Gold Note PSU-10 Phono Power Supply for PH-10, Silver

The Gold Note PSU-10 is an external inductive power supply for the PH-10 phono stage that decouples its power from the mains with four transformers and four ultra-low-noise voltage regulators.

It comes in the Series 10 chassis format and therefore looks right next to the PH-10 – this version in silver anodised, brushed aluminium.

Why the PSU-10?

A phono stage amplifies signals in the millivolt range, with MC cartridges even below that. Every bit of hum or mains noise gets amplified along with it. That is exactly where the PSU-10 comes in: three transformers for the supply, a fourth for the dual-choke inductive filter, four separate stages each with its own regulator. Important: for everything to work together, the PH-10 needs the latest firmware – a quick step we are happy to take care of for you.

What you hear

Gold Note promises more dynamics and resolution. With vinyl this mainly means a blacker background between the notes and more space around individual instruments – and the lead-in groove becomes pleasantly unspectacular. The difference is clearest with low-output MC cartridges.

Who is the PSU-10 for?

For anyone running a PH-10 who wants to upgrade it specifically. Bottom line: The PSU-10 is intended exclusively for the PH-10. For the DS-10, HP-10 or CD-10, the PSU-10 EVO is the right power supply – it looks almost the same from outside but is a different unit. Please don’t mix them up; it saves us both an exchange.

Our verdict

The PSU-10 is the logical upgrade for the PH-10 – not a new phono stage, but the better version of the one you already have. Get in touch with HD Zürisee in Wädenswil if you have questions about firmware, placement or combinations; we’re happy to help.

Frequently asked questions

Does the PSU-10 also fit the DS-10 or HP-10?

No. According to Gold Note, the PSU-10 is intended for the PH-10 phono stage. For the DS-10 streaming DAC including the EVO versions, the HP-10 headphone amplifier and the CD-10, there is the PSU-10 EVO. Conversely, the PSU-10 EVO is not compatible with the PH-10 – so the two are not interchangeable.

Does anything need to be changed on the PH-10?

Yes, the PH-10 needs the latest firmware to work with the PSU-10. Gold Note provides the update together with instructions in the download area of its website. If you would rather not do it yourself, our technician will gladly take care of it for you – then everything is ready before the first record spins.
