His exploration of technologies, driven by his never-endingquest to elevate the standard of excellence, has resulted in break- through audio designs. Over the years, the Krell line of power amplifiers, including benchmark products such as the KRS -100,KRS -200,and the Audio Standard models, has established a legacy of unparalleled sonic performance.
