Gold Note PSU-1250 – Super Inductive External Power Supply for 1000 Series

Unlock more dynamics, lower noise and greater realism from your Gold Note 1000 Series electronics. The Gold Note PSU-1250 is a super inductive external power supply engineered to deliver ultra-clean, high-current power while reducing interference and electrical noise. Designed as the ideal companion for components such as the CD-1000 MkII, DS-1000, PH-1000 and P-1000 MkII, it elevates resolution, control and musical flow across your entire system.

• 7-transformer architecture with galvanic isolation and Dual Choke inductive filtering
• Ultra-clean power delivery for greater dynamics, finer detail and improved realism
• Selectable absolute phase control (0° / 180°) from the front panel
• Premium brushed aluminium finishes: Black, Silver or Gold

Product Overview

The Gold Note PSU-1250 is a dedicated external power supply developed for the Gold Note 1000 Series. Its purpose is simple: remove the limitations of standard internal power supplies by delivering a more stable, cleaner and higher-current energy source—without introducing EMI (electromagnetic interference) or RFI (radio-frequency interference) that can compromise low-level audio signals.

At its core is a sophisticated design built around a double inductor driving both the negative and positive high-current stages, paired with an inductive filter on the analogue stage. This architecture is designed to filter the AC current, suppress disturbances and keep the connected component operating in optimal conditions, even when the mains is less than perfect.

Listening Experience

When added to a compatible Gold Note 1000 Series component, the PSU-1250 typically brings a more effortless, more controlled and more resolved presentation. You can expect tighter bass definition and stronger impact, improved separation between instruments, and a quieter background that makes fine textures and ambience easier to perceive.

Dynamics tend to feel less constrained—transients are cleaner, complex passages stay composed, and the soundstage gains stability and depth. In short: the system sounds more confident and more “free”, with improved realism and musicality.

Use Cases

• Reference digital playback: enhance a Gold Note CD-1000 MkII or DS-1000 with cleaner power and greater low-level resolution.
• Vinyl performance boost: give the PH-1000 a lower-noise foundation for better micro-detail, headroom and spatial clarity.
• Preamplifier refinement: improve control and realism with the P-1000 MkII by reducing interference and stabilising power delivery.
• System-wide uplift: maximize the performance potential of a full Gold Note 1000 Series stack.

Installation & Placement Tips

For best performance, place the PSU-1250 at a reasonable distance from other audio electronics. It should not be placed directly above or below the unit it powers, and should not be positioned too close to other electronics. Proper placement helps minimise any potential interaction and keeps your system performing at its best.
