David,
"Cheaper" and "easy to make" both work for me :)I also like your idea of the levelling feet (mounted in the bottom layer of ply) better than the extendable ones, as I believe threaded spikes/cones need to be fully tightened to be most effective. I also like the idea of getting rid of any potentially "ringing" marble. I guess I was considering marble mainly because I thought lighter structures would resonate more readily than heavier ones.
I also felt that the platform layer directly under the component should have minimal contact with the layer below it (eg rest on cones rather than a full layer of polystyrene) to eliminate the possibility of changing its natural damping characteristic and "muddying" the sound. However, my thoughts were just that ...they were not based on any testing and listening ...yet.
However, you have actually done some listening and found this combination to work well. As soon as we move into the new house (mid Sept.) I will do the same. Meanwhile, your advice is saving me time building and testing unsuccessful or less successful platforms.
A few other questions on your setup ...
1) have you tried maple instead of ply (I understand that ply has some inherent multi layer damping benefits, but maple is used to make musical instruments) ? Perhaps a ply bottom layer and maple top layer may work well ?
2) have you experimented with the thickness of the layers of ply and polystyrene (is thicker ply and/or polystyrene any better ...more damping ???) ?
3) have you tried bubble wrap (small bubbles) instead of polystyrene ? Might it provide less surface contact and therefore a more neutral layer ...a semi air bearing effect ?
Thanks again David.
Cheers,
Darren.
