Cyrus 40 PSU External Power Supply - Black

Cyrus 40 PSU External Power Supply – Black

Unlock the full potential of your Cyrus 40 Series components with the Cyrus 40 PSU External Power Supply. Engineered with precision and finished in sleek brushed aluminium, this external unit provides ultra-clean, stable and intelligent power to enhance sound quality, clarity, and overall musical performance.

Precision Power, Perfectly Controlled

The Cyrus 40 PSU is much more than a standard power supply. Built with an onboard microprocessor, it communicates directly with your connected host device—be it the 40 AMP, 40 CD, 40 ST, or future 40 Series models—to deliver precisely regulated voltage levels for each section of the circuit. This digital control ensures that every component receives the exact power it needs, minimising distortion, jitter, and electrical noise.

Revolutionary Power Supply Design

Power delivery is fundamental to audio performance, and Cyrus has completely redefined this with the 40 PSU. Housed in the signature 40 Series aluminium chassis, it incorporates five independent power supplies—each designed for specific circuit types:

• One high-capacity logic supply for powering digital circuitry.
• Two fixed-voltage supplies for low-voltage analogue circuits.
• Two variable high-capacity supplies that feed both high- and low-consumption analogue circuitry such as amplifiers and DACs.

The variable supplies can also switch between regulated and unregulated voltage modes (+10V–+45V DC regulated, or +45V/+56V DC unregulated), providing maximum flexibility and clean headroom for power-hungry components.

Optimised Power for Every 40 Series Component

Each 40 Series product benefits from the 40 PSU’s advanced power management in unique ways:

40 AMP – Enhanced Authority and Precision

When paired with the Cyrus 40 AMP, the 40 PSU delivers extra reserves of clean power to the amplifier’s main rails, strengthening signal tracking and improving accuracy.

• The pre-amplifier stage is fully powered by the 40 PSU, providing greater stability and lower distortion.
• The DAC section inside the amplifier receives less load, resulting in cleaner conversion and richer, more open sound.
  Listeners will notice greater transparency, improved detail retrieval, tighter bass, and an effortless dynamic flow.

40 CD – Smoother Timing, Cleaner Playback

For the Cyrus 40 CD player, the 40 PSU powers the master clock and motor drive system.

• By offloading these noisy electrical circuits to an external source, internal interference is dramatically reduced.
• It also drives the analogue side of the DAC, while the internal supply handles the digital section, separating power paths for better clarity and focus.
  Expect improved timing, lower jitter, deeper bass control, and cleaner note edges with enhanced imaging.

40 ST – Expanded Soundstage and Resolution

Connected to the Cyrus 40 ST streamer, the 40 PSU powers both the analogue DAC stage and BluOS network module. This ensures an ultra-stable current flow to sensitive audio circuits, minimising background noise and boosting signal integrity.
You’ll experience wider sound staging, greater separation between instruments, and a more three-dimensional listening experience.

Engineered to Perform, Designed to Impress

Maintaining Cyrus’s iconic half-width form factor, the 40 PSU’s anodised aluminium chassis is both compact and robust. It not only complements the 40 Series aesthetic but also aids in heat dissipation and mechanical isolation—further contributing to performance stability.

This understated yet elegant design allows the PSU to sit neatly alongside other 40 Series components, creating a cohesive and professional system stack.
