What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Nakamichi Dragon-CT


The Absolute Center Search System is refined and simplified, yet the same high performance is achieved. A brilliant design achievement is now available in all new format.

The DRAGON-CT is Nakamichi's second analog disc player. As its name suggests, this remarkable turntable features revolutionary technology and peformance that sets a new standard of performance in its field, just like the "Dragon" Auto-reverse Cassette Deck. Like the original TX-1000 Computing Turntable, the most unique feature of the DRAGON-CT is the Absolute Center Search System. The principle behind is the same as that of the original system. A special sensor arm is employed to precisely detect record concentricity error, shift the record's axis of rotation, and completely cancel record concentricity error and tonearm wavering for vastly improved reproduction accuracy, musical transparency and stereo imaging. 

The DRAGON-CT Absolute Center Search System has been newly designed, however for exceptional precision with greater simplicity. Musically, the benefits of this unique system are simply breathtaking. Clarity, detail and nuance that was never before heard with conventional turntable systems is brought out of the record's grooves as if by magic. The apparent location of instruments and vocalists in the stereo sound field is made clear and distinct, eliminating the "muddied" sound that results from inadequate separation and stereo imaging.

The DRAGON-CT also boasts superior wow and flutter characteristics thanks to the use of the Nakamichi Super Linear Torque motor. The cogging-free performance it offers drastically reduces flutter, for greatly improved musical transparency. Vibration and acoustic feedback are thoroughly avoided with a dual suspension system which effectively stops surface vibration transmission, and special double cabinet construction that suppresses airborne sound transmission. Designed to maximize the performance advantages of high-grade audiophile cartridges, the DRAGON-CT includes a high-rigidity, oil-damped straight tonearm that maintains the ideal relationship between stylus and record groove, for optimum tracking performance with a wide variety of cartridges.

Semi-automatic operation
Tonearm pipe is interchangeable
