No particular thoughts or recommendations, other than most of Herbie's Audio Lab products work superbly on their own. If using a rollerblock, placing a grungebuster Dot as a decoupling interface between roller block and shelf or component is usually beneficial. Grungebuster Dots are also always beneficial between a platform and shelf, without the resonance issues and subsequent effect on linearity that innertubes have.
