The Power Plant Premier (Retail $2195), which PS Audio calls "the world's first and only low distortion, high efficiency AC power regenerator.
" The key part of this claim is "high efficiency." Earlier Power Plants consisted of a class-AB stereo amplifier with an efficiency of about 50%—which meant that they had to be very heavy if they were to output substantial amounts of power, hence current. The Premier's maximum output is 1500W; a Power Plant of the previous design that produced this much output would weigh about 200 lbs. Instead, it's a far more manageable 35 lbs. This is the result of a new amplifier design that's 85% efficient—but is not, as might be expected, class-D, which PS Audio determined would produce too much noise for this application. Instead, it's a development of the usual class-AB amplifier. What's special about it is a new tracking power supply designed by Bob Stadtherr, PS Audio's head of engineering, for which the company has received a patent. According to Paul McGowan, the concept of the tracking power-supply design is "elegantly simple, and its execution is breathtakingly complex to make it work."
