Building Amp Stands

I was fortunate to find a plank of 2 inch thick purple heartwood, which I then had cut into two pieces to be used for amp stands for a pair of Atma-sphere M-60 mk2.2 monoblocks. Currently, each amp is sitting atop of a set of Aurios 1.0's, which, in turn, sit atop of a Syposium shelf which rests on a carpeted floor.

I want to put a set of 3 spiked brass feet on the bottom of each piece of heartwood, placing the Symposium shelf/Aurios atop of the spiked heartwood stand.

I've seen large brass spikes which attach to the bottom of the amp stands via adhesive pads (Focal Points, Revelation Audio Points). How would this method of attachment compare with drilling and tapping a threaded sleeve to secure the feet? Even though a professional woodworking shop would do the drilling and tapping, purple heartwood is a BEAR to work with, with the remote chance of cracking the wood, and the increased cost for the shop's services.

Thanks to all for your valuable help! I've actually decided to use a set of speaker cones (brass) that I'm not currently using. My speakers are sitting on top of Aurios, placed on top of a carbon fiber board. I am also waiting to perhaps purchase the new State Technologies amp stands, which are supposed to cancel out stray magnetic fields and eddy currents which are produced by all amps. Preliminary indications are that these stands, which are the first attempt to solve a previously ignored fidelity problem, are spectacular!

Slappy, why do you hate working with purple heartwood? What type of sandpaper do you recommend?
