I consider the assertion that "because 3 points define a plane, a 3 point distribution system distributes weight better than a 4 point system" to be a fallacy. The actual distribution of the force is determined by the distribution of the masses within the confines of the chassis rectangle that encloses it. I assert that when such a rectangle is supported at only 3 points, a disproportional amount of the force is placed one of the points, and the two unsupported triangular sections of the chassis are now not mechanically damped, so they are free to pick up vibrations coupled from the room.

That simply never happens with a three point system.
My speakers are too large to place on points. The difficulty you refer to is caused by misalignment of the floor, and a 3 point support better tolerates the misalignment, but it's not really distributing the weight any better.

These are very cool looking racks, and as a cyclist I LOVE carbon fiber!!!
Perhaps there are also means to accomplish appropriate conductor routing with constraining devices that attach to the rack or to the shelves. I have not looked into this.
