Sonus-Faber-GUARNERI-MEMENT.jpgIn December 1993, when the original Guarneri appeared, who knew it would turn out to be the milestone model in the Italian speaker company's history? Once could easily postulate, even back then, that designer Franco Serblin was fired up by a need to raise the stakes in the speaker market. After all, every time Sonus faber came up with a new look (even that of the Extrema, which was an isolated model), lesser brands ripped off the form.

By 1993, though, the company was sophisticated enough to indulge in more than cabinetry fillips, and the brand was well into the stage where it was specifying proprietary drivers, or providing input into their suppliers' designs. The gloves - probably kid, made by Forzieri - were off.

What dominated the entire Homage series that it launched was Serblin's drive to emulate the Cremonese violin makers. Thus the Guarneri's cross-section reflected that of a lute, the woods were aged and assemblage using centuries-old techniques. Even the glues and varnishes were made from recipes that harked back centuries. While skeptics initially posited that the Guarneri exuded style over substance, the sound was simply breathtaking, and the speaker was an instant hit. In addition to siring the later Homage models and many dozens of rip-offs, it sold in its original form in serious numbers for 13 years.

Back then, I said it was one of the best small monitors I'd ever heard, and I have owned a pair ever since. It has been - after the Marantz CD12/DA12 CD player - the longest-serving reference component in my review system. My opinion, over the years, has been continually reinforced. You can therefore guess that I approached the Memento the way a devoted Porsche 911 or Leica M-series owner greets the replacement model: eager, nervous, curious, like preparing for a not-so-blind date.

Despite the singular brilliance of the Guarneri, a catalogue mainstay familiar to many of you, the differences are numerous, but obvious only to obsessives. Indeed, only the single terminals (instead of bi-wiring) and the prow on the grille tell non-geeks that they're auditioning the Memento rather than the original. But it is, cabinet shape aside, a virtually new speaker; even the supplied pedestals have been tweaked, the wedge-profiled base producing a six-degree slant. This ensures that the drivers' emissions centers are on the same plane. This allows the speaker to produce more coherent phase alignment and response.

For the active ingredients, the mid/woofer is derived from the Stradivari and Amati midranges. As the company put it, between the original Guarneri's and the Memento's mid-bass drivers are 12 years of technological development. The main difference is the new shaped cone and the use of Kapton instead of aluminum as the coil's support. "As a result, we have a 150mm, ultra-dynamic linearity driver with a CCAW/Kapton eddy current-free voice coil. Its dynamically linear magnetic field motor incorporates Kellogg and Faraday rings, and all moving elements have been optimally ventilated for resonance-free response."

So, too, does a new tweeter replace the Dynaudio Esotar of the original. A 25mm ring radiator tweeter with dual toroidal wave developed directly from that in the Stradivari, it's identical to one in the Amati Anniversario. Sonus faber feels that it is "more linear, more focused and a little more directive." It takes mere seconds to confirm the company's belief that the Memento's sound is "more detailed and refined if compared with the Guarneri Homage."

While the dimensions and shape are more or less the same as those of the Guarneri Homage, at 210 by 340 by 380mm (W/D/H), the wood is now solid maple instead of solid walnut and the small black wood segments have been changed to increase their ability to reduce and control resonances and vibrations. This produced an added benefit during manufacture: "There's no more need to tune the cabinet with some copper/lead devices, as [there] was for the older model."

Naturally, with two new drivers, a new crossover followed. Proudly, the company will tell you that the new one is less complex, though it maintains first-order networks "which link this project to our past tradition. It was designed using the philosophy of the least interference with the musical path. So it is a conceptually minimalist implementation using six-decibel/octave slopes and components of the highest quality and coherence." Its crossover point is 2.5kHz, and the impedance is four ohms. Like its predecessor, the Memento is - simpler network aside - still a hungry bugger of a speaker. Forget the 30-200-watt recommended range. Less than 100 watts is a waste of time.

Another minor change, beyond the aforementioned reversion to single wiring, is that both terminals are nickel rather than one gilded and one nickel. Unsurprisingly, given that Franco and his son-in-law Massimiliano (a metallurgist) are the geniuses behind the sublime Yter cables, the entire matter of wiring and connectors has been addressed with new version. Inside the Memento, replacing the silk-covered Litz of yore, is the uniquely structured silver-palladium alloy conductor found throughout the current Homage range. I will tell you at this point that Yter turned out to be the only wire worth using with the Memento, as its symbiotic nature provided a coherence and seamlessness that no other cable could match.

Aesthetically, the Guarneri is still pretty enough to silence bitchy wives, and it now comes in the red finish that previously existed for only a handful of pairs, but which found favor with the Amati and Stradivari. That wonderful graphite finish is an option, and the leather baffle has been restyled.

Sonically, well, you need to approach this with a caveat, and that caveat is: "Be ready for surprises." My all-time favorite audiophile joke (I only know two, besides certain brands that qualify as farcical) goes like this: How many audiophiles does it take to change a lightbulb? Answer: Three. One to change the bulb and two to argue about how much better the old one was.

I've never been of that school, preferring to give the benefit of the doubt to any manufacturer with the guts to revise a classic. One needn't have worried with the Guarneri Memento. It audibly and clearly advances on the ur Guarneri. Subjectively, there seems to be more weight down below, maybe a shade more extension, certainly a lot more control. Accusations of too much euphony haunted the original; the Memento is indubitably more detailed and transparent.

But the character? Despite sounding bigger - the scale of the stage it creates will baffle those who equate the function with cabinet size - and although it exhibits a far more convincing disappearing act than the original, the Memento (set up with the necessary severe toe-in that crosses the speakers in front of the listener) resembles the original in key ways. With vocals in particular - and I used a spread ranging from the broadband power of Jackie Wilson to the frailty of Sinead O'Connor - there remains a naturalness that places the vocalist texturally and spatially in the room, just in front of the speaker line. Strings still shimmer. Transients remain sharp but non-aggressive. To put it another way, it sounds more real and detailed, without sacrificing any warmth.
