We are one of the very first companies to get evaluation samples (Serial no 35 and 38) of the latest Class D amp module from new company Purifi Audio. We quickly got to work adapting our Class A REV D buffers to work with the new modules. Initial findings are positive and we will continue to evaluate the sound in the coming months prior to launch.
Production modules are not available till earliest September.
Purifi have given the technology a catchy name of Eigentakt (meaning “self-clocking”)
Purifi, Bruno Putzeys latest development the 1ET400A is a single-channel, ultra-high performance, analog-input Class D Amplifier module capable of over 400W of power at an audio quality level that sets the standard for power amplifiers of any operating class. Its compact size and high reliability makes it fit a broad range of applications, while its audio quality makes it the undisputable choice even in applications where all the premium is on sound quality.
PURIFI’s continuing research into nonlinear control theory has 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 amplifier module further incorporates a comprehensive protection system that makes it tremendously robust and easy to integrate.
We cherry pick state of the art designs from around the world and integrate them into our products. Operating with low overheads and sell direct we are able to combine expensive sonically superior components and sell at aggressive prices.
