C 558 Belt-Drive Turntable

Description

NAD C 558 Belt-Drive Turntable

The C 558, uses a sophisticated power supply transforming the AC voltage of your wall socket into a pure DC voltage. This DC voltage is then regenerated into a clean AC voltage that powers a precision clock motor with near perfect speed consistency. This isolates the motor from noise and voltage fluctuations that occur in the unfiltered AC mains that can cause speed instability. A specially developed rubber belt is flat ground for precision and drives a non-resonant sub platter that is precisely machined for smooth rotation. This sits in a brass bearing with a hardened steel shaft. All of these parts are carefully developed to work together to provide a remarkably stable and precise rotation of the disc. The C 558’s tonearm 9” long offers low tracking distortion while maintaining rigidity and low mass required to stabilize the cartridge. By allowing VTF and Azimuth adjustment it gets precise tracking with low distortion and record wear. The glass platter and massive plinth combine to extract all the energy from the disc while isolating unwanted external vibration. The plinth of the C 558 is solid MDF, as opposed to the particle board or plastic that is commonly found at this value, and is CNC machined for precision.
