Have you ever suspected that the component you bought after diligent research is somehow not "typical"? That its sound seems to bear little resemblance to the descriptions in the reviews you read? Sure, you listened to the unit before purchase, but the one you took out of the box at home—was that the same unit? And if you suspect your new unit's sonic quality is below par, just how do you or your dealer go about proving it?

Zesto Audio presented the third generation of its Leto preamplifier: an Ultra version that offers a slew of new features, from upgraded all-analog circuit topology and a new 12DW7 tube configuration to the addition of three gain options (3dB, 6dB, 9dB) that can be saved for different input sources. Full remote control capabilities have also been added for on-the-fly adjustments of input, volume, gain, mono, and muting.

A sub-brand under the Jolida marque, Black Ice Audio used the Florida Audio Expo to introduce the final production models for some new amplification components. (Prior versions seen and heard at previous shows were late-stage prototypes, I was told.) The Black Ice Fusion F11 and F22 integrated amplifiers were shown in striking glass and carbon-fiber chassis with relatively small footprints, which is particularly desirable for the European and Asian markets.

Author's Note: Although I started accompanying Stereophile's loudspeaker reviews with measurements soon after I joined the magazine in 1986, it wasn't until 1989, when we acquired an Audio Precision System One electronics analyzer and the then-new MLSSA speaker measurement system from DRA Labs, that I developed the standardized data presentation that is still featured in our reviews more than three decades later. In this article from October 1991, I summarize the results from the first two years of using MLSSA to test 69 loudspeakers.—John Atkinson

The two A La Carte Productions rooms at the Florida Audio Expo both featured speakers from Austria's Vienna Acoustics, including the North American debut of the Beethoven Baby Grand Reference ($9498/pair). Said to have been three years in the making, the new model is the younger sibling to the larger and aptly named Beethoven Concert Grand Reference tower; the two models share similar drivers and technologies.
