Which cone's or platforms have helped?

Bob, I have found in using the Sistrum products they work even more effectively when I remove all factory feet, rubber or any other material. I think the rubber slows down the extraction of resonance that Sistrum drains away so well. I wonder how the Nordost product could be effective when placed under a hunk of rubber. Seems there would be very unstable contact of dissimilar materials to provide any physical value at all. Please let us know more about your findings. Tom

Hi Tom I agree with you completely about placement under the footers, in theory I don't see how that could work very well at all.
Are you saying that although you bypassed the rubber factory footers (by placing cones directly in contact with the chassis) that the effect was still enhanced when the rubber footers were completely removed from the equipment? That is my perception of your explanation, & while it doesn't seem to me that would be of any significant consequence, if that is in fact your experience then I thank you for the worthwhile tip & I will try it out myself.

Bob bundus. What are the design differences between Nordost and Orchard Bay titanium? Just wondering what could cause the differences in sound. I found Titanium grade 5 is a harder version than grade 2 and may transmit vibration better.
Just a raw 1" dia x 12" long bar is $110 for grade 2 and $140 for grade 5. Guess I'll stick to brass for my experiment - 1" dia. will remove plastic/rubber feet and attach brass cones with screws directly to case where original feet were.
Also making a set for my speakers - 2" dia.

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.

Bob, Two competing theories- dampening vs resonance transfer.Besides believing in one and not the other, a person should not mix the two. If you do mix the two you have no reference point for either one. Yes when I removed all rubber from the bottoms of my equipment and used only the Audio Points or Sistrum Platforms it all got much better again. Quicker, quieter, lower noise, improved dynamics and focus. Less dampening brings you closer to the real thing. Let us all know...Tom
