Hi Dbld,
Thank you for your question.
Rigidly affixing the component to the rack will allow any vibration within the rack (sourced from the floor or from the rack's structure vibrating in sympathy with air-borne vibration) to have a more efficient path INTO the component. That would increase the amount of vibration that is contaminating the signal flowing through the component.
A properly designed vibration control set up would also address internally-generated vibration (from spinning motors, humming transformers and cooling fans) besides just addressing floor-borne and air-borne vibration.
Best,
Barry
