I understand Ted. I won't send them if you don't feel that they would fit your system. I subscribe to the theory of vibration ABSORPTION rather than transmission, unless it is a matter of infinite mass, like the Redpoint TT's. This is just the mechanical engineer in me I suppose.
I feel that any thing that rigidly couples a vibrating object to another, may reflect vibrations back, or if properly done, can transmit the vibrations to another source that will alleviate the mechanical energy. Sometimes I believe that what people ascribe as 'added energy' in their system with the use of certain cones, is simply vibration induced distortion, etc.
There is no one right approach obvioulsly. I do know however, that the Black Holes, on a rigid shelf, WILL very effectively absorb the vibration energy and give back significant sonic returns. I find the effect VERY apparent under my phono stage, which is probably one of the most sensitive pieces in my system.
Thanks,
