"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?
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.
My quandary on receiving for review the Linn Majik DS-I: What, precisely, is it supposed to do? Does the Majik DS-I contain a hard disk and music-ripping software, so I can use it to store all the music in my CD collection? Does it have a graphical user interface (GUI) that at least matches the one provided by the endearingly free Apple iTunes? Does it include a DAC that allows it to play the music files I've already put on my computer?
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.
Art Dudley and others have covered the first products released by HRT, and now the company has added to its product line a Pro version of its Music Streamer, which sports balanced circuit design from tip to tail.
Housed in the same simple, functional, six-sided case of extruded aluminum as HRT's other products, the Pro is painted a bright blue to distinguish it from the Music Streamer II (red) and Music Streamer II+ (gray). At 5.6" it is also a tad longer than the others, and includes a single B-type USB 1.1 jack centered on one end, and two small, fully balanced TiniQ output jacks on the other. More about these special mini sockets later.
In November 2009, I took part in an intriguing comparison between live and recorded sound. I first recorded a live piano recital in 24-bit/96kHz digital, then allowed the audience to immediately hear the recording in the same room. (See my February 2010 thoughts on the comparison here.) For playback, I used two of the mono Esoteric D-01VU D/A converters locked to the ultra-high-precision Esoteric G-0Rb "atomic" master clock. I was very impressed by the sound of this cost-no-object digital system, so when I visited the Japanese company's room at the 2010 Consumer Electronics Show and saw their new, relatively affordable D-07 D/A processor ($4800), I asked for a review sample.
There's home cooking on one side of the hedge and fast food on the other, and the world moves farther from the former and nearer to the latter with each passing day. So it goes in domestic audio, where virtually every new milestone of the past quarter-century has pointed far more toward convenience than toward quality.
Depressed? Don't be. Those of us in the perfectionist community have a history of dealing with such things, howsoever slowly and inefficiently. (footnote 1). We're getting better at it, too, year by year. An example: Chord Electronics, of sunny southern England, has now brought to market their Chordette Gem D/A converter ($799) which they offer as an affordable means of getting perfectionist-quality sound from computer-music files.
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 transportor any kind of disc play, for that matterbut the odds today are that you already have a player you like that's got an S/PDIF output that can feed the Debussy.
The weekly Vote! Page is one of the most popular features of the Stereophile website, and the August 22 question, "Should Stereophile review more or fewer computer-audio products?", generated a record number of responses. No less than 88% of those responding asked for more coverage of products that allow a computer to be a legitimate source of music in a high-end context. Just 7% of readers wanted less coverage.
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?
YBA Design's new WD202 D/A processor and headphone amplifier showed up while I was turning the pages of Don and Jeff Breithaupt's Precious and Few: Pop Music of the Early '70s, recommended by John Marks in his October 2009 "Fifth Element" column. Each page drips with great examples of why the 1970s often wind up on the wrong end of the culture stick (the Osmonds, anyone? Terry Jacks?).
As someone who wrestled endlessly with the nine-pin serial ports and the RS-232 protocol with which early PCs came fitted (footnote 1), I welcomed the Universal Serial Bus (USB) interface when I first encountered it a decade ago, on the original Apple iMac. Plug it in. Don't worry. Be happy. The computer peripherals work as they should, which was often not the case with RS-232. It was a given, therefore, that the then-new USB port would be seen as a natural means of exporting audio data from a PC (footnote 2), but the first generation of USB-connected audio devices offered disappointing performance.
In an industry whose newest products are often as discouragingly unaffordable as they are short of the sonic mark, the Naim Audio Uniti ($3795) stands out. In a single reasonably sized box, the Uniti combines the guts of Naim's Nait 5i integrated amplifier and CD5i CD player with various additional sources: an FM/DAB tuner, and interfaces for an iPod, a USB memory stick, an iRadio, and a UPnP-compatible connected computer or serverall for the price of a very good television set.
In February 2009, I reviewed Bryston Ltd.'s first CD player, the $2695 BCD-1, and was very impressed by what I heard. The BDA-1 ($1995) is the Canadian company's first standalone DAC. It's slim, only 2.75" high, with the engraved company name, model number, and infrared sensor grouped at the extreme left of a front panel of polished aluminum. Farther to the right are two columns of four LEDs each that comprise the sample-rate indicator, which identifies the selected input's signal frequency and whether the BDA-1 has locked to it. Closer to the center is the Upsample control, which governs the conversion of the incoming digital signal synchronously to 192kHz or 176.4kHz. The Upsample LED turns green for 192kHz, red for 176.4kHz. Digital sources are selected by pressing one of eight pushbuttons just right of center: two TosLink, four S/PDIF (coaxial), one AES/EBU XLR, and one USB 1.1, the last accepting only signals with sample rates at or below 48kHz. An LED above each pushbutton lights green for an incoming PCM datastreams and red for other types, including multichannel Dolby Digital streams.
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.
