Which cone's or platforms have helped?

Abruce, I really like the huge Mapleshade heavyfoots also and the price is very reasonable ($60 set of 3) for all that brass. I like them so much I am about to order some triple point heavyfoots to see if fully tweaked out version is even better.

I have not tried the Walker or Orchard Bay cone systems, but these Mapleshade heavyfoots were easily better than any previous cone I have tried.

Fiddler, if I go to local Home Depot I can buy various sheets of foam insulation that have different densities and thermal properties. Do you have a more detailed description of type of foam you used....color, density etc. Some are quite dense/stiff and some are much softer.

What were you previously using under gear? Are component feet resting on foam, or just underside of case?

I can add this to JD's bubble pack tweak and get it all with one trip to Home Depot, heh heh.

Trip to home depot at lunch shows that 4x8 sheets of polystyrene foam (for insullation) are two basic types:
-white foam, less dense softer foam
-pink foam, rigid dense foam

Got a sheet of the 1.5" pink foam @$13, thickness available are 1/2, 1, 1.5 inch (no 3" foam) The pink foam is preferred I believe, if you check the foam inside Nueance or
Symposium platforms it is closer to pink foam density. Cut some bricks 8 inch x 4 inch with razor knife to position under gear and avoid feet or any vents which must remain clear. The 1.5 thickness is good because it easliy clears existing feet without raising too much (I could double up bricks for 3" height)

I am happy with existing brass cones and bearings, but this is a cheap, easy thing to try for reference, although will not win any interior design awards.

I would like to see a picture of these Orchard Bay cones to see if they have any unusual features, search of the internet turns up nothing. Anyone have a web address to see these.

I just tried a pair of the Mapleshade triplepoint heavyfoot brass cones which are indeed slightly better in all respects vs standard heavyfoot. The standard Mapleshade heavyfoot was my previous cone of choice being better than any of the 3-4 other brands I have tried. The triplepoints are a little harder to correctly set-up initially, I used the two down, one up pattern to simplify installing under CDP. These are massive brass cones, Mapleshade contends the height and mass are necessary to acheive optimum sound vs other designs.

Have not tried Walker or Orchard Bay cones.
