Essence Electrostatic has just released their new DPA-440 Class D stereo amplifier that produces up to 220 Wpc @ 4 Ohms. The new Essence DPA-440 has a low signal-to-noise level of -100dB and high dampening factor of <1000, with up to 40 Amps of driving power.
Leveraging the latest Class D topology, the DPA-440 is a highly efficient amplifier with very low distortion combined with very high stability to proficiently drive almost any speaker load. The all-discrete driver and output stage have lower open-loop THD as well as lower idling losses. The amplifier is claimed to be able of providing up to 400 Watts of dynamic power per channel @ 2 Ohms.
The performance of the entire signal path is critically dependent on the power supply; in this case a well regulated switch mode design with 90% efficiency. Secondary supplies are individually regulated and decoupled at each OpAmp for lowest possible noise and maximum dynamic range.
