If an analog manufacturer in addition to the drive builds on top of that, motor and tonearm itself, this is a small sensation. If the AMG Viella 12 also sensational sounds? The test gives it away.
In the analog market is more leisurely. New turntables often only differ in weight and shape. The construction is not often rigidly designed and purchased engines power the plate, while SME and Rega Jelco supply to the arms. To bring even a typical turntable thing was not Walter Radav. Therefore, developed the AMG head an own arm and builds for the Viella 12, which costs 12 800 euros, even the motor itself. Not only the design will impress at AMG (analog factory Germany). The Viella 12 at the highest level – what not surprising with perfectionists such as just Walter about and his son Julian Lorenzi is also processed.
The two have armed themselves with several CNC machines to be able to manufacture almost everything themselves. Because of vertical integration is very important in Kehl, Germany. We could take what that means local scrutiny: alone the handle of the tone arm devours about ten minutes of production time.
AMG Viella 12 – precision engineering pur
But back to the construction. The Viella is designed as a rigid concept and has therefore no resilient elements, but stands on three top-adjustable spikes. The base consists of a particularly hard aluminium alloy (ALZNMGCU), which is not cast, but rolled and then finely milled at AMG. The subsequent anodizing is one of the few processes, the Rada of the hand is. This brought him but sleepless nights, because the so-called aluminium alloy, which he uses for sound reasons, particularly difficult even to anodize. However, it retains the full control in the manufacture of the plate bearing – here all parts in the home are made. This camp is a Beaut, turns a hard steel axis on a plastic mirror and that is evenly bathed in the operating of oil.
The camp is linked to the sub base. Both wear the eleven-kilogram and be glued with a vinyl edition turntable the motor via internal belts placed in rotation. To put on the belt is somewhat tricky in practice, because the plate covering the engine. But with a supplied wood-working tools, the task can be solved relatively relaxed.
Quiet engine in Viella 12
A piece of jewelry is the engine made by AMG. Copies of the rod Rada were just not good enough. So he was inspired by a tape recorder motor from the House of Pope. The result: a Brushless DC motor with three coils, which has a similar camp as the Viella. The balance mass of this disc armature of just under 400 grams is impressive. A special feature is also that his internal switching currents sinusoidal change and not abruptly, rectangle-shaped like in usual DC motors. Dieser leads artifice to a much quieter running. Unregulated wanted Rada does not run the motor but. A microprocessor checks the speed during operation and regulates the voltage for the motor if required to. This circuit allows a fine and comfortable adjustment of speed in increments of 0.05 per cent using the controls on the base plate.
The own arm, the Rada has developed and builds, towers over the base on a solid cold, which itself but can be adjusted, if King wants yet another poor model customer. The name J 12/2 after he has the length of twelve inches, which reduces the tangent track wrong angle when compared to shorter Nine-ninths. Thus, even distortions that arise outside the zero crossings, are low. Contrary to similar long arms, the AMG J 12/2 with its effective mass of 12.5 grams among the moderate copies. It fits very well to current pickups. Noch more desirable makes this tonearm, that he has even a patented horizontal bearing with spring bars. This solution looked off ex-pilot Rada of helicopter rotors, as he candidly admits. The design allows for an azimuth correction, with which you can make sure that the needle just scans both sides of grooves.
Immersion in music
Measurements in the TEST factory by stereoplay proved to be less criticism just a bit too high speed, what the testers before the hearing test but balanced. The settings that Lyra Atlas concerned the reference height sensor, because the J 12/2 tracking force and anti-skate has no scales but needed exercise and good tool. When the anti-skating should trust not only a test plate, but merely use the coarse adjustment and finely adjust in connection with popular records by ear. It’s worth, because the AMG Viella could show clear even the smallest changes. After this tuning and on a good and stable table as the Naim Fraim or the TimeTable the AMG offered an extremely fascinating sound panorama – one that the tester in this form had never heard. It joined a sinewy, nevertheless, deep bass. So, only the reference of Linn, the LP could be radical with the tonearm EKOS SE, the benchmark 12 SE. Compared to these top players you could now not simply speak better or worse. No, different characters on the same high Niveau. Dem acted bass the Viella gave a touch more contour, while something full pressure played the LP 12. Here come the music about him, while the Viella still locate sharper put individual instruments in slightly larger recording rooms something direct and accented. Appeared at the Linn the companion in the classic “Cheek To Cheek” with Louis Armstrong and Ella Fitzgerald (“Ella And Louis” / EMI) motivierter and played energetic, the AMG even more left out the piano in the background the sound events are emerging. Conclusion: Also the AMG Viella 12 may call itself now stereoplay reference.
