of John's specialties, dating back to his days at Honeywell.

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.

Late last year came an epic audiophile moment: I slapped a final length of tape on the box of the awesome-sounding MSB Diamond DAC (Stereophile, October 2012), in final preparation for its trek to John Atkinson's testing lab, in Brooklyn. Next up was the Bifrost DAC from Schiit Audio. I popped it into my system, where, moments before, the MSB had held court.

From $43,325 to $449. Yowseh!!—the MSB costs almost 100 times as much as the Schiit! Was this even fair?

For the audiophile modernist, a DAC with volume control is the straightest path between the music server or network stream and your amp and speakers. If you've fully embraced networked audio, there's no need for fussy preamps with their analog inputs, analog volume controls, and [gasp!] phono stages. Find a digital source, a DAC with volume, and go.

For the past few years, one of Stereophile's go-to recommendations for affordable high-performance D/A processors has been the M1DAC from British company Musical Fidelity. The M1DAC was enthusiastically reviewed by Sam Tellig in March 2011, and I wrote about the most recent version in January 2013. "Purity of tone was exceptional," decided Mr. T., which I found to be accompanied by superb measured performance, all at a very reasonable price: $749.
