Cyrus Classic POWER Power Amplifier Overview The Cyrus Classic POWER amplifier delivers exceptional performance, offering 144W per channel into 4Ω, 110W into 6Ω, and 87W into 8Ω. Designed to complement the Classic PRE, it brings a significant upgrade in audio fidelity. Drawing from the advancements of the XR Series, this amplifier ensures a dynamic and detailed listening experience. Its compact design houses a robust 408VA toroidal transformer, providing ample power reserves for demanding speakers. Ideal for audiophiles seeking clarity and precision in their sound system. Design Encased in a sleek die-cast chassis, the Classic POWER amplifier measures 75mm in height, 215mm in width, and 355mm in depth. Weighing 7.3kg, it combines durability with a minimalist aesthetic. The front panel features a clean, understated design, while the rear panel offers multiple connectivity options, including RCA and XLR inputs, a 12V trigger, and an MC-BUS connection for system integration. Its compact footprint allows for flexible placement in various audio setups. Performance With a frequency response extending from below 0.5Hz to over 48kHz, the Classic POWER ensures accurate reproduction of audio signals. The amplifier maintains a total harmonic distortion plus noise (THD N) of less than 0.002% at 1kHz and 2/3 power into 6Ω, delivering clean and precise sound. The high signal-to-noise ratio exceeding 100dB further enhances the listening experience by minimising unwanted noise and preserving the integrity of the audio signal. Connectivity The Classic POWER amplifier is equipped with both unbalanced RCA and balanced XLR inputs, offering versatility in connecting to various audio sources. The 12V trigger input allows for seamless integration with other components, enabling automatic power-on functionality. Additionally, the MC-BUS connection facilitates control integration within a Cyrus system, providing a unified and streamlined user experience. These connectivity options ensure compatibility with a wide range of audio equipment. Upgrade Potential For audiophiles seeking enhanced performance, the Classic POWER features a port for the PSX-R2 power supply. Connecting the PSX-R2 directs power to the voltage amplifier stage, offering a more stable and low-noise power supply. This upgrade can further refine the amplifier's performance, delivering an even more detailed and immersive listening experience. The PSX-R2 power supply is available separately, allowing users to tailor their system to their specific audio preferences.
