When I first heard the word "audiophile," I loved it. It sounded fresh and dignified. I related to it instantly. An audiophile! I loved the whole idea of it, the focus on music, on sound. That was me! I'd found myself! And people like me. Other audiophiles, who lived all over the world. To paraphrase Tom Petty, it was like a first flash of freedom.

Talk about a Scarlet Letter. The term class-D amplification, which describes PS Audio's new M1200 monoblocks, exists only because another amplifier innovation had already parked in the "C" space. Soon after appearing in high-performance audio gear, class-D became synonymous with "digital amplification" in part because, like early CDs, many listeners found the sound glary, hard, and unpleasant. Besides, class-D is related to "pulse width modulation" and requires a low-pass filter to block high-frequency pulses—that sure sounds digital. But they're not (see Bruno Putzeys sidebar).
