Putting your best foot forward
Designers of vibration control devices constitute the unsung heroes of the audio industry. Unwanted vibration is a very real problem. No component can perform up to its full potential unless that problem is addressed. Many still assume that the issue is restricted to turntables and tubes. Unfortunately not. Solid-state electronics and CD players are also affected, often dramatically so. Additive and subtractive effects are numerous but all amount to the same thing. Your system is no longer reproducing the original signal. This is not what you want.

Over the years, simple and complex approaches have evolved. Better materials. Better thought-out designs. In this review, I am examining the top-of-the-line design from Weizhi Precision in Taiwan, their Gold Glory isolation feet. This company has attacked the problem with no-nonsense engineering to pack a lot of sonic innovation in a very small package. That very small package has the look and feel of a Rolls Royce. It also carries a price tag that demands it be taken serious. Who is Weizhi?

Weizhi Precision is located adjacent to the Hsinchu Scientific Industrial Park (Taiwan's Silicon Valley) where many high-tech manufacturers and design houses have settled in Hsinchu city of Taiwan. We are confident in our experience to work daily to an extreme degree on the various requirements which a highly competitive business environment presents.


Weizhi Precision has a twin focus in cultivating the semiconductor business and Hi-End audio. Our owner Mr. George Tsao has led the company since 2004. Henry Wang is our chief engineer with extensive professional experience in structural design and material applications. With both men devoting their special expertise to the hifi sector, music lovers are assured an even higher listening enjoyment. Therefore, Mr. George Tsao's slogan for our company has become Extreme Artistic Techno Sound Maker.


It drives our staff to create products where art and science meet with hi-tech know-how. Because we love music, we apply our musical enthusiasm to even the smallest tasks to make our high-end products successful. Our working experience in the hifi and semi-conductor manufacturing sectors combines with our mature knowledge of material applications to form the basic R&D concept from which we fashion our series of audio products.

We apply CAD/CAM graphics and 3D simulated tests; oversee material acquisitions, precision processing, sound adjustment, pure manual surface polishing and final quality control; and perform all these front-to-back processes at our Weizhi plant without outsourcing. We believe this vertical integration is the only way we can precisely control perfect production quality to assure excellent performance. Enjoy the music and your life.
