The NAD C555i turntable has everything needed to extract the very best from your LP collection. The C555i Turntable includes a perfectly matched tonearm/ cartridge to yield high performance reproduction and comes complete with a highly reviewed moving magnet cartridge pre-mounted and ready to play. A non-resonant Polystyrene dust cover is also included. A “rigid plinth” design concept that keeps all elements of the turntable in perfect alignment, providing the solid foundation required to reproduce even the most subtle of musical nuance. This design releases the maximum amount of energy from the record itself, leading to a dynamic and highly detailed sound without the colourations common to other designs. Specially designed isolation feet filter out parasitic vibrations in the musical frequency range.
