I have BDR source shelves under all my gear (TT, sacd, pre, power). Without question they greatly improve the overall coherance of the music with also a greater level of detail, depth and dimension. When you use a shelf or source always use cones down under to create an air space. Below the component point your BDR cones facing up with the tip in contact with the component. When doing this everthing has a more relaxed and open sound.
Note the shelf is good for lighter compoents under 40 lbs.
