As Wes Phillips recently reported on this website, CD sales are down and legal downloads of audio files are up. Stereophile has been criticized more than once for not paying enough attention to the subjects of MP3 and other compressed file formats, such as AAC, and for offering no guidance at all to readers about how to get the best sound quality from compressed downloads.
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.
"Physical discs seem so 20th century!" That's how I ended my eNewsletter review of the Logitech (then Slim Devices) Squeezebox WiFi music server in April 2006, and it seems that increasing numbers of Stereophile readers agree with me. In our website poll of January 5, 2008, we asked, "Are you ready for an audiophile music server?" The response to that question was the highest we have experienced: 32% of respondents already listen to music via their computer networks, many using home-brewed solutions, and 44% intend to. We've published a lot of material on this subject in the last five years, and it seemed a good idea to sum it up in this article.
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.
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.
How do I get myself into these things? Knowing that I use a Musical Fidelity X-DACV3 D/A processor in my office system and had just auditioned the Bel Canto e.One DAC3 that he'd reviewed in November, John Atkinson asked me to give Musical Fidelity's X-DACV8 a try. I say "asked," but the man does authorize my paychecks, so I acceded, knowing I was painting a giant bull's-eye on my back.
Even Mikey Fremer is surprised at vinyl's current popularity. Some pundits postulate that eventually CDs will die out, and we'll be faced with the choice of LPs or downloads. (I hope not. I'm just getting used to CDs.) With abundant sources of new pop releases and a wide range of reissues on vinyl, and a variety of used LPs, every audiophile should own a turntable. And with the availability of affordable turntables such as the Pro-Ject Debut III, which I reviewed in the February 2010 Stereophile, the cost of entry to VinylLand is not very dear. The problem is that so few entry-level integrated amplifiers and receivers available today include phono stages. (The Marantz PM5003, which I reviewed in the January 2010 issue, is a notable exception.)
Oh boy, another new DAC review. Some folks think DACs, once you get past the features, all sound pretty much the same. I mean, it's just digital. Well, they're right. Pretty much. Just as two new cars of a particular make, model, color, and options package both look the same, sitting there on the lot.
But if you discover a ding in the door of one of them, where most folks still see only a new car, you now see the ding. It might have been there all along, undetected the first few times you walked around the carmaybe your buddy even had to point it out to you. It's insignificant in the scheme of all that a new car is, but once you've seen it, you always see it. Now you can easily tell the two cars apart, and we both know which one you'll drive home.
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 flexibilitywithout resorting to a pair of tinny, uncomfortable earbuds?
As long as you're spinning an LP for your listening pleasure, and if digitizing it at a resolution of 24-bit/192kHz is transparent to the analog source, why not record and store the LP on your computer at that high sampling rate for future convenient playback via iTunes or for iPod use, or for burning to CD-R? And, while you're at it, why not record the LP unequalized and apply the RIAA curve in the digital domain, where you're not dependent on capacitors and resistors that are imprecise to begin with, and can drift over time? With no drift of phase or value, the virtual filter's results should be better than with any analog filter. And in the digital domain, you can program in any curve known, and select it at the click of a mouse. Aside from the sweat equity invested in programming it in the first place, it wouldn't add a penny to the program's cost.
"We like to make things," Roy Gandy, Rega's founder and owner, once told me. "It's what we do." Or maybe it was Rega's chairman and chief engineering honcho, Terry Bateman. Rega products are designed and manufactured in the south of England. So far as I know, no one at the Rega facility, on the Temple Farm Industrial Estate, has committed suicide; the same cannot be said of workers at the factory in China where iPods are made. Al Gore is on the board of Apple. Al, what do you think?
The dual subwoofers were bumping and our pant legs were flapping. Only moments before, we'd been treated to a polite viola da gamba. Not now. Resolution Audio's designer, Jeff Kalt, had brought only two discs with him to ensure that his company's Cantata Music Center was functioning properly in my system: Jordi Savall and Hespérion XXI's Altre Follie, 15001750 (CD, Alia Vox 9844), and Tool's 10,000 Days (CD, Tool Dissectional/Volcano 81991). After changing a few things around with the chamber music, we'd advanced to the hard rock of Tool.
When I read John Atkinson's reviews of the Digital Audio Labs CardDeluxe (Vol.23 No.9) and RME Digi96/8 Pro (Vol.23 No.11 and Vol.24 No.1), I realized that soundcard technology had matured far faster than I had been aware. For about the price of a mainstream CD player, anyone with a reasonably powerful computer could add multitrack digital recording technology to his bag of tricks.
