Walker Audio "Standard" Valid Points Resonance Control System The Standard Valid Points kit consists of three brass and lead alloy cones and five resonance control discs. The cones are placed under the component, point down into three resonance discs, isolating the component from the shelf and draining energy into the discs. The other two discs are placed on top of the component to control the case resonances. (3) Cones - (5) 1/2" Resonance Control Discs

As taken from Lloyd Walker...

I've tried every kind of vibration control device I could

obtain - aluminum, brass, wood, ceramics, compound applications of cones and absorption material. Some helped; some ruined the sound. None went far enough to stabilize, isolate and control the resonances of the components.

 No system can sound its best until resonances are under control. To achieve the "magic" that your system is capable of, resonance control is a must.

Through extensive experimentation, we discovered that stands, shelves and the enclosure of a component are major contributors to vibrations. Manufacturers design their enclosures for appearance, convenience and cost reasons, with little or no attention to vibration control.

Many materials that are commonly used to to manufacture shelves and racks, such as marble, granite, glass and most metals, actually aggravate the vibration and resonance problems.

My quest for the ultimate sound led me to create Valid Points which are designed to provide isolation and to stabilize and control resonances of all components in an audio or video system. This includes analog, digital and video components, as well as speakers, shelves and stands.

WHERE TO START

We have found that resonance between components can be additive or subtractive. Therefore, it is necessary for the two most critical components to be treated first, at the same time. Here are the most critical components for each system type.

v Analog:  The turntable (if possible) and 

pre-amp or phono amp and pre-amp

v Digital:   The transport or CD player and pre-amp

v Video:    The video player and processor

WHAT'S NEXT
Amplifiers and remote power supplies are the next most critical components, followed by D-to-A converters, active crossovers, shelves, racks and speakers.

WHAT TO EXPECT
The improvement in the sound will be amazing. The sound stage will have greater width, depth, detail, bass, speed, extension, and focus.
