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.

It seems to me that my review of Monitor Audio's Silver 8 loudspeaker was published only a few months ago. Actually, it's been three years. The Silver 8 so impressed me that I bought three of them, along with two Silver 2 bookshelf speakers, for my multichannel system in Connecticut—and still greet them as the newcomers to my system. So installing and reviewing their successors, the 300, from the sixth generation of Monitor's Silver line, seemed very familiar.
