Our Review

Gold Note PSU-1250 Power Supply Review

I. Introduction

In the quest for audiophile-grade sound, every component in the signal chain plays a crucial role, with the power supply being a fundamental piece of the puzzle. Clean and stable power is the bedrock upon which high-fidelity audio systems are built, and the Gold Note PSU-1250 Power Supply has been designed with this philosophy in mind. It promises to deliver an uncompromised electricity supply to your electronics, ensuring that they perform to their utmost potential.

II. Design and Build Quality

The Gold Note PSU-1250 boasts a robust 7-transformer design that is as ambitious as it is effective. Each transformer is purposed to cater to specific requirements within the power supply, ensuring that energy delivery is both precise and isolated from unwanted electrical noise. This level of detail extends to the construction materials and available finishes, including Black, Silver, and Gold anodized aluminum, which exude a sense of premium quality.

However, with a net weight of 21Kg and a boxed weight of 27Kg, potential buyers must consider the practicalities of housing such a substantial unit. Not every equipment rack or shelf is designed to accommodate such heft, and the PSU-1250 demands a sturdy, dedicated space within your audio setup.

III. Technical Specifications and Features

Diving into the technicalities, the PSU-1250's transformers include four for the power supply stage, one for audio stage galvanic insulation, and three dedicated to the dual choke inductive filter. This separation of duties is key to its performance, minimizing interference between stages.

The device’s remarkable EMI/RFI rejection capabilities (>80dB) are a testament to its design, ensuring that electromagnetic and radio-frequency interference do not tarnish the audio signal. The PSU-1250's maximum output voltage variation is impressively low at 0.05%, a figure that speaks to the stability of the power it provides.

Furthermore, features such as Absolute Phase Control, which can be adjusted from the front panel, and an extremely fast Full Power Response Time of less than 2.5µsec, showcase Gold Note's commitment to delivering power that is not only clean but also responsive to the dynamic demands of audio playback.

IV. Performance

The true test of any power supply unit is its effect on the sound quality. The PSU-1250 is designed to enhance the performance of your electronics by providing ultra-clean power, which should translate to greater dynamics, better resolution, precise details, and a sense of maximum realism in audio reproduction.

Its dynamic power capacity of over 300W means it can comfortably handle power-hungry equipment, while a power absorption of 100W and standby power of less than 1W indicate a device that is both powerful and efficient.

V. User Experience

From a user perspective, the Gold Note PSU-1250 aims to be as user-friendly as it is high-performing. The front panel offers accessibility and ease of control with its Absolute Phase Control feature. Its automatic voltage selection (100-120V / 220-240V; 50/60Hz) simplifies setup, and the sub-1W standby power consumption is a welcome feature for the energy-conscious user.

VI. Comparison with Competitors

When positioned against its competitors, the PSU-1250 holds its ground with distinctive features like its multi-transformer design and exceptional noise rejection capabilities. While its price point may place it in the higher echelons of the market, for the discerning audiophile, the investment could well be justified by the audible improvement in their audio system's performance.

VII. Pros and Cons Recap

The Gold Note PSU-1250 Power Supply is a formidable contender in the realm of high-end audio power supplies. Its strengths lie in its ability to deliver ultra-clean power, enhancing the sonic performance of connected electronics and effectively eliminating EMI and RFI interference. The dedicated transformers and advanced noise rejection technology are standout features.

On the downside, its considerable weight might pose a challenge for some setups, and the limited availability of the black finish could be a minor inconvenience for those with specific aesthetic preferences. Additionally, while the PSU-1250's benefits are clear, some users may seek more explicit details regarding the specific performance improvements they can expect.

VIII. Final Thoughts

For the audiophile who values pristine power delivery, the Gold Note PSU-1250 is a compelling choice. It is engineered to elevate the performance of high-fidelity audio systems, and its meticulous design is a testament to Gold Note's commitment to audio excellence.
