Bought new (demo ex) in 2005. Great condition.

Description (from Cyrus homepage)

The SmartPower is a most versatile and fully-featured power amplifier. The SmartPower is an excellent upgrade for a Cyrus integrated amplifier, voiced to closely match the Cyrus 8, either to upgrade the performance of the internal power amplifier, or to use both the internal power amp and the SmartPower in a bi-amped configuration. The fixed gain structure of the Cyrus range enables any Cyrus power amplifier, such as the SmartPower, to be matched for bi-amping to any Cyrus integrated amplifier with a pre-out connection.

The SmartPower features a sophisticated music-sense circuit with microprocessor control. When the unit is set to low-consumption Standby a high-sensitivity circuit will detect an incoming music signal and switch on the amplifier noiselessly ready for use. A precision timer in the control system will then hold the amplifier on for 4 minutes before resetting to a semi-Standby state. From this state the amplifier can be wakened instantly so that even subtle low-level background music or effects signals will not be lost as the amplifier exits standby. If music is not present for an extended period then the SmartPower will revert back to its true low-consumption standby state.
