Cyrus Electronics

Cyrus - PSX-R₂ - Regulated External Power Supply

The PSX-R₂ is an external power supply, which is designed to work with certain of our core hi-fi separates range – namely those products where the circuits have been designed in such a way to benefit from this addition and provide a fantastic upgrade path.

The PSX-R₂ provides an extremely smooth and stable DC feed allowing any partnered component to achieve its full potential. In terms of performance, you will perceive new levels of fine detail with the PSX-R₂, allowing you to appreciate the subtle emotional nuances that truly expose the performer’s emotion and passion.

A revolution in power supply design

The concept is that a power supply provides a super smooth DC feed to the highly refined electronics so you can hear the full potential of the products you have purchased.

In many products, the PSX-R₂ works in tandem with the built-in power supply to allow each part of the unit to be powered separately. It thereby removes any cross-contamination from for example the motors in a Cyrus CD player or our famous Phono Signature

This Audiophile power supply works by providing a regulated DC power feed free of negative artifacts that are present in all domestic mains supplies. Connecting a PSX-R₂ external power supply enables the high-grade components in the partnering component to perform to their full potential. This is one of our most popular upgrades and is highly recommended. The PSX-R₂ provides new depth and detail to the sound output of partnering products by providing extremely low noise power to the circuits within the unit. Low noise high gain amplifiers connected in a propriety design filter out any unwanted noise and provide remarkable benefits in sound quality. If you consider that amplifiers and other audio electronics work by making copies of the incoming signal, it is obvious that the copy will sound better because if DC voltage lines are cleaner. A stable, strong and separated power supply can provide huge sound quality benefits for a hi-fi system.
