Ever since the appearance of the TD-124, people have been engaged in endeavours to "silence" the motor. The first serious attempt was by Thorens own engineers by means of the double suspensionrubbers. Recently the members of the Audio Team (H.A.T) developed a spring modification for any TD-124, which offers a dramatic improvement over any decoupling solution so far. Apart from taking the motor out of the turntable altogether which, of course, is turning system integrity upside down . Below you see  pictures and measurements of four different versions of motor decoupling.

Metingen MK1Motor vibration 100 Hz at -57 dB

Thorens TD-124 MKII with double suspension rubbers


Metingen MK2

Motor vibration 100Hz at  -63 dB

An improvement of 6 dB over the MKI version
