Mapleshade uses two, glued double decker but crossways, for heavier units, and the same but cut into 2" blocks for lighter units. If you do the math you'll see their mark up is only normal amount necessary bring anything to market. It is a testimony to Pierre's commitment to offer real world improvements for reasonable cost, that he goes to the trouble of exhaustively researching cost effective tweeks that work and marketing them for the benefit of you and me. It is also a testimony that he believes in his products that he offers a 30 day money back guarantee. He is also VERY generous with his time helping folks on the phone. Projecting cynicism on him and others like him is unfortunate, unnecessary.
Dealer disclaimer.
On a slightly different note. There are two different issues with vibration control. One is to isolate components from externally generated vibrations such as airborn music sourced vibrations and foot falls with turntables. The other is evacuating subtle vibrations generated within the components by the circuitry itself as well as any vibes taken in from the outside. Many people believe that the priority is to evacuate with rigid cones rather than isolate with soft material and that the latter traps vibrations within the component, muddying the sound. The ideal seems to be a combination of evacuating with brass cones such as the Mapleshade Heavyfeet or Walker Valid Points, into a massive platform such as hardwood or granite, etc. which in turn is suspended by soft material such as sorbothane, the above mentioned Isoblocks, or a sand box arrangement such as Brightstar offers. This effectively evacuates, dissipates and isolates and can be quite affordable. At the least, experimenting with cones will yield surprising results if you've never tried them. There seems to be an advantage in bigger cones, thus the Mapleshade Mega Mounts.
