the Forte shares the V12's mass-loaded, belt-driven, non-decoupled design and makes use of the same platter-bearing design, decoupled spindle, hand-built, brushless DC motor, and platter-dominated form factor. In most ways, it looks like a larger Viella 12, but—again—important engineering and design differences are hidden within.
One of the biggest differences between the standard Viella and the Forte is the plinth height and mass; the older table's plinth was about an inch thick and weighed 17.6lb; the Forte's is 2¾" and 50.7lb. Another key difference, which is hidden from view, is the way the plinth and motor housings are joined: While the V12's bearing and motor housings are bolted onto the plinth bottom (right, below), the Forte's are directly machined into the thick aluminum plinth, greatly improving structural rigidity and mechanical integrity. Also, the Forte's CNC-machined aluminum armbase is 35mm larger in diameter and 15mm taller than the Viella's.
The lastest 12J2 Turbo tonearm featured a unique, dual-pivot horizontal bearing system (for vertical movement) using 0.5mm-thick spring-steel wires (as used in helicopter rotor heads, AMG says) instead of the usual gimbaled variety that can produce "chatter." The bearing arrangement also provides direct acoustic coupling, which AMG says "exactly draws from your record what is truly on it." |
