Gato Audio DIA-400S

The reference in Class-D amplification with our all new Roon Ready streaming module built-in is an absolute killer among the one box solutions in the market today.

The DIA-400S amplifier offers a state of the art Class-D output stage with dedicated and optimized switch mode power supplies. The multiple stage power amplifier is built around proven technology from International Rectifier, optimized with a precision high frequency oscillator and PWM modulator. A pair of precision switching MOS-FET transistors, with super low on-resistance ensures the high frequency switching is done perfectly and with as little loss as possible. The output filters are made from quality PP capacitors and low DCR coils, converting the high power PWM signals back into detailed and smooth analogue music.

The built-in D/A converter offers real high end performance, enabled by the use of a dedicated power supply, a balanced-drive Burr-Brown PCM1794 D/A converter, an optimized high bandwidth I/V converter, and an analogue stage with low-Q, low pass filters. All digital inputs are upsampled to 24bit/192kHz. This D/A converter will upgrade any digital source - such as wired or wireless streaming from your computer or CD drive - to a high end level of detail and musical performance.

NPM - Network Player Module
The built in NPM is a powerfull way of transforming the DIA-400S into a high end network streamer. It connects to the network by Ethernet cable or Wi-Fi, and is controlled by a smartphone or tablet app or as a Roon endpoint. The following services are supported:

Roon Ready
Tidal
Qobuz
Deezer
DLNA UpNP

The Bluetooth input of the NPM supports aptX HD 24Bit audio. This means that your DIA-400S is able to receive audio from every smartphone or tablet app in a "better-than-CD" quality.
