A Tombstone in the Living room????

O.K. Joe, I'll bite.
You state,
"Using their unique understanding of resonance and how it effects all components, including loudspeakers, made logical sense to me. They stated that permitting resonance to form on equipment then immediately directing energy (vibration) away from the components and transferring it to earth's ground (a basic physics approach) using raw materials that "conduct" resonance permits the DYNAMICS to remain within the system.

They further went on to say that brass, steel (cold rolled) and aluminum are materials that will conduct resonance. Some work faster than others do.

When I asked about the granites of the world they went on to state that rock's principle material is earth itself. It fools the resonance into thinking there is a true earth's ground. When applying this type of material with acoustical and electronic products try to maintain a good distance between your components chassis plane and these elements, because earth too will absorb energies along with precious dynamics as well."

My reason for pasting this set of three pharagraphs is two fold. First are you not conterdicting yourself? Second,
"transferring it to earth's ground ..." and then "...rock's principle material is earth itself. " It seams to me my sandstone set on a stone hearth set on masonry set on earth would also qualify as "Earth". Now you tell me to drain this energy to earth but keep earth away. Fine, I would then assume the brass, titanium, and carbon fiber cone products I use to seperate my equipment from the stone would qualify as your "resonance conductors". What did I miss here? sounds like I must have solved the issue for the price of cones. J.D.

Wow,this is getting heavy!(no pun intended) Anyway, my tombstone is under my Pass.I cleaned some old bird doo off it then painted it gloss black.I put some thin spongy material on my DIY amp stand then the granite on the stand.My bass is a bit tighter.Thats all the effect I hear.Still for $20 was well worth it. R.I.P.

Plane Old Joe- I want to start by saying that I have no idea how this product sounds, and that I hope that this product works for you. However, I have to say (IMO) that the description you quoted makes some the "creation science" arguements I have read seem downright plausible. It sounds like someone let the marketing department loose with a new ager and an electricians handbook. I don't know anything about acoustic treatment and shelving, but I know enough to recognize pseudo-scientific BS when I see it. Just my $0.02.

Just a remark from a latecomer in the Tombstones discussion. Much of the junk found in graveyards (RIP)are MARBLE and IMO, marble does NOT work the same way as marble --- granite is invariably better, especially under heavy components eg, power amps, or equipment that's by nature ultra sensitive to vibration (eg, TT). I use granite for both. Marble sounded muddled, worse than mdf, on my system.

I find that stones are OK to very good if placed under turntables or speakers, or under equipment racks, but are not good as shelves for CDPs, DACs, Preamps or Amps. They all "ping" to some degree and you can hear it with electronic components, and they also store energy and release it slowly thereby creating a smearing of detail. The stones all sound different, and different marble sounds different depending on the level of impurity (more impurity sounds better). Thick acrylic sounds better than most stone, but suffers much of the same problem. Maple Butchers Block is better again, but being picky, images are enlarged and flattened, leading edges are slowed (as Brulee says), and there is a slight lack of presence (related to the flattening of images) - but if stone is 5 out of ten, then Maple is 8 out of ten. But do try stones under your speakers, particularly if you have a wooden floor - but granite is probably the worst sounding of them - others like soapstone, impure marble or sandstone sound better.
