Hi-Fi Amplifiers Hi-Fi Preamps

Our designer Graham Slee has over 35 years experience in high fidelity amplifier and preamp design. Starting in the 1970's with disco and band amplifiers, through the late 1980's in broadcast audio, and the late 1990's on high-end hi-fi amplifiers.

In analogue signal processing you'll find our soon to be introduced high fidelity line stage preamplifier capable of more than just basic functions and very capable of producing a superb sound-stage along with true-to-life musicality.

We'll also be concentrating on "missing link" add-ons which many of our existing customers say they sorely miss - tone controls being one example.

It's equally good for high-end professional amplification having the features the sound engineer needs.
