State of the art class-D amplifier by SoundImpress

Thanks to high precision parts such as op-amps, high voltage gate drivers and high current MOSFETs, this amplifier can power almost any speaker. Be it a single subwoofer or your sophisticated 3-way tower. Thanks to the efficiency a high loop gain can be obtained, creating an unparalleled performance.

The Eigentakt implementation from Purifi is one the best amplifier technologies available. This class-D technology meets high standards and gives super performance at any playback level, regardless of load. This results in a stable, dynamic and realistic sound image, at any music genre. This amplifier will squeeze (with a proper music source and proper pre-amplification) all the dynamics out of your music without distortion, and at any volume.

Minimalistic but powerfull

Packed within a minimalastic high quality aluminum chassis, this is more than just another powerful amplifier. Gone are the days of needing to have a massive heavy weighted mono power amplifier to have excellent sound and achieve some volume. The amplifier can deliver all its power from as low as 2 ohm impedance combined with low idle loss, very low distortion and noise levels!

In addition, this amplifier has a nice appearance, an imposing look that takes away all the attention from your other home audio devices. A minimalistic design without compromising on performance or additions of cooling elements. Every amplifier comes with our own stamp of approval, our iconic “S”-logo, on the front plate. This branding ensures that you own a piece of real quality, that is built to last. A small (dimmable) LED displays is implemented to show when the device is on or off.

But not only the case is puristic; the mono amplifier features the input and outputs your speaker set-up deserves. The amplifier features XLR balanced inputs. Convenient banana-plug speaker connectors have been chosen as outputs.

This 400 watt mono class-D amplifier is ready to bring new life to any system!
