Gold Note PSX-5.2 | External Power Supply for the Gold Note 5.2 Series

A focused, purposeful upgrade for the Gold Note 5.2 series — delivering greater background silence, improved dynamic authority and support for two components simultaneously.

The Gold Note PSX-5.2 is a dedicated external power supply designed specifically for Gold Note's 5.2 series components. An evolution of the PSU-5, it builds on the same core principles of low noise and musical authority that have defined Gold Note's power supply philosophy, while introducing meaningful refinements to its mechanical construction, power delivery and versatility of use. For those who already own — or are considering — a Gold Note PH-5 phono stage or a compatible 5.2 series source component, the PSX-5.2 represents a logical and worthwhile step forward.

Key Features

• Dedicated 5.2 series compatibility — designed specifically for use with the PH-5, PH-5.2, CD-5, CD-5.2, HP-5.2 and DS-5.2, ensuring optimally matched power delivery for each supported component.
• Dual-output architecture allows both a phono stage and a line-level source to remain permanently connected, so the PSX-5.2 serves the entire front end without the need to swap connections.
• Black anodised aluminium chassis — a deliberate engineering choice that reduces interaction with magnetic fields, contributing directly to a lower noise floor and greater retrieval of low-level detail.
• 4-rail, audio-grade power supply with two ultra-low noise voltage regulators, delivering maximum output voltage variation of just 0.05% and line noise rejection exceeding 80dB.
• Full power response time of under 2.5 microseconds ensures the PSX-5.2 responds instantaneously to transient demands in the audio signal, maintaining dynamic composure under all operating conditions.
• Dynamic power output exceeding 60W with a standby draw of under 1W — a supply with genuine headroom that operates well within its limits under normal use.
• Compact dimensions at 200mm × 80mm × 260mm make the PSX-5.2 easy to accommodate alongside 5.2 series components without dominating the equipment rack.

Technology & Design

The PSX-5.2 takes a structurally refined approach to external power supply design. Its black anodised aluminium enclosure is not simply an aesthetic choice; the material and finish are selected to minimise magnetic field interaction, which in practice means a quieter, more stable electrical environment for the connected component. The power supply itself uses four audio-grade rails with ultra-low noise voltage regulators and achieves common mode noise rejection in excess of 80dB — figures that translate directly into a darker background against which fine musical detail becomes more readily audible. The dual-output architecture is a practical innovation: both outputs remain permanently connected, but when activated, the full energy reserve is directed entirely to whichever component is in use, so there is no dilution of power delivery. The unit is compatible with 100–240V mains supplies with auto-sensing, making it equally at home in UK and European systems.

Listening Experience

The improvements the PSX-5.2 brings to a Gold Note 5.2 system are of the kind that become more apparent with time rather than immediately obvious in isolation. The background becomes quieter in a way that allows the texture and body of instruments to emerge more fully — string tone gains more natural decay, piano notes resolve with better separation between attack and sustain, and bass lines become easier to follow with greater pitch definition. Paired with the Gold Note PH-5 phono stage, the effect on vinyl playback is a more composed and settled presentation, with dynamic peaks delivered with less apparent effort. It is the kind of upgrade that improves the listening experience across all material rather than flattering particular recordings.

Technical Specifications

The Gold Note PSX-5.2 is available to discuss and demonstrate at our Norwich showroom, where we can show it in the context of a complete Gold Note 5.2 system. If you would prefer to evaluate the upgrade at home, our home evaluation service is available across Norfolk and East Anglia. To arrange either, please call 01603 627010 or email info@martinshifi.co.uk.
