Don't get the wrong idea. I don't watch trash TV. I am not interested in the doings of people who are famous merely for being famous. I was probably the last to realize that Paris Hilton was not the name of a French hotel. But the kitchen TV just happened be tuned to Channel 4 when I switched it on while I was preparing dinner. No, I do not watch NBC's Extra, but as I was reaching for the remote I was stopped in my tracks by what I saw. The show was doing a segment on the new L.A. home of Jessica Aguilera, or Christina Simpson, or . . . well, it doesn't matter. What does matter was the host's mention of all the cool stuff the bimbette had had installed in her new pied-à-terre: "...and a Sonos audio system, of course."

Computers and vacuum tubes go together like Trent Lott and flyaway hair, right? The last time filaments glowed in computers was during the 1960s, when a computer was a building. I remember laughing at the ponytailed computer-science dweebs back then, who spent their college days playing nursemaid to a football field's worth of electronics capable of little more than adding two plus two. Chained to a computer half the day, as most of us now are, guess who had the last laugh?

"Two years ago I discovered my latest guilty pleasure: Internet radio. As long as it's 192k or higher. My whole buying/download cycle had been reduced. The pleasure and savings have increased. If they succeed in killing Net radio, I'm done with the hobby."—Reader Peter DeBoer, in response to a recent Stereophile online poll.

The mind of man, when he gives the spur and bridle to his thoughts, doth never stop, but naturally sallies out into both extremes of high and low.—Jonathan Swift

I think any newish company launching yet another expensive (ie, anything over $2000) digital-to-analog converter on the roiling waters of the audiophile marketplace needs at least two things: a truly great product, and a good story to tell. I think Bricasti Design Ltd., of Medford, Massachusetts, has both.

I've been reading a fascinating book, Leonard Shlain's The Alphabet Versus the Goddess: The Conflict Between Word and Image (New York: Viking, 1998). Shlain's thesis is that the invention of the alphabet was the cause of immense changes in primitive society, upsetting previously widespread norms of gender equality and horizontal (rather than hierarchical) social relations in general.

Were it my place to hand out awards for "The Most Forthright People in Audio," Michael Grace of Grace Design would be at the top of the list. Years ago, after I'd given stellar recommendations of Grace's 901 and m902 headphone-amplifier-DAC-line-stage models, I asked Grace if I could audition his full-rack–size, more fully featured m904 Stereo Monitor Controller. He told me that he didn't think that was necessary, because the m904's sound was extremely similar to the sound of the smaller m902—it just had a different feature set, and he believed that the additional features were not things that Stereophile readers were likely to need. That is the only case I can recall of a manufacturer's declining an offer of additional coverage in Stereophile.

As an equipment reviewer, I find it helpful to talk to audiophiles and music lovers about their systems and upgrade plans. Fortunately, Stereophile's computer supplier and troubleshooter, Michael Mandel, also happens to be an avid audiophile. I say "fortunately" because I rarely get a chance to talk to people who put down their hard-earned money for hi-fi components. Instead, I usually converse with equipment designers, technicians, and marketing types, hardly people who reflect the buying public. It is thus a valuable education to get feedback from real-world consumers to find out what kind of products they want, their priorities, and how much they're willing to spend for certain levels of performance. They have a view distinctly different from that of the often jaded reviewer who is used to enjoying the best (albeit temporarily) without agonizing over its cost.

We audiophiles are ever hopeful that, however satisfying our present equipment and setup, we can achieve even greater enjoyment with a tweak or an upgrade. And we never stop: It was only 16 years (and three turntables) ago that I bought what I declared would be my last turntable, and there's no doubt that this "dead" format has improved substantially since then. Now, even as we make another (but less paradigm-shifting) format transition, from CD to SACD and DVD-Audio, new two-channel DACs continue to appear that show us how far we still are from wresting all the music from the original "Red Book" 16-bit CD format. I reviewed the wonderful Weiss Medea DAC in February 2003, and there are still on my auditioning rack are two more Swiss DACs that might redefine the category: the Orpheus 1 and the Nagra DAP.

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 available—and 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.
