Gallo Ref 3 / 3.1 / 3.2 were all on spikes.
As part of the upgrade to Ref3.5 Anthony Gallo put the latest version on a soft polymer pad (not clear whether it is sorbothane) - concensus is that the end result is a noticeable improvement!!
The logic behind it still escapes me - but it may be that the absorption of negative vibrations ends up being a greater positive than the loss of ultimate stability - a compromise?
They say the base is made from Garolite which is a fibre glass and epoxy resin, with some Dermsol gel (what ever that is) applied to the base. Damn I was going to use resin and clay mix on my last speaker build and thought why bother. I did fill the bottom compartment with 20 kgs of sand though.
I've made 2 plinth using polyester resin and bentonite clay and its incredible how much vibration they suck up. The last one I made I used squash balls in between the plinth and some resin and clay cups as feet. I can tap the shelf and dont get any feed back with a stationary stylus on the record and the volume up high.
I also used 3mm Sorbothane in between the top and base plate on my scan dyna deck (standard plinth) to further isolate the 2, was getting a bit of vibration through, but none now. Its bolted together so there is a bit of pressure on the sorbathene.
