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

The Gold Note PSX-5.2 is the definitive power supply upgrade for the Series 5.2 range — a purpose-engineered external inductive power supply from Florence that removes the internal power supply's residual influence from the signal path entirely, delivering a darker background, greater dynamic authority, and a more composed and authoritative musical presentation across every component it serves. An evolution of the PSU-5, the PSX-5.2 builds on Gold Note's long-established power supply philosophy with meaningful refinements to its mechanical construction, dual-output architecture, and electrical performance — making it an unrivalled upgrade for those who have already invested in the PH-5.2 phono stage, CD-5.2 CD player, HP-5.2 headphone amplifier, or DS-5.2 streaming DAC, and want to extract the full measure of what those components can achieve.

Black Anodised Aluminium Chassis

The PSX-5.2's enclosure is machined from black anodised aluminium — a deliberate engineering choice that goes beyond aesthetics. Anodised aluminium interacts far less with magnetic fields than conventional chassis materials, reducing a persistent and often underestimated source of interference that raises the noise floor of sensitive audio circuitry. The practical consequence is a quieter, more stable electrical environment for whichever Series 5.2 component is connected — one in which low-level musical detail, previously obscured by the internal power supply's residual noise, becomes fully audible.

4-Rail Audio-Grade Power Supply

The PSX-5.2 is built around four audio-grade power rails, each regulated by ultra-low noise voltage regulators that hold output voltage variation to just 0.05% — a figure that reflects an extraordinary degree of electrical stability under varying load conditions. Line noise rejection exceeds 80dB, as does common mode noise rejection, ensuring that interference from the mains supply is isolated from the connected component with a thoroughness that the internal supply cannot match. Full power response time of under 2.5 microseconds ensures the PSX-5.2 responds instantaneously to the transient demands of the audio signal — maintaining dynamic composure under all musical conditions, from the quietest pianissimo to the most demanding orchestral climax.

Dual-Output Architecture

The PSX-5.2's dual-output design allows both a phono stage and a line-level source to remain permanently connected simultaneously — serving the entire Series 5.2 front end without the need to swap connections or compromise power delivery. When activated, the full energy reserve is directed entirely to whichever component is in use, so there is no dilution of performance between outputs. Dynamic power output exceeds 60W with a standby draw of under 1W — a supply with genuine headroom that operates well within its limits under normal conditions.

Series 5.2 Compatibility

The PSX-5.2 is compatible with the PH-5, PH-5.2, CD-5, CD-5.2, HP-5.2, and DS-5.2 — covering the full breadth of Gold Note's Series 5.2 components. Auto-sensing mains input handles 100–240V at 50/60Hz without adjustment, making the PSX-5.2 equally at home in UK and European systems. Compact dimensions of 200mm × 80mm × 260mm ensure it sits unobtrusively alongside Series 5.2 components on any equipment rack.

Technical Specifications

Who Is It For?

The Gold Note PSX-5.2 is for the Series 5.2 owner who wants to hear what their components are genuinely capable of — without changing any part of the system except the quality of the power feeding it. It is the natural next step after purchasing the Gold Note PH-5.2 phono stage, and an equally worthwhile companion to the Gold Note PA-10 power amplifier for those building a complete Gold Note system. Those exploring the Gold Note turntable range — including the Gold Note Mediterraneo — will find the PSX-5.2 a logical and rewarding addition to a vinyl-first front end.

Buying from Martins Hi-Fi

Martins Hi-Fi has been in Norwich since 1968. Elizabeth Gould runs the business today, and we stock only brands we have heard properly and stand behind.

You can hear the Gold Note PSX-5.2 in our Norwich showroom, demonstrated in the context of a complete Series 5.2 system, so the improvement it brings is immediately apparent rather than a matter of conjecture. When you get in touch, you'll be speaking with Dave, Chris and Tim — experienced specialists who can advise on the PSX-5.2 and your whole system.
