1、NAD turntables have everything needed to extract the very best from your LP collection. Each record playing system 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

2、 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 th

3、e 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. The precision AC synchronous motor drives the massive platter via a synthetic rubber bel

4、t to isolate the record surface from even the smallest vestige of motor vibration. This proven design has the dual advantage of low background noise and long term reliability. The platter itself, made of a special non resonant MDF material, is located on a precision machined bearing utilizing a stee

5、l shaft that sits upon a hardened steel ball at the bottom of a brass sleeve. The tone arm offers perfect geometry and excellent control of spurious resonance, and is an ideal match for the supplied cartridge. The statically balanced design also incorporates a linear magnetic anti- skate compensator

6、 for ideal tracking characteristics across the entire playing surface of the record. Every aspect of each turntable design is carefully considered and fine tuned for the best possible performance. These minimalist designs, using ideally chosen materials and precision manufacturing, will astound you
