Major Changes for YG Acoustics
Called "BilletCore" by the Colorado company, the aluminum cone for the midrange and low-frequency drive-units used in the top-of-the-line Anat III Reference ($111,000/system) and the smaller three-way Kipod is milled from a solid block of aluminum. In the case of the Anat subwoofer, the starting point is a billet of aluminum 2.5" thick weighing 16 lbs, compared with the finished cone after a day of work, which is 0.008" thick and weighs less than 1 ounce. Stiffening ribs are left on the rear of the cone and the final step is to black-anodize the aluminum. The benefit of machining the cone is said to be improved unit-unit consistency and rigidity compared with a conventional spun, cast, or pressed metal diaphragm, which pushes break-up modes even farther out-of-band.
Though YG was in the same room as in previous CESes, they had taken heroic measures this year to tame its acoustics, as can be seen from the photo. The result was worth the effort. In a system that included dCS Scarlatti digital front-end, a Veloce battery-powered preamp, Tenor 350M monoblocks, and Kubala-Sosna Master Reference cables, the Anat II Reference produced a warm, detailed, full-range sound. Particularly impressive was a version of Sting's "Roxanne" from Italian singer Petra Magoni of Musica Nuda. Both the voice and the solo double bass accompaniment had a palpable presence but without sounding forced or exaggerated.
