With support for high-resolution formats up to 32-bit/768kHz PCM and DSD1024, the digital stage is engineered for maximum resolution and clarity. Every element of the DAC layout has been tuned in-house by the Cyrus team to achieve a signal path of extraordinary precision. Digital inputs include asynchronous USB-B, coaxial, optical, and HDMI eARC, allowing full integration with streamers, TVs, and other sources.

MM Phono Stage

Cyrus has included a low-noise moving magnet phono input that borrows design principles from the award-winning Classic Phono. With a wide dynamic range and low background noise, the phono stage provides a clean, articulate signal path for any quality turntable, bringing analog warmth and musicality into the same chassis as your high-res digital sources.

Power Amplifier

With 100 watts per channel into 6 ohms, the 40 Amp delivers punch and control across the full frequency range. The wideband amplifier design offers a frequency response that extends from DC to beyond 100kHz, ensuring phase integrity and resolution across all content. Its generous, over-specified power supply allows the amplifier to reveal scale and subtlety without strain, even during dynamic peaks.

PSU Upgrade Option

For those looking to extract every ounce of sonic performance, the 40 Amp can be connected to the Cyrus 40 PSU external power supply. The 40 PSU provides multiple digitally controlled low-noise voltage rails, isolating the DAC and preamp sections for even greater purity and stability. A single connection cable makes integration seamless, and the audible gains in noise floor and headroom are immediately apparent.
