<span><span>New electronics bearing the Mark Levinson badge don’t appear too often. When they do, the world of high-end audio expects them to be exemplary. In producing its first switching amplifier, the ML design team has been able to scale things down to (almost) manageable proportions. The benefits of Class D amplifiers include increased efficiency enabling greater power output while requiring less heat dissipation in smaller, lighter and more affordable packages.<br />
** It may seem laughable, then, that ML’s first foray into designing a switching amplifier should result in a massively imposing monoblock 53cm tall and almost as deep, and weighing 62kg. But considering its power output and compared to the No33 it replaces, the No53 may be seen as <i>relatively</i> compact.<br />
** The No53 is not a digital Class D amplifier but employs a new take on Class D switching amplifier design using a proprietary methodology dubbed Interleaved Power Technology (IPT). This is said to eliminate ‘dead bands’ and move switching noise to beyond audibility by raising the switching frequency. It uses a massive linear power supply featuring a 2.8kVA toroidal transformer with four 47,000
