The Anima is a two-way loudspeaker from Canalis Audio, a new enterprise of longtime importer Immedia, of Berkeley, California. Canalis is thereby related to Spiral Groove, and Canalis speakers bear the Spiral Groove logo on their terminal plates. Spiral Groove, founded in 2005, makes turntables; their SG2 ($15,000) was favorably reviewed by Brian Damkroger in the June 2010 issue. Canalis makes at present four models of loudspeakers, all designed in collaboration with noted engineer Joachim Gerhard, formerly of Germany's Audio Physic. All Spiral Groove and Canalis products are made in the US.

Cardas Audio, one of the longest-established boutique audio-cable and accessories innovators, has brought George Cardas' frequency-sweep system-enhancement tweak, previously available on LP for more than 25 years from Cardas Audio and on CD from Ayre Acoustics, into the world of smartphone applications with the "Clarifier" app, available from iTunes' App Store for 99 cents. The app is for the iPhone (and iPod Touch) only; we don't know if an Android version is planned.

I certainly am no stranger to the idea that a "student" orchestra can turn in a performance undeniably superior to those offered by many "professional" orchestras. After all, my favorite commercial recording of Mahler's Symphony 6 is by the orchestra of The Manhattan School of Music, conducted by Glenn Cortese.

But what a special treat it was to hear Daniel Barenboim conduct the orchestra he founded with Edward Said in Weimar in 1999, the West-Eastern Divan Orchestra, in a program of Beethoven's Second and Third ("Eroica") Symphonies at Providence's Veterans Memorial Auditorium on January 26. The concert was presented by the Cogut Center for the Humanities at Brown University. The communication between the conductor and the orchestra members, who obviously revere him, was a wonder to behold. Further, when the carefully-nurtured dynamics finally opened all the way up, the near-stunning sound was a rapturous feast of tactile tonal richness.

My advice: If you live in Big Apple-Land, do whatever it takes to hear Maestro Barenboim leading his young charges in all the Beethoven Symphonies at Carnegie Hall, January 30 to February 3.

There's an old Russian folktale about a farmer who goes to a fair. He buys a bread roll from a vendor. He eats it, but he's still hungry. So he buys and eats another roll, and then another. Still hungry. Next, he buys a donut from a different vendor. At last, he's no longer hungry. The farmer then says to himself, "I wasted the money I spent on the rolls—I should have just bought the donut first!"

Otto von Bismarck (1815–1898), the Prime Minister of Prussia who brought about the unification of Germany, was not a nice man. But he was no dummy, either. One of his most prophetic remarks was in response to a journalist's question about what Bismarck thought to be the single most decisive factor in modern history: "The fact that the North Americans speak English."

The companion loudspeaker to Denon's RCD-CX1 SACD/CD receiver is the SC-CX303 ($1200/pair). The SC-CX303 is a ported two-way with a 1" soft-dome tweeter and a 5" carbon-fiber–cone woofer. Denon claims a sensitivity of 86dB and an impedance of 6 ohms. Instead of a formal frequency response, Denon instead gives an unreferenced figure for frequency extension that, at 35Hz–60kHz, is neither helpful nor credible.

Direct Acoustics is a loudspeaker company in Weston, Massachusetts, that sells, by mail-order only, just one product: the two-way, floorstanding Silent Speaker II ($748/pair).

Its seemingly paradoxical name refers not to any inability of the Silent to create sound, but rather is intended by its maker to indicate two aspects of its performance. First is the ability of the loudspeaker boxes to "disappear" in the sense of not being readily apparent as sound sources. Well, okay, everyone wants that. The other intended sense of Silent is that the woofer and its loading arrangement were designed to minimize stray noises created by the woofer's excursion, or by the movements of air within, or in and out of, its vent or port.

There is much to admire and to enjoy in this idiosyncratically charming hybrid loudspeaker. Eminent Technology has been around for about 25 years. Founder Bruce Thigpen was a pioneer in air-bearing technology, and ET's first product was a well-regarded air-bearing tonearm. The company later developed and was awarded patents for its Linear Field Transducers (LFTs): push-pull loudspeaker panels that operate on the magnetic rather than the electrostatic principle. Arraying magnets both front and rear of the plastic-membrane diaphragm eliminates a problem inherent in many planar-magnetic designs: as excursion increases, the magnetic restorative force diminishes. As can be expected, this technology is not efficient at reproducing bass, so most such speakers have been hybrids.
