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.
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.
The audiophile does not pursue music reproduction because it is useful; he pursues it because he delights in it, and he delights in it because it is beautiful. If music were not beautiful it would not be worth knowing, and if music were not worth knowing life would not be worth living.
My apologies for corrupting the well-known statement by French mathematician Jules Henri Poincaré (18541912), in which he described his relationship with science and nature. But substituting audiophile for scientist and music for nature, I feel the sentiment expresses what drives many audiophiles to the extremes for which mere mortals often chide us.
Roy Hall has been Creek Audio's US importer for more than 20 years. Did you know that all Creek gear is now made in China? Just like Cambridge Audio, Quad, and many B&W models. Just like some US speaker brands, for which virtually all parts are made in China but are assembled, it's claimed, in the US. Three cheers for brands like LFD, Rega, Sugden, and Harbethall still made in the UK. For French marques made in France. For Italian products produced in Italy. Etc.
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 demandswhat'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.
The rapidly evolving world of the late 20th century is the source of much stress. Changes in the status quo, whether wrought by social, political, or technological forces, are often accompanied by anxiety brought on by the struggle to assimilate new patterns of thought. New ideas necessitate abandoning or modifying one's old ideas, thus creating conflict (footnote 1). However, these periods of rapid change can also be exciting, allowing one to chart a course of discovery and growth.
The taxonomy of audio products used to be easy. An amp, a preamp, speakers, a disc player or twodone. Now that hard drives, streaming clouds, and computers have entered the scene, unless your world revolves around only an iPod or a disc player, you have choiceslots of choices.
The M1 DAC is by Musical Fidelity. At $699, it's a stunning bargain. Comparing it to $995 for the Digilog in 1989. Meanwhile, the M1 is far more versatile, way better built, and, if memory serves me right, sounds vastly better.
It appears that the way to sell a DAC in 2011 is to almost give it away, in real-dollar terms. Some people pay far more than this for a set of speaker cables, a pair of interconnects, even a power cord. The M1 DAC is a piece of kit that can transform your system. I kid you not.
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.
There's so much uncertainty and confusion surrounding computer audio and high-resolution downloads. Which hi-rez formats will win out? How do you store the downloads you've bought? (Easy. Don't buy them.) How do you access them? Will digital rights management (DRM) cramp your style, or data-storage fees for cloud computing crumple your wallet?
A computer is not optimized for the uninterrupted streaming of audio data. It has rapidly become established wisdom, therefore, that the optimal means of extracting audio data from a computer's USB port is to operate that port in what is called "asynchronous isochronous" mode. This lets the receiving device, such as a digital-to-analog converter (DAC), control the flow of data from the PC. In theory, asynchronous USB operation (not to be confused with the asynchronous sample-rate conversion used in some DACs) reduces jitter to unmeasurable levels, depending on the accuracy of the receiver's fixed-frequency oscillator, which is used to clock the data to the DAC. By contrast, in the alternative and almost ubiquitous USB operating mode, called "adaptive isochronous," while the sample rate of the output data, averaged over a longish period, will indeed be the specified 44.1 or 48kHz, there will be short-term fluctuations, or jitter, due to the oscillator having to change its frequency every millisecond to match the uncertain rate of data flow from the PC.
