Whatever you make your stands from, put your components on Symposium Ultra platforms. The disc couplers transmit any vibration from your equipment or the room and converts it to a tiny amount of heat. I have these things under my components and the difference was remarkable - especially with my tube amp and preamp. Cleaned everything up.
If cost isn't an issue, get the Symposium Osirus rack.
