Either take out the spike, or use one of those cones. It's the same thing, in my opinion. You end up with the same surface area contact with the floor. Spikes don't isolate the speaker stand, they couple it to the floor, so that speaker vibrations run out into the room, or let room vibrations go up into the speaker stands, technically. I don't know if that makes it sound better or worse!
There's no such thing as a one-way out for vibrations, because if you remember, for every action, there's a reaction.
I like Stanwal's carpet suggestion
