Just be careful when/if you take off the bottom cover. Make sure that you've unplugged the unit and given time for all the high voltage caps to discharge. It only takes a minute or two for the caps to discharge.
The other thing you can try is putting something that is soft/compliant between the Aurieges and the cabinet. Some soft feet might be the ticket to stop your preamp from shaking the cabinet. I've used sorbothane feet with a noisy turntable motor and Vibrapod feet on equipment in the past with good results.

I think the transformer is tightened down pretty well. The Aurieges has very low hum (almost none) when sitting on a carpet or bare marble floor. It's my cabinet. Like Matt said, the cabinet acts like a speaker amplifying the hum.
Having said that, I may try your solution one day.
