Suitable for use as dedicated platforms or as replacement shelves in existing racks and stands, Symposium platforms allow you to realize optimum performance from your audio and video components by draining and dissipating mechanical energy without unwanted resonances. Symposium platforms also make the perfect companion to Rollerblock systems.
Although Svelte Shelf's most noticeable feature is its attractive, slim design (hence the name "Svelte," meaning slim or slender), the fact is, it's not just a shelf, but a sophisticated, anti-resonant platform for the support of high quality audio and video components. Placed under CD Players, DVD players, amps, preamps, speakers and more, Symposium's Svelte Shelf will improve the performance of your system without changing its inherent tonal character. Prior to its introduction, equivalent performance required much greater thickness and mass. The Svelte Shelf's design is simple, but effective. Now, even the most vertically-space-challenged rack or stand can benefit from Symposium vibration control. The Svelte Shelf works well on most surfaces; it can be placed flat on an existing shelf or floor, or substituted for an existing shelf by ordering an exact size replacement.
The Svelte Plus is an expanded version of the Svelte Shelf, with a center foam section twice as thick as the center foam section of the standard Svelte Shelf. In addition, the foam section of the Svelte Plus is protected by textured vinyl edgebanding, similar to that found on the Ultra Platform. Including its polished stainless steel top and bottom, total thickness is approximately 1.125 inches or 2.9 cm. A more affordable alternative to the Super Plus and Ultra Platforms, the Svelte Plus is a synergistic combination with hard equipment footers and a perfect interface for Symposium Rollerblocks. Doubling the internal foam section increases damping power, isolation effectiveness and rigidity, and allows further benefits in transient preservation, microdynamics, timber resolution and top-to-bottom musicality.
Super Plus Platform
Symposium designed the Super Platform to satisfy the problems and requirements of equipment support from a perspective which takes into consideration not only isolation, but also energy drainage out of equipment. The original Super Platform was the first dedicated equipment base to use symmetrical constrained layer damping with metal top and bottom layers.
The Symposium Ultra Platform evolved from our first product, the Super Platform, and was created in an attempt to push the performance limits for a solid equipment platform further than had previously been possible. Experiments and listening tests in many different types of systems indicated that those aspects of the Super which could directly benefit lay in the thickness of the foam center section (which serves as a "heat sink" that converts mechanical energy to heat) and in additional constrain layering of the critical top layer. Also, a new, larger coupler was made which would provide more surface area contact between the Ultra's top and the equipment chassis.
The Quantum embodies an accumulation of all that Symposium has learned about the effective coupling and damping of electronic components in a dedicated platform. The Quantum spares nothing in the quest for ultimate performance. Utilizing stainless steel technology borrowed from the very successful Svelte Shelf and "expanding the envelope" to the very limits of practicality and design, the Quantum is the last word in neutrality, nuance, dynamics and transient preservation.
Ball-bearing isolation devices can make improvements in system performance unmatched by other isolation devices. SYMPOSIUM introduced the bearing isolation device for active components with the original ROLLERBLOCK in 1997. Constantly improved since then, we make the finest bearing isolation devices anywhere - because when it comes to bearing isolation for audio and video, we wrote the book.
Rollerblock Series 2+
Symposium Rollerblock Series 2+ is an equipment support system providing simultaneous coupling and decoupling of audio and video equipment. When properly installed, a set of Rollerblocks can increase overall system performance by an order of magnitude similar to a wholesale upgrade of the component it treats. Utilizing technology employed in earthquake protection and combining it with proprietary mechanical transmission techniques, Rollerblocks are the most sonically beneficial coupling devices available. Used beneath digital equipment, DVD players, preamplifiers and other components, results can be nothing less than astonishing. Increased focus, soundstaging, image stability, dynamics and delicacy are just a few of the sonic delights awaiting the serious audiophile. When used with an effective equipment base (such as Symposium Platforms), the Series 2+ Rollerblock system provides an additional step toward ideal equipment support, which is simultaneous component isolation and drainage of chassis-borne vibration. Symposium Rollerblock Series 2+ systems achieve their seemingly "magical" results by obeying laws of physics. Their strict manufacturing tolerances (much higher than usually found in an audiophile "tweak" device) are responsible for their world-wide reputation as the best ball-bearing isolation device available. Professional reviewers and private owners alike have spoken emphatically about the ability of Rollerblocks to enhance and improve the performance of virtually any component, including CD players, DVD players, digital transports, preamplifiers, amplifiers, and more.
Symposium introduced lateral ball bearing isolation with the original Rollerblock® in 1997; since then, Symposium's Rollerblock® Series 2 has been the standard of excellence for ball bearing isolation in the high end audio industry. Many rave reviews and customer comments reinforced their position as the premier ball bearing isolation device. However, it became evident that there was a need for a lower cost "introductory" ball bearing isolation device designed with the same audio expertise and commitment to quality as the original Rollerblock. Thus, Rollerblock Jr. became a reality.
POINT PODS, FAT PADZ, and COUPLERS
Stationary footer devices which work independently or in conjunction with Symposium platforms.
The Point Pod is a very slim, "mini" Symposium platform- only 2" by 3" small (5 x 7.6 cm), and only 1/3" (0.84 cm) thick. Their tops and bottoms are layers of hand finished, polished stainless steel, and their interior consists of 3 constrained layers, including a 3/16" (0.5 cm) thick foam center section. Point Pods are ideal for use with small active components, such as mini-digital processors and power supplies, or with loudspeakers. They are also ideal for use with an inverted Rollerblock setup, as their stainless steel tops are hard enough for direct contact with the Rollerblock ball. Point Pods are most effective when used in direct contact with the chassis of components. In this primary application, they are effective either beneath or on top of the component, or both. They are also excellent for use when larger or taller isolation devices aren't appropriate or practical, as in equipment racks with limited vertical space. They are ideal for use on wood floors to protect spikes and cones from damaging surfaces, and can be used together with Symposium Large Couplers and Rollerblocks to improve overall sonic results by providing a more neutral support surface. Point Pods are very effective with loudspeakers; in this application, they improve sonics by damping cabinet wall vibrations which cause loudspeaker driver intermodulation distortion.
Fat Padz are stand-alone, vibration-absorbing devices which provide effective, "problem-free" resonance control and vibration damping with active and passive components. Compared to conventional cone-type isolation devices, Fat Padz are more tonally neutral, and more effective at reducing distortion, since they have the ability to dissipate energy as well as reduce the amount of new energy that can be introduced into the component from its support surface. They are more convenient and somewhat safer to use than cones, since they are physically more stable and cannot topple over. The Fat Pad is a mini Symposium platform- only 2" by 3" (5 x 7.6 cm), and 7/8" thick (2.2 cm) with tops and bottoms that are layers of precision laser-cut, polished stainless steel. Their interior consists of 3 constrained layers, including a 3/4" (1.9 cm) thick foam center section banded with textured vinyl edgebanding. The foam section is the same thickness as the Super Plus Platform. A Fat Pad can be considered an "expanded" Point Pod, since it is identical save for its thicker, banded foam center.
Symposium's new Precision Coupler replaces our former Large Coupler to provide superior performance and convenience. Made of top-grade 7075 aircraft aluminum and precision machined to scintillating surface finishes, Precision Couplers are used to form an efficient mechanical connection to the components placed upon Symposium Platforms and Isis Rack levels, for effective damping of internal equipment resonances - an essential requirement for best results with vibration control devices. The high mechanical transmission efficiency of the aluminum alloy also provides an excellent transmission path for the evacuation of mechanical energy out of components and into a mechanical ground, where it can be absorbed and/or converted to heat energy. Each Precision Coupler features nearly perfectly parallel top and bottom surfaces, and one side has a threaded 1/4-20 hole for attachment to many existing foot posts or for screwing two Precision Couplers together to form one high coupler to clear very high feet. Each Coupler is 0.8125 inches high (13/16" or 2.06 cm) and 1.875" (4.76 cm) in diameter.
Designed to interface optimally with Symposium platforms and Rollerblocks for top performance from today's electronics, the Precision Rack is made to your specification and has virtually no weight limits. The Isis Rack is an innovative, modular and expandable state-of-the-art support system for audio and video equipment.
The Precision Rack
The Precision Rack is a "no holds barred" attempt to make the best support structure possible for our shelves. Instead of using more common construction techniques, using wood, or hollow metal tubes, the Precision Rack is made from solid rectangular bars of aircraft grade aluminum, precision cut, machined, and beautifully hand-polished. We have heard the opinion that a rack isn't important- that the shelves, the footer devices, and those things that actually and directly contact the component are the only things that matter. Although we would agree that these have the most profound influence on the vibration treatment of the component in question, the support structure is also important, and for several reasons. The rack, or frame, should be rigid and have excellent energy drainage characteristics, and the frame should be damped to discourage resonance. As we stress in the description and design of our platforms, energy drainage is of primary importance in the grand scheme of vibration control and isolation. Without it, energy remains trapped in the active circuitry to cause more signal distortion (spikes and cones function on this principle). Racks and stands which provide stopgap "isolation" schemes (with, for instance, rubber air balloons or sorbothane motor mounts), then disregard the drainage or sonic signature of the actual shelf, are making a bad problem worse. We have found, after years of experimentation and research, that the battle for vibration control is fought and won at the component itself. That is, the closer to the component you provide proper damping and isolation, the better will be the ultimate result. Whatever energy is left over should be conducted to ground as efficiently as possible. The rack, therefore, should be like a cone or spike- rigid and dense in order to provide for proper grounding of mechanical energy.
The Isis Rack
The patented Isis Rack fulfills the goals which any equipment rack should strive for - acoustic neutrality, simplicity of design, excellent energy drainage and dissipation, isolation from floor borne vibration, and an optimal mechanical ground path. The design goal of the "perfect" equipment rack has been addressed by the Isis Rack in a modular solution that offers the convenience of being expandable at any time to accommodate additional components.
The Isis Rack combines two innovative technologies pioneered by Symposium: the Svelte Shelf and the Rollerblock isolation system. The combination makes for a startling advance in rack technology.
