The May 2011 issue of Stereophile is now on newsstands. I’m sorry: I don’t remember anything about the making of this issue. It seems like it happened a million years ago. It must have been traumatic. (I do remember making meatloaf. That was a lot of work, too.) But I can tell you what’s inside this issue.

Let’s take a look:

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.

Audio journalism is an unwitting form of pornography, albeit one that debases the soul with materialism instead of carnalism. It encourages—inadvertently, of course—the objectification of its subject matter, and can lead to Chronic Disappointment Syndrome, as well as a lifelong difficulty in forging healthy relationships with technology.

Those used to be just fun things to say. But now I worry they might be true, if only because thinking, reading, and writing about domestic audio have, of late, brought with them the chalky aftertaste of guilt.

After seeing Ambrose Akinmusire’s quintet at the Jazz Standard in New York City last Sunday night, I realize that, if anything, my recent blog posting sold him short—or fell short, anyway, in describing what makes him so remarkable.

Unlike many of the best young lions of recent years, Akinmusire is not aiming to expand the realm of jazz to include hip-hop, classical, Latin, or whatever. He is steeped in “the jazz tradition” and aims to deepen his stance within it—but his approach doesn’t seem the slightest bit retro. His trumpet tone, as noted earlier, has traces of Clifford Brown and Booker Little; but how he shapes that sound—as a player, a composer-arranger, and an ensemble-leader—is thoroughly distinctive. . .
