The Marantz PM-10 incorporates switching power amplification described in more detail as follows:
"For the first time in Marantz history, the new flagship uses switching power amplification to deliver 200 watts RMS into an 8-ohm load, 400 into 4 ohms. Marantz eschews the designation of “Class D” for this amplifier because to many audiophiles that term always connotes a digital process, which simply isn’t true. The PA-10 is driven by a differential analog signal, a highly linear switching modulator operating at 450kHz. There are separate power supplies for the preamplifier section and for each of the power amp channels. With the goal of achieving the greatest possible noise rejection throughout the signal path, the topology is fully balanced from input to output. Line-level single-ended inputs are provided as well, though it’s hard to imagine many purchasers will be using them."
