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.

On Thursday, February 13 from 5 to 9pm, Manhattan retailer Sound By Singer will present a musical evening centered around the Gryphon Audio Designs Ethos CD player/DAC. Alongside host Andrew Singer, Philip O'Hanlon of On A Higher Note—Gryphon's North American distributor—will demonstrate the Ethos with hand-curated selections . . .

In celebration of their first 10 years in business, Volti Audio unveiled a newly redesigned version of their Rival SE (Special Edition) speaker ($19,900/pair), seen here in an eye-catchingly exotic bubinga wood veneer (a rosewood option is also available). Although its side-curved form appears quite substantial, the horn-loaded hybrid floorstander can be sonically suitable for larger or smaller spaces. With its horn drivers and a sensitivity spec of 100dB, the Rival SE also makes for an easy to load-perfect for the 300B-powered BorderPatrol P20 EXD amplifier. The three-way Volti also features matching external crossovers that are user-adjustable, and Triode Wire Labs internal wiring.

Suncoast Audio presented Fyne Audio F702 speakers ($8995/pair) in their US debut. Handmade in Scotland, the two-and-a-half-way floorstander features a concentric point-source tweeter/midrange array with a titanium center that seemed almost hornlike in its appearance and delivery.

When I heard the Stenheim Alumine 3 at AXPONA last year, I frankly wasn't impressed. The tweeter seemed a little hot, the character a little buzzy. I learned just this morning that Jean-Pascal Panchard, Stenheim's CEO and designer, wasn't happy with them, either. He didn't think they were ready, but they had committed to presenting them at AXPONA, so he kept his commitment. They only produced three pair in that configuration. After that show, changes were made.

Wynn Audio of Toronto presented a lovely demo with a couple of new products: the Swiss-made EMT STX 5/10 step-up transformer ($9280), which employs a toroidal transformer with pure silver wiring to provide output options for 14dB or 20dB of gain with a lower noise floor for higher resolution, and the Métronome DSS Streamer (DSS stands for Digital Sharing Streamer), which was released in January but seen for the first time here in the U.S.

Known primarily for its sharp-looking tube amplification ranges, Raven Audio of Texas has been busy cranking out a plethora of new products, including some entirely new categories for the company: the debut of two loudspeakers (with the same high efficiency, spec'd at 94dB) and a line of cables. Raven presented two active demos: a reference system and a more affordable setup featuring the maker's latest offerings.

This was a surprise.

When I walked in to this room and saw these skinny towers, I didn't expect much. When I saw that they were wireless, I expected even less. But the Piega 701s made some very fine sounds, with good bass, tweeters that didn't draw attention to themselves, and a stereo image that didn't collapse when I moved off-center.

It's not every day that you encounter a high-end loudspeaker that the end user actually assembles. Pure Audio Project has taken this unorthodox approach in introducing its brand-new Quintet10 Horn2 speaker at the Florida show . . .
