Spikes between speakers & stands, up or down?

Okay so I am curious, I might try a set of spikes between a speaker and stand for a friend of mine. We are looking to replace the rubber stopper type pads to see how it sounds.

Coupling - Decoupling?

So I have seen both orientations of spikes, with them sticking "POINT UP" into the bottom of the speaker, which means installing the spike into the stand top plate, yes easier and less modification to messing with the speaker bottom.

Or "Point Down" which I assume is to drain the energy from the speaker down into the stand…

The bottom of the stands also already have nice solid brass spikes pointing into the floor of course, but I have just seen them again done both ways for the Stand to speaker but never reversed to the floor.

Another option which honestly might be the best is to try something that is NOT a spike device but rather a hard material of a metal flat foot or like Brass puck between the stand and speaker to transfer the energy vs. damping it and maybe loosing some resolution with the current Rubber pads?

Just looking for experience and what is suggested.. I think we rather stay away from spikes just due to the damage to the "spiked surface" and also due to drilling one or the other out to install them..

Also I have some Myrtle wood blocks which might even be a better Idea to give a shot? Keep it in the wood family and maybe get a solid energy transfer to the floor thru the stand that way?

Or maybe taking away the rubber will cause worse results who knows without experimentation right? I would assume the rubber is acting as a De coupler and any other hard material would work more as a Coupler.. So which would be better I guess?

Just don't want to buy anything till' there is a clear concensus on which is the correct direction to go with this.

Thanks
