The Rosso Fiorentino Volterra, represented in the US by <a href="http://blog.stereophile.com/rmaf2010/avatar_acoustics/">Avatar Acoustics</a>, uses a crossover circuit placed in an isolated and damped box within the center of the speaker's cabinet. Here's a look inside.

Sjofn HiFi made a big splash at our <a href="http://blog.stereophile.com/he2007/051307Sjfon/">Home Entertainment 2007</a> show with the Guru loudspeaker, and the company hopes to attract greater attention with their new monitor, “the clue.” I walked into the room just as a thunderous bass note was struck. “Whoa,” I thought to myself as I took the last remaining seat in the packed demo. The little Sjofn speakers ($999/pair) were partnered with electronics from Norway’s impressive Hegel: CDP4A CD player ($4500) and the 200Wpc H200 integrated amplifier ($5000). The system was small, but it produced nothing but big, room-filling sound. There was that well-controlled, thunderous bass and startlingly quick transients.

Jason Victor Serinus got the scoop on Mistral, represented in the US by California’s Napa Acoustic, <a href="http://blog.stereophile.com/axpona2010/mistralnapa_acoustic_debut/">at the AXPONA show</a> earlier this year. I was just as impressed by the looks of the little 40Wpc Mistral MM-4 SE integrated amplifier ($699). It reminded me a lot of the <a href="http://www.stereophile.com/budgetcomponents/308shan/index.html">Shanling MC-30 Music Center</a>.

Here we see the Vitus Audio SIA-025 integrated amplifier ($20,000; 100Wpc running class-A/B) and SCD-010 CD player ($20,000) and Amphion’s Krypton 3 loudspeakers ($20,900/pair). Amphion is now distributed in North America by VMAX Services. This system was very easy to listen to. Even at low volumes, there was no lack of drama, scale, or drive. It was a pleasure catching up with VMAX’s Richard Kohlruss and meeting Vitus’ Hans-Ole Vitus, who tells me he’s got a new phono preamp that Michael Fremer will love.

DSPeakers are active designs with built-in Anti-Mode room correction. We listened to the smaller Servo 300 speaker ($3500) with a Resolution Audio CD player, and, <a href="http://blog.stereophile.com/ssi2010/dspeaker_servo/">just as in Montreal</a>, I was surprised by the small system’s big sound and bold bass. Also on display were DSPeaker’s standalone Anti-Mode correction units, the 8033 C ($350) optimized for home theater applications and the two-input 8033 S ($450) for stereo systems.

Zu did an outstanding job of transforming their drab hotel room into a comfortable, swanky listening environment, utilizing Flor modular carpeting tiles, a nice lounge seat, and some sweet-looking gear: Zu’s Soul Superfly ($2600/pair), a 16 ohm loudspeaker with a claimed efficiency of 101dB, in dazzling green finish, looks right at home with Luxman’s SQ-38u integrated amplifier ($6000) and D-38u CD player ($4000) and a Peachtree Nova D/A integrated amplifier ($1199). At the time I listened, Zu was using Channel D’s Pure Music front-end software ($129) for iTunes as a source, and there was an easy, laidback feel to the music.

The newest Zu loudspeaker is the Omen. I don’t know much about it. The product literature says: “Omen is the right loudspeaker for every concert fanatic, music junky, skater fool, and snowboarding dirtbag; splitting your cash between your lifestyle outside and your lifestyle inside just got a whole lot louder!” So, Zu has a specific audience in mind. At just $999/pair it is also Zu’s most affordable speaker.

The sound was so full, so all encompassing, and so natural in the small Magico room (Tower 9022) that I doubt I'll encounter another display at RMAF that will top it. Certainly on the first day of the show, the sound achieved by (pictured, left to right) Tim Marutani of Marutani Consulting (Emeryville, CA), Alon Wolf of Magico, and Maier Shadi of The Audio Salon (Los Angeles) was so satisfying that it topped anything else I heard on Day One by a long shot. A very long shot.
