Closing the UK company

In December 2006, the board decided to close the business and a buyer was sought for the IP, stock and assets. The investors cited "investment in Global Silicon was written off following its failure to get significant sales traction despite having a proven product". It is also self-evident that the loss of the company's Chairman, William Jeffrey due to cancerThe Times
will have factored in the decision process. The timing of the closure was also at a pivotal point in the consumer audio market, with

equipment sales falling and being replaced with products such as the
