AMG 12J2 TONEARM
"But that arm! It’s a world-class product, in a field where there are, if we are being truly honest, very few world-class products". - Alan Sircom, HiFi+ UK
“Not only is Roeschlau’s ’arm a veritable sonic vacuum cleaner when it comes to the recovery of low-level detail, it is also highly and easily adjustable.” - Jonathan Valin, The Absolute Sound USA
The AMG 12J2, introduced on the Viella in 2012, contributed to the critical and commercial success of the brand. It’s elegant appearance and precise engineering allowed for the superior tracing of the record groove without increasing mass or moment of inertia found in other 12” tonearms.
The 12J2 was our first tonearm using Werner Roeschlau’s unique bearing design, based on his background in aeronautics. The AMG Patented Dual-pivot bearing Vertical bearing mimics the technique used in the rotor heads of helicopters. It uses two .5mm thick “spring steel wires,” allowing fine azimuth adjustment while eliminating any bearing play or wear. The horizontal axle is a hardened tool steel shaft, precision ground to a backlash-free fit with both a lower needle roller bearing and upper multi-ball bearing assembly. It is extremely precise and maintenance free. The 12J2 uses magnetic anti-skate, multi-stranded internal copper wire, and adjustable VTA.
