Yesterday's episode of Sunday Morning on CBS included a segment with Herbie Hancock, whose <i><a href="http://blog.stereophile.com/fredkaplan/101507jazz/">River: The Joni Letters</a></i> won two big prizes at the 50th annual <a href="http://blog.stereophile.com/musicroom/robertbaird/021108/">Grammy Awards</a>: Album of the Year and Best Contemporary Jazz Album.

A study published in the open source science journal <I>PLoS One</I> investigates the neural processes of jazz improvisation. Johns Hopkins neuroscientists put piano players in a fMRI scanner with a special keyboard and asked them to perform different five-finger exercises: play a scale, play a melody, and improvise on either the scale or the melody.

The Dalhquist DQ-10 loudspeaker has not as yet been formally submitted for review. (The designer tells us he is still working on the low end.) We auditioned a pair at the one local dealer we could find who had the DQ-10s on demo, and were immensely impressed. Obviously, Jon Dahlquist is on to something that other speaker designers have been overlooking, for, despite the multiplicity of driver speakers in the system, the DQ-10 sounds like one big speaker. There is no awareness of crossovers or separate drivers (except at the low end, about which more subsequently), and the overall sound has a degree of focus and coherence that is surpassed only by the Quad full-range electrostatic, which don't go as low at the bottom or as far out at the top.

I believe <A HREF="http://www.stereophile.com/interviews/232">Ken Kantor</A> said it first: a couple of years ago, in his September 1990 interview with Robert Harley (Vol.13 No.9), he remarked that "there's no reason why a two-way 6" loudspeaker can't be the equal of almost the best speaker out there from a certain frequency point upward, with the possible exception of dynamic range." When I read those words, they rang true. If you put to one side the need to reproduce low bass frequencies and can accept less-than-live playback levels, a small speaker can be as good as the best, and allow its owner to enjoy the benefits of its size&mdash;visual appeal, ease of placement in the room, and the often excellent imaging afforded by the use of a small front baffle.

The wind rushed hard and cold as I emerged from the Columbus Circle station.

I loved the way the band worked together&#151how each member lifted every other, and how each member excelled during solos&#151but I was most impressed by the locked-in rhythm section, and especially Pedro Martinez on congas. His hands turned into light, racing across the conga heads, speeding away from everything else&#151the stage, the room, the cold night&#151while remaining right on time.

According to the conventional wisdom, companies selling consumer products fall into two categories: those whose sales are "marketing-led" and those whose sales are "product-led." Marketing-led companies tend to sell mature products into a mature market where there are no real differences between competing products&mdash;soap powder, mass-market beer, or cigarettes, for example&mdash;whereas product-led companies tend to sell new technologies, such as personal computers and high-end hi-fi components. In the audio separates market, conventional wisdom would have a hard time categorizing any individual company: no matter which you choose, it would be simplistic to say that it is either product- or marketing-led. No matter how good the product, without good marketing the manufacturer stands little chance of success; a poor product superbly marketed may make a company successful overnight, but that success will have hit the end stops by the following night.
