Redkiwi: Any updates on your findings? I had a computer breakdown and lost this thread. Guys EXCELLENT information and posting!!!!! Has triggered new areas to explore. I did some attempts to hanging equipment but wasn't as committed to audio at that time compared to now. I have now my amp on an airbladder sandwiched between two MDF pieces and noticed bass gain and definition. After reading this definitely I'll revisit the suspension alternative
Shelf Material
I have tried so many different shelf materials, and some are better than others, but I feel like I am just spraying bullets that always miss the bulls-eye. So far, I cannot live with the brightness of glass, the ringing of marble or granite, the sluggishness of acrylic, the muddiness of mdf etc. Light and rigid seems better than heavy and dense - in that I can live with the downsides more easily. I use heavily constructed welded steel racks - spiked to the floor and upward spikes supporting the shelves - and I reckon this is right. I like the way bladder products get rid of the resonances that plague shelves, but find that the way they slow down the pace of the music is hard to accept. Does anyone have some answers on this?
