CYRUS XR SERIES
The wideband power amplifier of the Power-XR 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 Power-XR power amplifier is very capable of reproducing the scale and drama of the musical performance.
POWER-XR
Using our largest toroidal power transformer, a massive 408VA of power is delivered to the high capacity internal power supply.

PSU-XR UPGRADE
The Power-XR includes a port for the PSU-XR power supply. Thirty years ago, Cyrus broke new ground with the introduction of the PSX-R, the first ever regulated power supply upgrade that automatically adapted to match perfectly the power requirements of any connected product. The PSU-XR raises the bar by sourcing no less than five independent regulated supplies in a single box. For the Power-XR, this takes over the power stage to provide a cleaner, more stable supply and deliver higher current to the speakers ensuring better sound and deliverance of sound.
