Dynavector DV XX2 MKII Moving Coil Cartridge
Dynavector’s Cartridge Tradition
Since its founding in 1978,Dynavector has been a high-end audio manufacturer that has released numerous high-performance cartridges to the world. During development, we take an approach based on academic engineering theory, a tradition that has been passed on by our founder (1). Starting with the unique development of our high-performance vibration systems such as ultra-fine wire high-output coils and gemstone cantilevers, we have focused on the importance of magnetic circuits since the 1990’s. As a result, Flux Damper (2) to stabilize magnetic flux and Softened Magnetism (3) to reduce magnetic flux fluctuations were developed and installed into our cartridges. In 2024,we have succeeded in dramatically improving sound quality by refining the magnetic circuits physical properties to give the best possible performance
Newly Developed Special Annealing Magnetic Circuit
An excellent vibration system is inevitable for a high-performance MC cartridge. The cantilever, coil, damper and rigid body are all important elements to ensure outstanding performance. But we strongly believe that the magnetic circuit in the cartridge is also a crucial element that should not be overlooked. A cartridge’s output signal is generated by the movement of the vibration system within the magnetic circuit. Electricity is generated when the coil vibrates within the magnetic flux produced by the magnet.
A good output can’t be obtained unless the magnetic flux has high density and stability. For our magnetic circuit we use pure iron which has high magnetic permeability and maintains high density in the magnetic flux. Its stability is particularly excellent, making it the optimal material to obtain a distortion-free output. However, when processed to make parts, at the atomic level the metal crystal structure is distorted due to plastic deformation, resulting in a significant loss of magnetic permeability.
To regenerate a distorted metal crystal structure annealing is necessary. The process of restoring magnetic permeability is called magnetic annealing, a process done by heating and cooling processed parts. But a generic magnetic annealing cannot completely restore distortions in the crystal structure thus the magnetic permeability also cannot be completely restored. Also, magnetic annealing conditions vary depending on the material, size, shape, etc. of the part. Therefore, for our new development we focused on finding the best magnetic annealing process by optimizing the annealing temperature, annealing environment, heating duration, heating and cooling rate. As a result,we now can successfully exhibit the full potential of the unique magnetic performance of pure iron.
The new ideal magnetic circuit has drastically improved sound quality with top-notch resolution without distortion, smooth wide-range expression and great spaciousness in the sound field. Enjoy the more natural and dynamic sound of the Dynavector XX-2A cartridge with true harmony created by an excellent vibration system and an optimum magnetic circuit.
