A friend of mine drops me off component footers from time to time, he has an interest in them. I have always felt they can change the sound but not necessarily improve it. Last night I decided to try a few and see how it influences the sound, and perhaps give me some insights on what I want to do.
The first ones are an aluminum bullet with little bearings on the end that couple to a final plate. The second was a set of springs that are located between two layers of aluminum with machined holes to seat them. The third was a set of points that have a matching receiver plate that has a small cup for the tip of the point.
The springs sounded the best, but made the table inherently unstable. The points came in second and sounded pretty good, the bearings were my least favorite but still a solid sound.
The plinth has some challenges due to the front edge being thin, especially around the area where the control board resides. Some things would be done differently on a V2 version of this table. Also my son, doesn't quite grasp the level of minutia that audio people operate at. If I could do this, and had access to the tooling V2 would incorporate some changes. But the way it is now sounds excellent. Just the room I have to lay the footers out is less ideal than if I did a different version. Just the realities of taking on one of these kind of projects and relying on non audio people.
This seems to point to some kind of compliant feet in my estimation.
