The TN-550 is an upper-class turntable designed with the concept of combining high style with excellent performance as an analog turntable. The TN-550 provides virtue of analog sound in the highest standard for audiophile who have loved it for decades.
The cabinet combines artificial marble with high-density MDF in a two-layer sandwich structure (Dual-material Chassis). In addition to assuring a high feedback margin, this design realizes clear sound by abating the inherent resonant frequencies of different materials by combining them. The power train employs a belt drive with an automatic rotation adjustment mechanism (Platter Rotation Speed Servo System, or "PRS3") designed by TEAC. Changes in the platter rotation speed are immediately detected by an optical sensor and used as feedback for the motor speed. This allows high-precision rotation speed that can compete with heavyweight-class belt drive and direct drive systems, while allowing a sleek and stylish cabinet design.
