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

I was recently challenged by a friend who is a Sistrum Platform non believer to measure in room response of a system consisting of Thiel CS6's Krell amp and pre and Krell cd. All of this sat on a Stand Design audio rack. I used Audiocontrol RTA and calibrated mic as my tools. Using pink noise and taking spl measurement set at 80db. Variation in actual spl measured between 79 and 81.5 db. I did not at first realize this variation was caused by the compression and expansion of the room itself. WE then took frequency response measurements at the same level and recorded these and stored them to the rta. Step two was to add the Sistrum Platform under the Krell CD player and to repeat the same test in the same identical manner as the first. The SPL measurement shocked me! The variation in SPL was less and also flucuated at a slower rate. I really thought the spl would increase with the addition of the platform because I could always hear much improved dynamics with the use of Sistrum products. Next we took frequency response measurements and stored these as well. Upon comparison of the 2 curves my friend and I both could see marked improvement in the lower mid bass to mid range shape as well as the range from about 3k on up. This improved curve was now more of a flat line with the use of the Sistrum Platform. This was the first time I had ever measured a system with and without the platforms. I really did not think that all the improvements I knew I have been hearing with the platforms could actually be measured so easily. My friend stated he thought the reduction in spl related to less distortion when using the Sistrum platform. This was my perception when listening with these devices in place. More detail and separation, much lower noise floor and much greater contrast. Let me state I do not make it a habit to walk around with an RTA taking measurements of my system or anyone else's. The texture of the music is the turn on for me. I did however thank my friend for the Sistrum challenge.

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

Hello,Its hard to get your hands around a soup sandwich. Mixing shelves of different thickness and different woods with rubber pucks and points of steel with those of carbon fiber or titanium, brass or lead, sitting on grandmoms girdle between two layers of bubble wrap is not the scientific approach. How can you possibly know which one of these materials is the right one when they are so thrown together? How can you know which of these shapes is the right one when they are so thrown together. There are products out there with a single approach that work for me. However this one single means, has me using all the same theories based on actual physics with the same materials and same ratio's thruout. This single focused approach has made it all so apparent that the science of resonance transfer truly works. Once you hear these devices and how they perform so well and understand how they really work, a light bulb will turn on in your head and you will suddenly say that makes so much sense! Once you start down this one lane road you will be able to predict the nature of improvement for each new point, platform or rack that you add to your system. This approach becomes cumlative in nature and the sonic improvement continues resulting with the same, consistently huge, dynamically focused soundstage. There is no turning back!
