Description
The Gold Note PSU-1250 Power Supply Upgrade is the ultimate external power solution designed specifically for the prestigious 1000 Series components, including the CD-1000 MkII, P-1000 MkII and PH-1000. Engineered to elevate performance to reference level, the PSU-1250 delivers ultra-clean, highly stable energy that allows connected electronics to perform at their absolute best.
By relocating and dramatically enhancing the power stage in a dedicated chassis, it reduces interference, improves signal integrity and unlocks greater musical realism. Designed as the flagship model in the range, the PSU-1250 represents the most advanced expression of Gold Note’s super inductive power technology, offering a substantial upgrade for discerning audiophiles seeking uncompromising performance.
Seven-Transformer Super Inductive Architecture
At the core of the PSU-1250 lies an exceptionally sophisticated seven-transformer configuration. Four transformers are dedicated exclusively to the power stage, ensuring abundant current delivery and unwavering stability under dynamic demand. A separate transformer provides galvanic isolation for the audio stage, while three additional transformers are devoted to the Dual Choke inductive filter.
This advanced double-inductor topology independently manages the positive and negative rails, dramatically reducing ripple and unwanted noise. With seven low-noise voltage regulators and a maximum output voltage variation of just 0.05%, the PSU-1250 guarantees an extraordinarily precise and consistent power supply, forming a rock-solid foundation for high-end audio reproduction.
Ultra-Clean Energy, Maximum Musical Expression
The PSU-1250 is designed to eliminate line noise and common mode interference exceeding 80dB, preventing electrical disturbances from contaminating sensitive analogue circuits. Its rapid full power response time of less than 2.5 microseconds ensures immediate current availability during demanding musical passages.
Delivering over 300W of dynamic power while consuming 100W, it provides generous reserves without generating electromagnetic or radio-frequency interference. The audible impact is unmistakable: deeper bass authority, improved midrange transparency and enhanced high-frequency refinement.
Soundstage depth expands, instrument separation becomes more precise and micro-details emerge from a quieter background, resulting in a more lifelike and emotionally engaging listening experience.
Why It Surpasses the PSU-1000
While the PSU-1000 already offers significant performance gains, the PSU-1250 stands clearly above it in both architecture and output capability. The PSU-1000 features a five-transformer configuration and five voltage regulators, whereas the PSU-1250 expands this to seven transformers and seven regulators, providing superior isolation and greater current capacity.
With over 300W of dynamic power compared to the PSU-1000’s 200W, the PSU-1250 delivers enhanced headroom and control, particularly in complex or high-demand systems. This expanded design translates into improved authority, lower noise floor and greater overall stability, making it the preferred choice for those seeking the highest level of refinement from their 1000 Series electronics.
Intelligent Control and Seamless Integration
Beyond its advanced engineering, the PSU-1250 incorporates practical features to ensure perfect system integration. Absolute phase control can be selected directly from the front panel, allowing precise optimisation within complex audio setups. Standby power consumption is limited to just 1W, maintaining energy efficiency without sacrificing readiness.
The dedicated one-metre PSU connection cable ensures secure and optimised power transfer between units. Every detail has been carefully considered to maintain signal purity and operational reliability, ensuring the PSU-1250 works harmoniously with your system while delivering consistent, high-performance results.
Premium Construction and Authoritative Presence
Housed in a substantial 430mm-wide aluminium chassis measuring 135mm in height and 360mm in depth, the PSU-1250 matches the aesthetic and build quality of the 1000 Series. Weighing 21kg net, its robust construction reflects the serious engineering contained within.
Operating on 100-120V or 220–240V with automatic voltage sensing, it is globally compatible and built for long-term reliability. The Gold Note PSU-1250 Power Supply Upgrade is the definitive enhancement for owners of 1000 Series components, delivering greater dynamics, superior resolution and uncompromised musical realism at the highest level.
