About us

Established in 1998, Graham Slee Projects Limited headquarters and main workshop are located in Monk Bretton in the county of Yorkshire in Great Britain. It also has a branch workshop in South Anston in the Rother Valley.

I moved to Monk Bretton in 2000 shortly after establishing Graham Slee Projects with the launch of my first commercial phono preamp, which was warmly greeted in a review by the UK Gramophone magazine.

My background is in engineering - apprentice and college trained in heavy engineering during the 1970's, then moving into audio-visual and DJ work, electronics and printed circuit design, and reaching a career high point of senior engineer in a broadcast-audio company in 1989. I also worked freelance in R&D with UK Hi-Fi and touring band amplifier manufacturers.

I have two co-directors: one is my wife Diane, the other is John Cadman who I met whilst a senior engineer in broadcast audio. He is highly experienced and disciplined in the manufacture and test of high quality broadcast audio equipment and brings those standards to our products.

The third engineer is Leon who is also highly qualified and was test room engineer at Carlsboro Sound.

Between us we design manufacture and test our great products at our locations in Yorkshire and the north midlands of England UK.

In addition to quality workmanship and our careful selection of great-sounding components we insist on proper testing and measurement at the design stage and at 100% during manufacture. Rather than using cheap computer audio test gadgets (computer tested often means short cuts have been taken), we use recognised high precision analysers as used in broadcast and communications. We also have electrical safety test equipment capable of flash testing to 3kV. The costs involved are formidable but we feel you, the customer, are worth the investment.

Our products are truly high-end in that they deliver much more in musical enjoyment than many other brands, but at much more reasonable prices considering they're built by true professional British engineers. We are enthusiasts doing our best to please other enthusiasts.

Graham Slee Projects Limited is engaged in continuous product development to ensure its customers obtain the maximum in musical satisfaction. Upgrades are made available at reasonable prices for customers wanting the benefit of our latest discoveries.

In 2011 the brand name Graham Slee was registered as a UK and European trademark.

We hope you enjoyed our "cottage industry" factory tour and after reading our story you realise just how committed we are to bringing you the very best in reliable high quality - high performance audio products.

This is me getting to the "bones" of a design on our powerful SPICE simulator. It's not just for new designs, it is often used along with our state of the art analytical test equipment in ensuring our existing products are performing to the highest expectations of our customers.
