Walk into a mastering studio anywhere in the world and the amps powering the monitoring system are likely to employ linear forms of amplification (Class A & Class A/B). Are these amps more widely used because they're the best option? Class D amps have staggeringly low distortion and are currently the most efficient amps you can buy, so why are they not more often utilized?
To find out I spoke with Bruno Putzeys of Hypex Electronics in The Netherlands. Bruno has worked as an amp designer for decades, beginning his career with Phillips before moving his innovative Class D design to Hypex. Bruno how Class D amps differ from traditional linear amplifiers, why some amp designers don't take advantage of rational engineering principles, and why it's so hard to make a 'green' amp that sounds good.
