Audio Points.
What you should hear is potentially little or no difference for the first 8 days or so.
But what you will hear after this settling in period is extended highs with a more natural extended decay and increased speed and dynamics. You should also hear a deeper more defined and controlled bass. Moreover, you should hear a deeper and wider soundstage with better imaging and transparency.
Newbee has a point about the 4 points for safety, but 4 points are also a great potential for compromising sonic improvements of using products like Audio Points.
3 points make a plane and provide the best method for coupling the speaking to the subflooring system.
4 points create uneven rocking scenario and greater difficulty for properly coupling to the floor.
