I have mine on the bottom shelf of my Arcici suspense rack. then it's sitting on 3 dh cones and footers. Just more...real similar to what cones do for a cd player...tightens up the bass a little, more air.
Mine is on a Nueance shelf with EAR footers. I've tried it with a BDR shelf but was not pleased with the PRAT. I've tried BDR cones along with titanium and brass cones, all are less pleasing that the EAR.
