I have and I strongly suggest to mechanically direct couple all internal major parts of an audio component. Nothing is decoupled in my power amps. These parts include transformers and any all filter caps that are chassis mounted. I have direct coupled the 4lb copper heat sink that stands vertically and has attached the 2 power mosfets which is then bolted to the bottom plate of the chassis. The main circuit assembly is mounted to our Sound Works platform and tensioned thru the board and out thru the chassis frame below and secured.. All of these parts reside on Audio Points and our coupling discs and must be secured and clamped into place for maximum audio performance and safety concerns. I had cut and drilled brass cylinders that mount near the non existent corners to which the top and bottom plates are tensioned. The whole component is then mounted externally to one of our Sistrum or Rhythm Platforms with our points which face north to the 3 tensioned internal connecting rods.. This was certainly an exercise of will but the payoff is high... and wall to wall tall, with resolution that extends past my listening chair. The endeavor was to make all the internal vibration go in one primary direction..to ground. To do this, like geometry and materials are required to maintain speed and operational efficiency. Tom
I realize I’ve probably asked you this question before but now that you’ve taken case of the vibrations produced by motors, transformers, etc. In the component and vibrations that might wind up there due to acoustic forces how did you address the seismic vibrations? It appears you’re ignoring them. Maybe you are thinking the seismic vibrations go up and are are taken back down by the Audio Points, or perhaps you believe the Audio Points disallow seismic vibrations from being transmitted up to the component, who knows? Am I missing something? I hate to judge before all the facts are in but you guys appear to be behaving like the proverbial ostrich with his head in the sand. It may very well have been an "exercise of will" but apparently you willed the whole seismic isolation argument away with a wave of your hand. Speaking of which whatever happened to your seismic waves?
