In His Youth

John Cheadle was born and raised in Birmingham, England. As a boy John was always interested in electronics, and radio in particular. He built up a collection of all sorts of ham radio equipment, and self-studied to a level where he was able to carry out significant repairs to his equipment. This led to him working in a satellite receiver repair company for a few years. At the same time he became a huge music fan, with a significant album collection of all sorts of modern music genres.

After moving around the country for quite a few years, he settled in Llandrindod Wells in the very quiet county of Powys, right in the centre of Wales. This is where he then spent many years working for Roksan (until they moved to London). Whilst at Roksan, John designed all the early products in the Xerxes range. In particular, his designs for turntable power supplies and phono stages were very successful.

The Vertex Years

Then in the late 1990s, John started working with Steve on the development of Vertex AQ, and through the lifetime of the company so far, he has led in the following areas:

  • The development of unusual production techniques that effectively incorporate the company’s RFI/EMI and anti-microphony techniques into reliable and robust products that consistently deliver performance to every Vertex customer. Having great ideas within a company is one thing, but being able to continually deliver the products over years to the same high standard is pivotal to the longevity of any company. Our return rate across the board runs at 0.5%, and of those returns 80% of faults have been caused by misuse (usually conductors or connectors broken when cables are stood on!).
  • The continual following of design developments within the high-end audio industry. The vertex products are not designed without deep knowledge of the way all elements of a hi-fi works. And as we specialise in things like mains conditioning, the development of switch mode power supplies for example, is an important factor. The same goes for the split in trends for either simple NOSDAC strategy, or complex 24 bit technology – continual studying, testing and listening is essential to understand the issues of these very different approaches.
