Product details
PURIFI 1ET400A | Eigentakt | Amplifier Module
This high-performance amplifier module is based on the Eigentakt technology from PURIFI. Eigentakt is the implementation of PURIFI's continuing research into nonlinear control theory that produced the first mathematically exact largesignal model of self-oscillating amplifier controllers. This breakthrough allows complete optimization of the feedback circuit and improves performance by at least an order of magnitude over existing implementations. The Eigentakt technology allows for extreme low THD at any frequency and power level. The negligible IMD (intermodulation distortion) creates a highly resolved and stable stereo image. Thanks to the very low output noise, this exceptional performance is preserved even at low listening levels.
The 1ET400A also features a comprehensive protection system that makes it robust and easy to integrate.
Features

Negligible Intermodulation Distortion (IMD)
THD remains extremely low at any frequency and any power level
Negligible output noise
High power supply rejection ratio (PSRR)
Controlled, second-order low-pass response
