Stereophile writers have reviewed three versions of Sonus Faber's stand-mounted, two-way loudspeaker, the Guarneri: Martin Colloms on the original Guarneri Homage, in 1994; Michael Fremer on the Memento edition, in 2007; and Art Dudley on the Evolution, in 2012. The Guarneri has always been an expensive speaker—$9400/pair with matching stands in 1995, $15,000 with stands in 2007, $20,000/pair plus $2000 for the stands in 2012—but its prices have been related to its build quality and appearance, both of which have always been superb. Now we have the Guarneri Tradition, for $15,900/pair, including stands.

Merging Technologies' original NADAC Multichannel-8 ($11,500) is an impressive device. (NADAC is an acronym for network-attached digital-to-analog converter.) It has eight channels of high-resolution D/A conversion, and two more for its front-panel headphone jack; a cutting-edge Ravenna Ethernet input (based on the AES67 Audio over Internet Protocol, or AoIP); and, to my delight, a real volume-control knob on the front.

Earlier this week, we posted a video blog with PS Audio's founder and CEO Paul McGowan giving Jana Dagdagan and me a post-CES tour around the Boulder, Colorado company's factory. Following the tour, I sat down with Paul in Music Room One and in a wide-ranging conversation, we talked about amplifiers and loudspeakers, DACs and audio systems, and the state of high-end audio.

Queen of Bebop: The Musical Lives of Sarah Vaughan
By Elaine M. Hayes. 419 pp. Ecco/HarperCollins, 2017. Hardbound: $27.99. Available in eBook and digital audiobook formats.

This is the second biography of Sarah Vaughan (1924–1990), whose towering vocal talents took her to the top rung of the jazz ladder, beside Billie Holiday and Ella Fitzgerald. The author, trained as a classical musician, puts far more emphasis on the singer's recordings than Leslie Gourse did in Sassy, her 1993 Vaughan biography. Hayes's grasp of music, and her definitions of the musical terms she uses, make this the better account.

Thursday March 1, 6pm–8pm, Suncoast Audio (7353 International Place, Unit 309, Sarasota FL, 34240), is hosting an event featuring presentations by Walter Swanbon, the US Harbeth distributor, Vince Galbo from MSB Technologies, Kevin Hayes from VAC, and Jett Logan from AudioQuest. Suncoast will be raffling off a free pair of Harbeth speakers—must be present to win—and products being demmed and discussed will include the MSB Select II DAC and new MSB Reference Transport, the new AudioQuest Storm Series Power Cables, and the 40th Anniversary Edition Harbeth Monitor 40.2 speakers driven by VAC Signature 200iQ monoblock amplifiers.

New, well-recorded albums of Verdi arias from two of the Metropolitan Opera's biggest and most heralded stars - Bulgarian soprano Sonya Yoncheva, 36, and Maltese tenor Joseph Calleja, 40, give as much cause for excitement as they do for pause. As fine as the singing may be on Sonya Yoncheva: The Verdi Album (Sony) and Calleja: Verdi (Decca), the ways in which these artists push their voices to encompass heavier repertoire raises questions as to how long they can sustain such pressure on their instruments without serious sacrifice.

Hi-Rez and Surround-Sound mixes included in Deluxe Edition boxed set.
