The AAD Reference Silver-1 was of below-average sensitivity, at an estimated 84dB(B)/2.83V/m, which, all things being equal, will demand more watts than usual from the partnering amplifier. However, the Silver-1's impedance modulus (fig.1, solid trace) remains high over almost the entire audioband, with a minimum value of 5.4 ohms at 284Hz. And although the electrical phase angle (fig.1, dotted trace) reaches ±45°, this occurs only when the impedance is high, meaning that the Silver-1 will not demand much current from the amplifier. It should work well with tube…

With the introduction of the 1000 Be series in 2005, Focal slipped its exclusive, high-performance beryllium tweeter out of the stuffy-looking Utopia series and into a sleeker, more stylish, more modern form.
The sound kept pace with the new look: from warmish, comfort-food rich to faster, leaner, low-fat nouvelle. The 1000 Be series brought Focal to the attention of a new segment of the audio enthusiast marketplace and, according to the company, the handsome, floorstanding 1027 Be ($7995/pair), enthusiastically reviewed by Sam Tellig in Stereophile in November 2005, quickly became a…
The moody, Coltrane-esque title track of guitarist Pat Martino's East! (SACD/CD, OJC/Mobile Fidelity UDSACD 2018) sounded every bit like the somewhat flawed but immediate and transparent 1968 recording that it is, and while the piano exhibited the boxy, distorted coloration typical of that era, it didn't get lost in additive lower-midrange slop, while the delicately drawn percussion shimmered cleanly against a black backdrop. Locked into the right channel, the sound of Martino's hollow-body electric guitar believably combined wood, vacuum tubes, strings, and the soul of Wes Montgomery.

The Focal Electra 1037 Be was significantly more sensitive than normal at an estimated 90dB(B)/2.83V/m. However, its plot of impedance magnitude and electrical phase (fig.1) indicates that it is a demanding load for the partnering amplifier in the lower midrange and bass. Not only is there a minimum value of 3 ohms at 33Hz, but there is a combination of 4.25 ohms and –47.5° capacitive phase angle at 27.3Hz. Fortunately, music with significant energy below 40Hz is relatively rare, but an amplifier that has no trouble driving 4 ohm loads at high levels will still be…
Thirty-five years ago this month, the first issue of a new audio magazine—cover price 50 cents—cautiously made its way out of a Philadelphia suburb. Its black'n'white cover featured a chessboard adorned with tubes and XLR plugs. Its 20 advertising-free pages included a feature on how to write an ad for an audio product, which had been penned by one Lucius Wordburger, a footnote helpfully pointing out that this was the nom de plume for one J. Gordon Holt, "who wishes to remain anonymous."
Gordon was a refugee from mainstream audio publishing—he had been technical editor at High Fidelity…
Dear High-End Dealer,
I want to tell you about the one that got away. Diane X is a perky, health-conscious, tennis-playing woman of 52. She lives in a huge house nestled into three acres of wooded hillside. Her home is notable for its architectural excellence and meticulous craftsmanship, for its lovely antiques and rare artworks. A four-year-old but showroom-new luxury sport/utility vehicle sits unused in her garage: she prefers the Lexus. She also loves to sing: Diane is the president of her local Choral Music Society.
Until recently she was the loyal wife of a successful…
Every two or three years my family and I travel to Disney World in Orlando, Florida—one of those places I used to think I'd hate, but which I always enjoy in spite of myself. No such trip would be complete without visiting the Mitsukoshi department store at Epcot Center, which represents the pinnacle of Japanese consumer culture. At the Epcot Mitsukoshi store—the 430-year-old company's only US location—one can buy the finest of everything, including the rarest and most expensive writing papers and inks, the most exquisitely crafted pottery, and the loveliest freshwater pearls on Earth. Young…
Once the Koetsu Black had acclimated to its new surroundings, its sound was lovely: smooth, textured, exceptionally colorful, and just a little rolled off in its treble range. A warning bell may go off in the minds of some readers on seeing a reviewer ascribe a "dark" sound to a product that's been painted black, let alone named Black. Fair enough: Let's just say the Black isn't bright. It may well be timbrally correct in some systems and to certain ears; in mine and to mine, it came off as just a mite huskier than neutral—which I enjoyed. It gave the horns in Tippett's ingenious Sonata for…
