Alternative to VPI motor for Aries 3?

I have the latest Aries 3 and according to this webpage:
http://www.vpiindustries.com/products_aries3.htm

It has the following description of the motor:

The solid black aluminum motor assembly is almost 10 pounds and contains a low noise 300-RPM synchronous motor with Delrin motor pulley. This is a very low noise system as the fundamental resonance of the motor is at 5 Hertz. Well below the ability of a cartridge to pick it up.

So this is 'supposed' to be a low noise motor, but I can hear the resonance noise within 2 ft, and I believe the cartridge actually pick up the noise which is audible during the quiet passage of a song.

The question is, is there any other motor that's quieter than the VPI??
