Yes, it matters.

If you want truly great performance from your music or home theater system, then you should know that what you place your components on makes the difference between good results and great results. Today's sensitive electronic equipment is more and more sensitive to the distortions which come from an unexpected source - mechanical vibration. Even subtle vibration will affect the quality of what you hear and what you see, and the better your components, the more important vibration control becomes. Vibration control represents the leading edge in state-of-the-art audio and video system technology, and for this reason, the equipment rack is a component which has become vital in determining the ultimate character and quality of a home theater or music system.

Why the Isis?

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. Click here for a full review of the Isis Rack system.

Exclusive Features

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.

Built-in Rollerblock isolation.

The Isis Rack features Symposium Rollerblock Isolation - not merely providing isolation of the shelf, but isolating the entire level (including the legs) from other levels while still maintaining a constant-density mechanical ground path (Patented). It is interesting to note that two of the requirements for proper component support - isolation and mechanical grounding - are seemingly contradictory: this is the essence of the solution that the Rollerblock Module provides.

"Svelte Shelf" Technology

Symposium's popular "Svelte Shelf" has been considered an essential component by audiophiles for years, an accessory device that some have called "compulsory." The Svelte Shelf's constrained-layer stainless steel sandwich construction provides lower distortion and a rarely heard, coloration-free neutrality. Every Isis level, whether a Standard (0.75" thick) Level or an Ultra (1.875" thick) Level, is supplied with 3 Precision Couplers, which provide exellent mechanical coupling between equipment chassis in order to make best use of the energy absorbing function of the Isis shelves.

Magnetic Bias technology

Magnetic Bias bearing technology keeps the bearings of the Rollerblock isolator units conveniently centered while lifting or changing levels, and also provides frictionless motional damping ("bias") which reduces bearing chatter, one of the causes of "bright," artificially "sweetened" sonics which can be heard with inferior ball bearing isolation feet.

Build-as-you-go Modular design

The Isis is a modular system- you can start with just one or two levels and build up to multiple levels at your own pace. Change shelf spacing, isolation options, or type and number of shelves now or later - even shelf size can be changed.

Lightning Rods for Mechanical Energy

The purpose of any rack's leg system should be to transmit energy to ground efficiently - this is called "Mechanical Grounding" and is essential for best bass performance. This pathway depends upon good mechanical conductivity - and the material makeup and design of the legs, often overlooked, is one of the keys to a rack's ultimate bass performance. Instead of the more commonly found legs which are made of wood, hollow tubing or steel, the Isis features solid legs of aircraft alloy aluminum - for unsurpassed mechanical grounding and sonic performance (aluminum posesses superior transmission efficiency to all other materials except silver or copper). The Isis offers quality you won't find elsewhere. Wood legs, or tubular metal legs, even if filled with sand or lead shot, cannot match the mechanical transmission capacity of the Isis' precision machined 1 7/8" diameter, solid aluminum leg sections.

EMI/RF "Faraday" shield design

Because of its shelf system construction, the Isis Rack system helps reduce distortion in sensitive components by providing RF/EMI shielding for your components. Multiple stainless steel layers form a "Faraday Shield" which reduces the harmful effects of EMI and RF, especially that which is generated by proximity to certain components, such as High Definition video receivers, which can emit higher amounts of EMI and RF energy. All current Isis levels have dedicated Ground Connection posts at the rear of each shelf for electrical connection between components and shelf, and/or shelf and a dedicated electrical ground.

Shelf and Finish options

Choose several different shelf options, including Standard or Ultra Levels. Isis shelves are precision laser-cut from polished stainless steel and are available in either 21x19 interior shelf size or optional "XL" (eXtended Length) 21" wide x 23" deep shelves for very deep components. Our most popular top level is the XT (eXtended Top) Top, which is 24" wide x 20" deep Xtended Top. The 21" x 19" size is also available for a top level is a smaller area is desired. Our "top of the line" top shelf is the 27" wide x 22" deep Turntable Top, which offers vertical isolation damping for best results with the finest analog turntables, digital transports, music servers or other critical components. You can choose from three leg and hardware finishes, including Deep Black Anodized, Natural Brushed aluminum, or premium, hand-polished Silver.

Shelf spacing flexibility

The modular nature of the Isis Rack allows for different component spacings determined by the leg lengths of each section, and "legsets" can be swapped out to change spacing if your spacing requirements change over time. For spacing combinations with standard legsets, please click here. If you need more space, or wish to tailor the total rack height to your particular needs, custom legsets of virtually any length are available on special order.

High energy transmission reversible leveling spikes

The interface between any rack and the floor is usually accomplished through adjustable spikes found at the bottom of each leg. Most don't give much though to this device - but in fact, the material used in the spike is critical, since it must have the fastest mechanical conductivity and efficiency possible. For this purpose, Symposium specified the second fastest metal on earth after silver, and Isis Rack leveling is accomplished through custom, heavy duty 1/2-20 Tellurium copper threaded bottom spikes. In addition, these unique spikes are reversible, with a machined flat side for hard floors, and a sharpened point side for carpets. Leveling is accomplished (even after the rack is fully loaded) by simply inserting a supplied tool through the spikes' orthogonal access holes - which makes it easy to turn the spikes under load. Locking nuts are premium brass.

"Real Engineering"

Webster's dictionary defines engineering as "the science concerned with putting scientific knowledge to practical uses." The audio art - and the art of home theater as well- is constantly advancing, and demanding new and better solutions, and even new and better science. And so, we seek the harmonious and efficient confluence of all of the requirements for the solution of a problem. Since the state-of-the-art is always re-inventing itself, state-of-the-art engineering must be equally as creative - for how else can we find new solutions for problems which were unheard of a generation ago? For this reason, while they may seem tenable upon first encountering them, relying on readily accessible solutions used in unrelated industries (automotive, industrial, military, etc), while easier, is neither adequate nor desirable for the specific and unique requirements demanded by high end audio and video systems, because the processes are different and not equivalent. For this reason, Symposium is committed to always seek the better solution, and make it available in our products regardless of its difficulty or expense.

Proudly Made In The U.S.A.

All Symposium products are designed and manufactured in the United States, with the great majority of parts and materials 100% made in the USA. We employ the best designs, materials, methods and local craftspeople in order to achieve our goal: to offer the highest quality product of its kind available.
