Technics has researched the problem of cartridge/tonearm matching and developed the worlds first variable dynamic damping system, used in its EPA-100.By matching the damping characteristics to the compliance and mass characteristics of the cartridge, Technics has succeeded in greatly lowering the low-frequency resonance peak of the cartridge/tonearm assembly. The EPA-500 has further expanded on this concept so that you will now be able to obtain performance from your cartridge by selecting a tonearm with the most suitable effective mass, arm resonance and damping.The EPA500 tonearm features interchangeable arm units, titanium nitride tapered pipe arm, dynamic damping system, Gimbal suspension arm base for various arm units, helicoid height adjustment ranging up to 20mm and minimum bearing friction of 7mg in all directions.SpecificationsBase: arm base with arm unit interchangeabilityPivot construction: gimbal suspension typeArm height range: 42 to 62mmFriction: 7mg vertical/lateralMounting hole diameter: 62mmArm type: interchangeable arm unit with dynamic damping systemEffective length: 250mmMounting distance: 235mmOverhang: 15mmEffective arm mass: 8g (without cartridge)Applicable cartridge weight: 5 to 7gStylus pressure: 0.75 to 1.75g (2.75g with shell weight)Resonance peak: below 6dB The arm is located in Melbourne, Australia and will be safely packaged for worldwide delivery, local collection is of course welcome.
