Description 40 PSU Power supply design has always been key to the overall performance of audio products. Incorporating its own on-board micro-processor, the Cyrus 40 PSU communicates directly with the host product. This consistently provides the best configuration of virtually noise-free power from the full range of digitally-controlled voltage output levels. 40 AMP Enhancements When connected to the Cyrus 40 AMP, the 40 PSU provides the power amplifier section with a serious boost of clean power. This further stiffens the main power supply rails to the amplifier, meaning that the amplified signal can more accurately track the input signal. You hear a new accuracy in the music, which becomes more transparent and more detailed. The Pre-Amp section is completely driven by the 40 PSU, again this means a stiffer supply, leading to greater accuracy. 40 CD Enhancements When connected to the Cyrus 40 CD, the 40 PSU powers the master clock, which helps to improve jitter. It also powers the CD motors, which is – electrically speaking – a very noisy circuit as the motors are constantly changing velocity. Taking this supply outside the box lowers the overall noise within the box, helping the player to perform even more accurately. 40 PSU also takes over powering the analogue side of the DAC, with the internal supply powering the digital side. 40 ST Enhancements When connected to the Cyrus 40 ST, the 40 PSU takes over powering the analogue side of the DAC and the BluOS network module. This provides those sections with a cleaner, more stable supply of power. This improves audio performance, and brings out new levels of detail in the music, as well as offering greater control. The use of 40 PSU also creates more space round the instruments and vocals, providing greater depth and a holographic soundstage.
