Product Summary
The Cyrus 40 PSU is a dedicated external power supply designed to enhance the performance of compatible Cyrus 40 Series components. By taking over key power supply duties from the host unit, it helps deliver cleaner and more stable power, allowing connected products to perform at a higher level.
Power supply design has always been a major part of Cyrus engineering, and the 40 PSU continues that approach with a sophisticated multi-rail architecture and on-board microprocessor control. When connected to a compatible Cyrus component, it automatically configures its output supplies to match the product’s requirements.
Adding a 40 PSU can help improve timing, detail, control and overall musical clarity, making it a valuable upgrade for owners of compatible 40 Series products who want to get even more from their system.
This is an ex-demonstration unit and has been handled with great care. Comes supplied with all original packaging and accessories.
