GOLD NOTE PSU-1250

Pre owned. In excellent condition. Free from any noticeable signs of wear. Supplied with owner's manual and original packaging.

The Gold Note PSU-1250 is a super inductive external power supply designed to maximize the performance of the Italian manufacturer’s prestigious Series 1000 components. Developed to partner products such as the CD-1000 MkII, P-1000 MkII, PH-1000, and DS-1000 MkII, it is intended for listeners seeking the highest level of performance from their audio electronics.

Its design focuses on delivering an exceptionally stable and pure power source through the use of carefully selected audiophile-grade components and a highly sophisticated internal architecture. Rated at 1250 watts, the PSU-1250 provides abundant, precisely regulated power, creating the ideal operating conditions for connected components to perform at their full potential.

A key element of the design is the advanced inductive filtering stage dedicated to the analog section, combined with a dual-choke power supply architecture featuring separate inductors for the positive and negative rails. This configuration significantly improves power quality while minimizing electrical contamination that could otherwise affect audio performance.

The PSU-1250 employs a complex seven-transformer architecture. Four transformers are dedicated exclusively to the main power supply stage, including a transformer for galvanic isolation of the audio circuitry, while the remaining three transformers are devoted to the sophisticated Dual Choke inductive filtering system. This design helps isolate sensitive circuits and ensures exceptionally clean, efficient, and stable power delivery.

By accurately filtering the incoming AC supply, the PSU-1250 effectively eliminates unwanted noise and interference, reducing both EMI (Electromagnetic Interference) and RFI (Radio Frequency Interference) that can compromise signal integrity. The ultra-clean power delivered to connected electronics allows the entire system to achieve noticeably higher levels of performance.

The sonic benefits include improved dynamics, greater resolution, enhanced retrieval of fine musical details, and superior control over the soundstage. The result is a more natural, realistic, and engaging listening experience, capable of revealing the most subtle nuances of a recording while elevating the overall performance of Gold Note Series 1000 components.
