Cyrus Power-XR and Classic POWER: Compact power amplifiers from Britain

The British company Cyrus Audio has released new stereo power amplifiers in the XR and Classic lines. The new products are named Cyrus Power – XR and Cyrus Classic POWER , respectively. These are transistor amplifiers made in a proprietary compact form factor. However, the amplifier output stages operate in class A/B.

According to the manufacturer, the new Cyrus Power-XR and Classic POWER have lower noise levels than previously produced models. At the same time, the output stages are capable of delivering high current to the load, which allows them to successfully cope with acoustic models that are difficult for amplifiers.

Cyrus Power-XR Stereo Power Amplifier

The Cyrus Power-XR wideband power amplifier delivers 110 watts when driven into a 6-ohm load in each of its two channels. At the same time, the operating range of the new product extends almost from constant voltage to a frequency exceeding 100 kHz. The amplifier is equipped with both unbalanced and balanced inputs, a 12 V trigger input, a proprietary MC-BUS control bus and a connector for connecting an optional external power supply Cyrus PSU-XR. There is also a USB port for updating the firmware.
