I find it more than a little ironic that in 1990 the only two digital-to-analog converters to employ a new state-of-the-art DAC also use vacuum tubes. Many in the audio community consider tubes an anachronism, and find it surprising and humorous that they are still used in newly designed audio products. The fact remains, however, that these two tubed digital processors achieve the best digital playback currently availableand by a wide margin. Moreover, their respective designers' technical savvy and passion for building leading-edge products is reflected in their choice of these superlative and very expensive new DACs. Is it mere coincidence that both designers also chose vacuum tubes to realize their vision of no-compromise digital playback?
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.
Ain't technology grand! That's what I was thinking while driving to work this morning. Sure, the rain was coming down in buckets, but there I was sitting comfortably in a warm car, listening to music while making tracks at 50mph. A long way from horse-and-buggy days.
History teaches us that the full flowering of any social phenomenon takes place after the seeds of its destruction have been sown. That tourist magnet, London's Buckingham Palace, for example, was built decades after the English Revolution and the Restoration had redefined the role of the British monarchy as being merely titular, and made the elected Parliament the real seat of power.
During an Audio Engineering Society meeting where a former colleague of mine was giving an arcane technical discussion of the optical considerations of data retrieval from a Compact Disc, a longtime AES member whispered to me: "What happened to the good old days of AES meetings when we talked about things like tape bias and saturation?"
Rather a mouthful, the name of this digital decoder is derived from that of the designer, Robert Wadia Moses. The "computer" part of the title relates to the custom digital filter function generated by a set of 32-bit microprocessors: for simplicity's sake, I shall abbreviate the name to "WD1000." A more expensive version, called the '2000, sells for $6995, and carries some additional features and details. The resampling rate is increased to 64x in the '2000, with the additional optical and digital input switching and the main power supplies each contained in separate additional enclosures.
Last December, when Wadia Digital announced that it was releasing an iPod docking cradle that could access the digital signal before it had passed through the player's own D/A converter, many audiopundits were surprised. I was disbelieving, and nearly told Wadia's John Schaffer that he was shining me on. After all, Apple has tiptoed around the whole issue of consumers being able to digitally copy their iTunes files, going so far as to wrap its iTunes Music Store files in digital rights management (DRM) code.
I don't remember where I was when the Berlin Wall came down, and I already don't remember what I was doing when Liz Taylor died. (I suppose I was busy not thinking about Liz Taylor.) But I do remember when USB-based computer audio became a serious medium: That was when Gordon Rankin, of Wavelength Audio, introduced asynchronous data streaming, with his proprietary Streamlength software. After that, things picked up speed.
While my enthusiasm for the long-discontinued Sony PlayStation 1 remains high (see the July 2008 Stereophile), I freely acknowledge that not every high-end audio enthusiast wants a CD player with an injection-molded chassis, a Robot Commando handset, and a remarkable lack of long-term reliability: Yes, the Sony sounds wonderful, but sound isn't everything.
One of the better digital front-ends I've ever heard was demonstrated for me a number of years ago at the house of an audiophile friend: a Weiss Engineering combo of Jason CD transport and Medea digital-to-analog converter. That front-end remains in my mind as one of the only digital systems I've heard that could compete with the very best that vinyl has to offer while still doing what digital does best. In other words, there were warmth and musicality, staggering dynamics, and real silent backgrounds. When, recently, I saw that the Swiss company had come out with a DAC featuring onboard volume control, a headphone amp, and a FireWire input, I knew I had to give it a listen.
Some people believe that high-end audio is mostly fluff whose cost, compared to standard professional studio electronics, is not justifiable. Moreover, they argue, if the music has been piped through any number of studio devices before it gets to your home, you can't expect to get more out of it than the studio devices will pass. Just as the argument is made about the final 6' of power cord, how can one Over-The-Top device make up for the foibles of those that precede it?
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?).
Tone controls? I ripped them out of my Dyna PAS-3! And that was the last time I had tone controls. As a card-carrying audiophile, I wanted just what the engineer had inscribed on the recording, with as little change as possible (read: high fidelity).
We were driving to a friend's house to celebrate her dad's 92nd birthday. Halfway there, a bright yellow, ground-hugging insect pulled in front of my car from across street. "Wow, that's a Lamborghini Countach!" I exclaimed. You don't often see one of those in my neighborhood—or in any neighborhood.
