Sumiko MDC-800 The Arm


The Sumiko MDC800 'The Arm' is a high end design loosely based on the legendary Breuer tonearm.

The arm features a fixed headshell, large arm tube, gimbal bearings, decoupled counterweight and spring applied VTF and anti-skating force.

Different counterweights can be fitted for cartridge matching.


Effective arm length: 228.6mm

Pivot to rear of arm: 63.5mm

Cartridge overhang: 18.17mm

Offset angle: 24.14 degrees

Mounting distance: 210.43mm

Height adjustment range: 35 to 57mm

Tracking force adjustment: 1.75g max calibrated (more using counterweight)

Bearing type: 4-point gimbal ball race and cone

Bearing friction: less than 10mg

Arm lead capacitance: 100pf

Cartridge weight range: 4 to 18g

Effective mass: 11g (with L weight)


The sound of the MDC-800 was smooth and relaxed. Bass definition, always good, was marginally improved with the production sample, and it demonstrates fine depth, neutrality and tunefulness - £795 HiFi Choice 1983

Sonics, especially ambience

Sonics, especially ambience retrieval can be improved with the removal of the finger-lift which appears to ring along with cartridges. Otherwise a superb design if a headache, like so many others, when it comes to adjusting VTA.
