Despite their high efficiency and low power consumption and heat generation, class-D amplifiers have long been relegated to second-class status by much of the audio community, appearing mostly in low-cost, low-performance audio products. (One notable exception is powered subwoofers, which require amplification only in a limited frequency range.) Lately, however, full-range class-D amps have gained more respectfor example, Pioneer has been using this technology in several generations of its Elite AVRs, including the 2011 SC-55 and flagship SC-57 reviewed exclusively on HomeTheater.com
Reviewer and long-time class-D detractor Michael Fremer was finally won over by the new Class D3 amp used in the SC-57 (shown above), but many audiophiles still scoff at this technology, preferring the sound of purely analog class-AB designs. What's your take? Have class-D amps finally achieved a performance level commensurate with class-AB?
