Product Summary
The Cyrus 80 PWR is a high-performance Class A/B power amplifier designed to provide the authority, control and dynamic headroom required by a premium separates hi-fi system. Created as the ideal power-amplifier partner for the Cyrus 80 PRE, it can also be used with another compatible preamplifier, network streamer or source component fitted with a volume-controlled analogue output.
In its standard stereo configuration, the 80 PWR delivers 200 watts of amplification for a powerful and controlled two-channel listening experience. This gives the amplifier the scale and drive required to work with a wide range of standmount and floorstanding loudspeakers, including designs that benefit from substantial amplifier power and firm driver control.
For systems requiring even greater power and separation, the amplifier can be switched into bridged mono operation. In this configuration, a single 80 PWR delivers 300 watts to one loudspeaker, allowing two amplifiers to be used as dedicated left- and right-channel monoblocks. This provides increased headroom, channel separation and system-upgrade flexibility.
Balanced XLR and unbalanced RCA inputs allow the 80 PWR to connect to a variety of compatible preamplifiers. The full-width 80 Series chassis provides additional internal space for the amplifier and power-supply circuitry, while the understated black finish and clean front-panel design allow it to integrate neatly with the Cyrus 80 PRE and other premium hi-fi components.
