Luxman PD 441


The Luxman PD441 is a direct drive quartz-locked turntable, but its most salient feature is its ability to remove all kinds of external load vibration thanks to our exclusive load free spindle system.

Actually, the quartz-lock system is effectively only in the suppression of external disturbing load variations ranging from DC to 1Hz, but cannot control those of relatively high frequencies (5-10Hz).

To reduce them, the flywheel effect of the platter must be utilized. The heavier the platter, the better.

But here arises a problem with respect to the life of the bearing.

With the new load free spindle system, the motor itself has the repelling power to float the turntable platter, which makes it possible to reduce the platters weight on the bearing to about 1/5 of its actual value.
