Origins
The Symposium Ultra Platform evolved from our first product, the SuperPlatform, and was created in an attempt to push the performance limits for a solid equipment platform further than had previously been possible. Experimentsand listening tests in many different types of systems indicated that those aspects of the Super which could directly benefit lay in the thickness of thefoam center section (which serves as a "heat sink" that converts mechanical energy to heat) and in additional constrain layering of the criticaltop layer. Also, a new, larger coupler was made which would provide more surface area contact between the Ultra's top and the equipment chassis.

Characteristics
The Ultra retains the following features of Symposium energy absorption construction:

Ordered constrained-layer construction
Superior energy dissipation with low reflection backto the component
Solid platform with no "bounce"
No leveling problems.
No leakage problems.
Virtuallyno weight limit.
Zero interaction problems with tuned suspensions of turntables.
Performance independent of its support structure
Ideal interface for Rollerblocks, cones, and most "footer devices."
Compatible on top of low frequency isolation devices

Compared to the Super Plus Platform, the standard Ultra Platform has 2 major distinctions:
Double thickness center "heatsink"
Banded center foam section

Anatomy
The Ultra consists of a multilayered design (right) of varying density materials. But what's different about Symposiumconstrained-layer construction is that we have arranged the density of these layers in a specific order, from dense (metal top) to less dense, and then backagain. The idea here is to gradually change density in steps, in the same direction, so that energy may penetrate more easily through adjacent layers. Thisunique but essentially simple design achieves optimal energy drainage from both the component side AND the support (bottom) side at the same time. This"dual direction" absorption provides effective isolation without eliminating the advantages of good energy drainage, and does it withoutintroducing any mechanical "reactances" which are caused by materials which store and release energy, such as sorbothane and other rubber products.Instead of behaving like a reactive load, the design is more resistive, which means it is resonance-free, adding no colorations to the component's sonic"character" in attaining its goal of reducing noise and distortions in the components it treats.
