PRD-3S High End  Preamplifier/DAC
 
The PRD-3S is an essential part of Gato Audios reference system, the perfect partner for the PWR-222 mono block power amplifiers.
 
"S" is for Super
 
– the PRD-3S is anything else than the subtle makeover of the standard PRD-3. It is a highly improved and extremely high performing preamplifier designed and optimized to work with our brand new PWR-222 mono blocks. It now even features an aptX Bluetooth receiver circuit that enables streaming from computer, phone or tablet in high quality.
 
We changed and improved the electrical circuits and layouts in more than twenty ways, the most significant being:
 
Optimized mains filter
Improved general and local power supplies
New input stage
Improved line stage
New analogue stages in the D/A converter
Improved digital signal routing
Updated firmware
Improved connectors
Incorporated aptX Bluetooth module
 
Don't miss the opportunity to give this preamplifier a listen – we are certain that it will impress with clean, smooth and detailed pre-amplification that does not only offer built-in D/A converter and aptX Bluetooth – but also the ability to bring out the best in your setup.
 
Smooth analogue music
 
The analogue input stage is where everything begins. It not only connects external inputs and the built-in D/A converter with the output stage, it adapts impedances, adjusts levels and switches signals. A super-gentle embrace of the delicate analogue signals is important for the total performance of the preamplifier. At Gato Audio we have utilized our many years of experience in "voicing" analogue amplifiers to make this particular stage perform at its very best. We tuned the input stage to perform with a natural and lifelike sound, affecting the original signal as little as possible.
 
More than just a Preamp
 
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.
 
Versatility and Connectivity
We had our eye on versatility and connectivity when designing this preamplifier. The PRD-3S offers not only a wide range of digital and analogue inputs, but also line outputs, a trigger signal for external power amplifiers, and a configurable home theater input. The HT input can turn the preamplifier into a fixed level preamplifier for use in a surround setup, without compromising the sonic performance.
