stacked equipment isolation?

Hi Uncertainsmile,

Any rigid material or device will not provide isolation. The result of using a rigid material or device is to allow unwanted floor-borne vibration to travel up through the rack and directly into the equipment. In addition, chassis resonances due to air-borne and internally-generated vibration will be able to travel from component to component within the stack.

The only way to effectively and comprehensively address this problem is to decouple your stack of components from the floor-borne vibration and from each other. In addition, you must also provide a method to convert the destructive mechanical energy into benign thermal energy.

Some companies claim to "drain" vibration away from the equipment through some type of coupling but they have never provided any independent laboratory measurements to prove that claim. They also ignore the fact that a rigid device allows vibration to travel not only in one direction, but also in BOTH directions - up from the floor and down out of the equipment. In addition, any device that allows vibration to affect the signal flowing through the component and then attempts to drain the vibration after the fact can never restore the signal to its original, pristine condition.

We manufacture many highly effective and very affordable products that will suit your needs. You can see them at: LINK

Hi Uncertainsmile,

The least expensive but still quite effective recommendation would be to use our IsoNode feet under the bottom component and between each successive component. The IsoNode feet are one of the most cost-effective upgrades you can make. They are extremely affordable. We manufacture them in two sizes:

The small size (3/4" by 3/8” high) are just $12.50 for a set of four feet! The set of four feet holds a maximum of 30 lbs and includes adhesive backing.

The large size (1 1/2” by 3/4” high) are just $19.99 for a set of four feet! The set of four feet holds a maximum of 42 lbs and includes adhesive backing.

We offer FREE SHIPPING to the United States or Canada for either size.

The IsoNode feet have been voted:

PRODUCT OF THE YEAR by Enjoy The Music

BEST OF CES by Audio/Video Forum

and were included in The Stereo Times’ and PC World’s Holiday Gift Guides.

We currently have a special promotion for Audiogon members: You can try the IsoNode feet in your own system FOR FREE. Please click HERE for details.

We have many of our other products available factory direct HERE

The next level I would recommend would be to use our IsoRock 4 platforms in the same manner. They are $139.00 each. If your component exceeds the maximum load weight for the platform you can easily add extra IsoNode feet as required to hold the weight. If your budget and space allow for it, I would recommend a Little Rock pod placed on the top component.

The best option is, of course, the most expensive and also requires the most vertical space within the rack. This would be one of our Ultimate Isolation Systems which consists of an Air Mass / Big Rock / Little Rock combination. The least expensive Ultimate Isolation System is $399 and the most expensive is our Reference Series at $2100.00. The Little Rock 2 can also be stacked between components.

Bright Star Audio has more products listed in Stereophile’s Recommended Components than any other accessories manufacturer. We have also received dozens of industry awards and nominations for our products from a large number of audio publications around the world including four times for "Accessory of the Year" by Sterophile, "Best of the Year", "Best Buy" and "Editor's Choice" by The Abso!ute Sound, five times "Component of Merit" award from Bound for Sound, three times "Golden Note Award" from The Academy, just to name a few!

Ours are the most comprehensive vibration control products available. They are designed to address ALL of the sources and forms of vibration: Floor-borne, air-borne, and internally generated. Our philosophy is to eliminate vibration BEFORE it contaminates the signal flowing through the component. Our products DO NOT try to manipulate the vibration or resonance after it has been allowed to contaminate the signal. Our products also DO NOT "tune" resonance (a very misguided concept). An audio system IS NOT a musical instrument. To faithfully reproduce the sound of the instrument as it has been captured in the recording, the playback system must be as free of unwanted extra contributions and artifacts as possible.
