Can a $199 amplifier really scare a $10,000 high-end monster? Class D has been called the "witch doctor" of the audio industry for years: sand in the highs, hysteresis in filters, transistor problems, "digital" sound... But what if most of these problems have long been solved, and the market simply hasn't caught up with reality? In this video, practicing engineer Guntars explains why Class D is destroying the traditional high-end amplifier business. We'll explore: the historical myths and real technical problems of Class D; how modern chips, drivers, and specialized transistors have solved them; what Bruno Putzeys, Hypex, IcePower, and other developers have done; why the TPA3255 chip and Chinese modules based on it are so dangerous for classic amplifiers; analogies with Kodak and Nokia – when the market didn't believe in a new technology and lost out. We'll talk about output filters, gate drivers, inductors, distortion with three decimal points, and why creating good Class D is more difficult than classic A/AB—but the results are worth it. Let's talk in the comments whether you're on the side of heavy, hot high-end or compact and efficient Class D. And, of course, check out PremiumHIFI for amplifiers, headphones, and honest discussions about sound. 📍 Demo Room: https://maps.app.goo.gl/3ms6YBRarrZbR...
