Dragon-CT (Computing Turntable)
Definition of Perfection!
You've watched tonearms weave while tracking a disc; you've heard pitch vary; you've closed your eyes and listened to instruments wander in space.
Perhaps you thought it was your imagination! Some days the problem seems worse than on others.
It's not your imagination. It's groove eccentricity.
Records aren't perfect. Disc center holes may be too large, off center, or both. Unless you mount a disc perfectly, the groove won't be concentric with the axis of rotation, and, if the spindle hole is off center, the groove will be eccentric no matter what you do.
As the stylus tracks an eccentric groove, it weaves back and forth changing relative speed and generating i wow. And, as the stylus deflects from side to side, interchannel phase and separation vary (so does distortion!), and instruments wander about.
Even if the disc and turn, table meet international standards, groove eccentricity can produce peak wow of as much as 1/2% at the inner groove-far more than you'd expect from a turntable!
DRAGON-CT solves these problems. Its Absolute Center Search System measures actual groove eccentricity and relocates the disc so that the groove is concentric within 20 microns! The procedure is automatic and takes only a few seconds. Once DRAGON-CT has relocated the disc, eccentricity wow vanishes, pitch stabilizes, and instruments remain fixed in space.
DRAGON-CT is an integrated disc-playing system designed for today's finest cartridges. It's high rigidity, low-mass, semi-automatic tonearm has extraordinary warp-tracking ability thanks to its precision bearings and viscous damping system. A unique double-cabinet dual-suspension construction isolates the disc from external vibration and acoustic feedback and ensures remarkable sonic clarity.
You'll find DRAGON-CT at select Nakamichi dealers. You owe it to yourself to find out how good your records can sound! For more information, write Nakamichi U.S.A. Corporation, 1101 Colorado Avenue, Santa Monica, CA 90401.
