The best of both worlds – extremely fast MOSFET driver circuits in Class A operation combined with enormously load-stable, power-potent “afterburners” in bipolar technology. This is the recipe for success for the particularly flat precision amplifiers, which, thanks to their sophisticated processor control, don’t get their feathers ruffled in any situation. Improved again and again over the years, these powerhouses with the characteristic, transparent enclosure covers have reached a sound level that is unrivalled, not only in the value-for-money category.
