We have done extensive research on this exact issue and without hesitation I can recommend isolation and dampening systems. This will make a quantifiable and demonstrative improvement on all PLCs. This should be considered very important for all of the components, but, in regard to a PLC, this is not a subtle improvement, especially when the PLC is directly on carpet.
