Hello,
I have some experience in building, DIY, isolation platform using a pair of 1 inch thick maple plywood and springs. I selected the springs with lowest possible spring rate for a given load such that the natural/resonance frequency of the unit dips down to 5hz or below. I encountered three issues with the platforms
1. Levelling components having asymmetrical load distribution. In order to get the maximum isolation benefit I needed to equally distribute the load to each spring such that each carries a load very close to its max load bearing capacity. With asymmetrical load distribution this was very difficult and I can see this as a key issue with MK, Vibraplane, Townshend or any such isolation platform.
2. The combination of steel and wood platform was adding some colour to the sound output that I didn't like. I hope the platforms used in these commercially manufacturered products is very neutral.
3. Cables specially thick aftermarket cables attached to the components degrade performance by adding more than required damping and compromising the freedom of movement of the platform.
Did you guys face any of the above issues with your platforms?
