David Belles has been designing and manufacturing the finest sounding amplifiers and preamplifiers for over 30 years.

Power Modules products are among the finest audio components available, at prices that make high-end audio an attainable reality for most consumers.  All Power Modules products are state-of-the-art designs, using top quality components.  Each unit is hand assembled and tested to ensure it meets our high quality standards for fit, finish and audio performance.

We have designed several different components to meet a variety of power and budgetary requirements. From the 250 watt 350A power amplifier, to the less powerful, affordable 150A power amplifier, we have what you need. If you need an amplifier with more than 2-channels, then a 150A 3-channel version can be ordered, or even a 6-channel 350A! 

High quality components that reproduce the audio performance as accurately as possible. That's what Power Modules is all about. It's what David Belles has always been about.

The key to accurate audio reproduction is the ability to resolve detail.

To that end, David Belles has designed his first class A amplifier in 30 years. Everyone knows that class A biased amplifiers represent the pinnacle of what is possible in amplifier performance. However, designing and building a class A amplifier is no easy task.

The first amplifier that David Belles designed more than 30 years ago was an class A amplifier known as the Belles A.  Since that time, David Belles has learned what it takes to produce a truly great class A designed amplifier.
