Replacing Audible Illusion Preamp Feet


Own an Audible Illusions Preamp that will soon be going onto a maple-shelved rack and want to replace the stock feet with brass audio points that I have laying around in my accessory box. Can I unscrew the stock feet without loosening and releasing something internal to the unit such as a lock nut that can't be retrieved and will forever roll around inside and bug the heck out me?

Related question - is it better to replace each foot with a threaded footer or can I simply rest the components on unthreaded audio points or black diamond racing cones? If using threaded cones, I'll have to buy a fourth since I only have sets of 3.
I removed the feet on my preamp and replaced them with gold cones held in place with 3m double sided tape. Works like a charm
Leave the stock feet on. Forget the brass spike idea. The maple shelf will provide a balanced sound. The spiked feet on the maple shelf are akin to a video monitor with the contrast and brightness controls cranked up. It didn't do it for me.
BTW I prefered some form of spikes and Stillpoints with my previous MDF and Polycrystal shelfs.
