YG Acoustics' very fine-sounding midrange unit contributed to the lovely sound on YG Acoustics' Ascent loudspeaker ($19,800/pair). Easier to drive than the Colorado company's larger models, it uses the same drivers as in the Carmel and Hailey loudspeakers, but with a new waveguide on the tweeter.

Alon Wolf can be mesmerizing. When the founder of Magico gets going on one of his favorite subjects, loudspeaker design, the strength of his convictions, depth of technical knowledge, and sureness of response are enough to hush many a skeptic into silence.

After hearing the Stello stack, I thought I had heard it all. But in the next room, April Music President Simon K. Lee blew my mind even more with the one-piece Aura note Music Center ($1850). This little baby, available through a dealer network, even includes a USB port on back, a second USB memory stick port on the side, a built-in tuner, and two RCA inputs. Paired with the Aura speaker ($650/pr), the parallel single-ended MOSFET design (thank you, Nelson Pass) sounded a bit more mellow and soulful than the Stello stack. (It would have probably extended as low as that stack if it had been paired with the B&Ws).

Amelia S. Haygood, the sound-conscious founder and president of record company Delos International, died on March 19 at the age of 87 after a 12-year battle with cancer. Survivors include pianist Carol Rosenberger, her closest friend and Delos vice president, artists and repertoire; Robert Haygood, her stepson; several nephews and nieces; and her extended family at the pioneering classical label she founded in 1973.
