Beskrivelse

En tantastisk arm, sammenlign med hva som helst - jeg har det.

 

The award winning AMG 12J2 12” tonearm features our patented dual-pivot bearing: The vertical bearing, similar to a technique used in helicopter rotors, utilizes 2 steel wires that allow fine azimuth adjustment while eliminating bearing play. The horizontal axle consists of a hardened tool steel needle roller bearing. The aircraft grade aluminum armwand is anodized for resonance control. The 12J2’s internal wiring is multiple stranded high-purity copper, and features magnetic anti-skate and precision locking VTA adjustment.

 

I’ve been using the AMG Viela turntable and 12J2 tonearm as my personal reference for better than four years. AMG recently announced a new version of 12J2, called the 12JT (for Turbo). As a standalone arm, the 12J2 sells for $4,500 whereas the new arm comes in at $8,500. I was excited to see and hear what AMG had achieved with the new arm

I have reviewed or personally used some pretty impressive tonearms, including the Clearaudio Universal Radial Tonearm, DaVinciAudio Grand Reference Grandezza, Graham Phantom, Ikeda Sound Labs IT-407CR12, RS Labs RS-A1, Thales Easy, TriangleArt Oris, Tri-Planar, and the VPI JMW 12.7 Tapered Twelve-Inch Tonearm. All of these are wonderful arms. But for me, the best tonearm I have used in my system up to now was the AMG 12J2. So, what I was expecting from the Turbo was a more impressive looking and easier to set up tonearm with sound that would match my 12J2.
