Gold Note PSU-10 Evo
The Gold Note PSU-10 Evo is an external power supply unit designed exclusively for the Gold Note PH-10 phono stage — and it represents one of the most significant single upgrades available to any PH-10 owner. Where the standard internal power supply delivers excellent results, the PSU-10 Evo eliminates the compromises inherent in sharing a chassis with sensitive analogue circuitry, providing the PH-10 with a vast, ultra-clean power reserve drawn from a dedicated, purpose-built unit.
Dual Choke Hybrid Inductive Filter Design
The PSU-10 Evo is built around Gold Note's proprietary Dual Choke Hybrid inductive filter — a design that goes far beyond conventional regulation. A double inductor drives both the negative and positive high-current stages simultaneously, creating an inductive filter on the analogue stage that suppresses interference and electrical noise from the AC mains with extraordinary thoroughness. Line noise rejection and common mode noise rejection both exceed 80 dB — figures that translate directly into a lower noise floor, greater dynamic contrast, and finer low-level detail in the music.
Four-Rail Audio Grade Power Supply
Four separate transformer rails, each regulated by ultra-low-noise voltage regulators, feed the PH-10 with complete independence between circuit functions. Maximum output voltage variation is held to just 0.05% — a measure of the stability that underpins the PSU-10 Evo's ability to transform the PH-10's performance. Full power response time of less than 2.5 µsec ensures the supply reacts instantaneously to the demands of complex musical passages, delivering effortless dynamic realism where a lesser supply would compress and smear transients.
Complete Isolation from the AC Grid
By moving the power supply entirely outside the PH-10's chassis, the PSU-10 Evo achieves a level of isolation from the AC power grid that no internal supply can match. The result is an ideal working environment for the PH-10's analogue circuitry — one in which the electronics can operate entirely free from the interference and contamination that compromise lesser phono stages. The improvement in resolution, imaging, and musical authority is not subtle.

Who Is It For?
The PSU-10 Evo is for the PH-10 owner who wants to hear everything the phono stage is genuinely capable of. It is a natural, unhesitating recommendation for anyone running the Gold Note PH-10 with a high-performance cartridge — whether that is the Gold Note Donatello, the Gold Note Machiavelli MkII, or the flagship Gold Note Tuscany. If you are investing seriously in analogue replay, the PSU-10 Evo is not optional — it is the completion of the PH-10's design.
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. We can demonstrate the PSU-10 Evo paired with the PH-10 in our Norwich showroom, so you can hear precisely what a dedicated external power supply contributes to the analogue signal path. When you get in touch, you'll be speaking with Dave, Chris and Tim — experienced specialists who can advise on this product and your whole system.
