AMT drivers manifest both horizontal and vertical dispersion similar to that of a small dome tweeter, but without the vertical dispersion issues of a ribbon, which requires a listener to be seated at precisely the same height as the transducer to get the superior detail that technology promises. Audiovector further improves its AMT driver by implementing the “Soundstage Enhancement Concept,” sending 30% of the tweeter’s energy backwards—through a long tube so there won’t be any negative interaction with the radiation to the front. There’s less compression and distortion. Klifoth declared proudly: “The technology creates openness, better harmonics, and a generally more lifelike presentation.” Well, of course, he’d say that: They’re his speakers. Time to report on my own experience with the R1 Arretés—and the experience of three other listeners especially qualified to have informed opinions about the Audiovector’s high-frequency reproduction.

Fed with the familiar symphonic work-out that is Britten’s ‘Young Person’s Guide To The Orchestra’, here played by the Kansas City Symphony Orchestra under conductor Michael Stern [from Britten’s Orchestra, Reference Recordings RR-120SACD], the strength of these Scansonic speakers is in the detail they bring out in the various instrumental groups, and their speed and lightness of touch. But as the great final fugue builds to its climax, one can’t help but want for a bit more grunt and scale.

That said, these speakers don’t need massive amplifier power to do their stuff. With a Supernait 3 integrated from Naim, which admittedly falls below the lower limit of Scansonic’s suggestion, they were easily capable of going more than loud enough with no signs of stress, while still sounding both open and dynamic.

When reviewing audio equipment, I always attempt to elucidate what the reviewed component does different than, or better than, or worse than similar components in its price-performance category. This can be difficult if I’m not in-home familiar with the review component’s competition. But it was easy with the Stenheim Alumine Threes.

What separates the Threes from most other top-tier luxury-class speakers is twofold: First, the Stenheims’ look is living-room, partner, and family-friendly, not audiophile weird. Second, and more importantly, the Alumine Threes are not dreadful-to-drive, low-EPDR speakers that will only work with massive crazy-money monoliths that are capable of driving 2 ohms. While the Stenheims responded extremely well to large amounts of high-quality amplifier power, they were equally exciting when powered by a 25W class-A solid state amp and a 22W single-ended triode. I regard this as proof that a well-engineered speaker need not be difficult to drive.
