Hi Paul, your Lightspeed Attenuator chassis is fully shielded alloy, it gets it's RF sink earth via the interconnects. Vibration doesn't come into it as there is nothing to get vibrated as it's passive, even the active led's are immune as they are gas element, no filaments. The feet I attach are soft silicon/sorbethane compound anyway just in case. Glad to see you love as much as others do. It would also be unsuccessful to be transplanted within pre's or poweramp environments as the temperature is too erratic within these chassis for the Lightspeed components to behave stably, I even physically couple all the ldr's together after precise matching and then pot them in hard wax to keep everything stable in the your production one.
Cheers George
