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.

I don't believe securing the cones to the hardwood shelf would produce any sonic benefit. If you can find 4 pieces of the wood consider configuring them like a Machina Dynamica Promethean Base. I use these under my M-60's, the resolution increase is immediately apparent. I highly recommend them as amp stands for the M-60.

BTW, the Promethean's use DH Cones, all of which are unthreaded.

I'd go with threaded spikes if for no other reason than the ability to level your stand. Being concerned about splitting, I would think you would want a small diameter tap, like 1/4".

Use the threaded inserts. They are usually made of brass. I'd use 1/4-20, it's a common size, many spikes are threaded to that size.

I presume you are talking about Purpleheart here? (never heard it referred to as purple heartwood but I guess that is what it is being discussed.)

I hate working with purpleheart.

It is a stunning stock when done correctly though

With equipment like yours, you should audition the Sistrum stands with your amps. When you hear how they will open the soundstage you will be blown away. They have a 100% money back guarantee and it is worth a listen. Talk to Robert at Sistrum and he will explain the technology behind them.
