Digital Performance
Customised DAC design is at the forefront of all digital products from Cyrus, and the 40 AMP embodies this approach like never before. Based upon the ESS Sabre ES9039Q2M chipset and HyperStream IV Dual DAC technology, the 40 AMP supports up to 32-bit 768kHz PCM & DSD1024 audio files. Every component has been analysed by our engineering team and the board layout fully optimised to tune the DAC so that we can achieve the highest possible performance.
MM Phonostage
As well as multiple digital and analogue connections, the 40 AMP has a low noise MM phono stage which inherits many of its design features from the award-winning Classic PHONO. This phono stage performs at a level way above its class, featuring low background noise and high dynamic range, providing the perfect complement for any quality vinyl turntable source.
Power Amplifier
The wideband power amplifier of the 40 AMP responds from D.C. to beyond 100kHz ensuring ruler flat frequency response and keeping any undesirable phase shifts out of the audio band. With a generous, over-specified power supply the 40 AMP power amplifier is very capable of reproducing the scale and drama of the musical performance.
PSU
Even when the 40 AMP is packaged with our latest custom designed switch mode power supply, improvements are always possible. To further enhance the experience and provide the 40 AMP with the best configuration of power, you can easily connect the 40 PSU external power supply to the 40 AMP with a single cable. Providing multiple supplies, all of the output voltages from the 40 PSU are digitally controlled internally, so are extremely stable and virtually noise free.
