Accuphase PS-1250 Power Supply

Accuphase PS-1250 Clean Power Supply

Pure, stable, and ultra-low distortion AC power for high-end audio performance.

The Accuphase PS-1250 Clean Power Supply is a precision-engineered power conditioner designed to deliver the cleanest, most stable AC power possible to your audio system. By actively reshaping incoming power and reducing total harmonic distortion to 0.08% or less, the Accuphase PS-1250 enhances clarity, dynamics, and tonal balance across your entire setup.

This reference-grade unit uses a large toroidal transformer, high-capacity filtering, and a fully balanced power amplifier circuit to generate an ideal sine wave output. The result is pure, distortion-free AC power that reveals every nuance in your recordings while protecting your equipment from voltage fluctuations and noise.

The Accuphase PS-1250 includes a detailed front display showing input/output voltage, waveform, total distortion, and load status, allowing users to monitor power quality in real time. Its massive chassis, internal shielding, and quiet analog operation ensure absolute stability with no digital switching noise.

Perfect for powering amplifiers, preamplifiers, DACs, and turntables, the Accuphase PS-1250 provides both sonic and operational improvements in any serious audio system. Every component connected to it benefits from deeper bass, improved soundstage definition, and an impressively black background.
