Dynavector DV507 MKII Tonearm
The new MKII version of the Dynavector DV 507 tonearm builds on the strengths of the original DV 507 which has enjoyed the highest reputation among audiophiles world-wide. The use of precision stainless steel bearings give superb dynamic sensitivity and a stabilized tracking performance without any deterioration through ageing. A larger arm lift gives a stable lift action which maintains its performance over long periods enabling cartridges to be raised and lowered without stress.
As it is a bi-axis inertia controlled tonearm the DV 507, no matter the type of cartridge can trace the music signal grooves cut in the recording with extreme accuracy. The DV 507 also provides superb trackability on warped recordings. Resolution and musical detailing are quite remarkable.
The new style headshell is suitable for use with a wide variety of cartridges. It is machined from aluminium alloy and has an EIA standard connector. This allows the cartridge to be rigidly mounted and the azimuth adjustment. pure 6N wire is used in lead wires for the headshell and internal wires of the arm. The new type damper with a powerful Neodymium magnet gives better damping and ensures any adverse effects on tracking performance are minimized. The new plug-in connector ensures good contact is maintained with the Rhodium coated headshell contact pin during long-term use. A machined aluminium connector is used. The 5 PIN connector conforms to the DIN standard. Double balanced type shield wire and 4NOFC/6N hybrid construction arm cable.
A cartridge generates an audio signal by the differential motion between the cantilever and the cartridge body. A non-contact, electro-magnetic damping mechanism has been been designed to prevent sound distortion and poor tracking performance arising from arm resonances induced by low frequencies. In this system, a curved rod attached to the rear of the arm is mounted in a magnetic field supplied by two powerful neodymium magnets. Any minute movement of the rod, due to an undamped arm resonance, causes an eddy current to be induced in the rod, which in turn interacts with the magnetic field to return the system to its rest state.
Most tonearms have some frequency response irregularity in the mid-low range at about 100-150Hz. This is called multi-resonance or anti-resonance. To eliminate such unwanted resonances, a dynamic damper has been installed in the bottom of the sub arm. This solution was developed after much theoretical consideration and experimentation.
