Based on the award winning AMG 12J2 12” tonearm, the new 9” tonearm use a scaled version of the AMG Patented Dual-pivot bearing. The vertical bearing, similar to a technique used in helicopter rotors, utilises 2 steel wires that allow fine azimuth adjustment while eliminating bearing play. The horizontal axle is hardened tool steel needle roller bearing. The aircraft grade aluminum armwand is anodized for resonance control. Identical to the 12J2, the new 9” tonearm’s internal wiring is multiple stranded high-purity copper, and features magnetic anti-skate and precision locking VTA adjustment. The 9W2, with a pivot to spindle distance of 211mm, is designed for the Linn LP-12, as the second arm on an AMG Viella 12 using the TWIN armboard with OVAL SME mount adapter, or other turntables that accommodate this length.
" STEREOPHILE " 2015 Class A Recommended Component: The German-made 9W2 tonearm from turntable specialists AMG combines a traditional horizontal bearing with a vertical bearing that is unique in its field: "an upright pair of 0.4mm spring-steel wires that are perfectly straight when the tonearm tube is balanced, yet flex in tandem and yield to the armtube's mass when the counterweight is moved closer to the twin fulcrums." The result, he reports, is a near-ideal combination of zero play and absence of friction. VTA and azimuth are easily adjusted, and a magnetic antiskating mechanism is included. Used on his Linn LP12—for which the 9W2 was apparently designed—the 9W2 was, said AD, "the first Linn-friendly arm I've heard that has made me stop sobbing about the demise of the Naim Aro: a considerable feat." Also with reference to his past favorite tonearms, AD added: "None surpasses the 9W2 in sheer build quality." (Vol.37 No.10 WWW)
