Description

The Accuphase PS-1250 is a high-end power supply that combines three functions in a single chassis: distribution, filtering, and regeneration of mains power. At the heart of the design is the proprietary Waveform Shaping technology , which compares the input waveform in real time with an ideal reference sine wave and actively corrects any distortion. The result is a reconstructed AC voltage with harmonic distortion equal to or less than 0,08%.

Unlike a simple passive filter, here the signal is cleaned in three distinct stages. The first is a line filter that eliminates high-frequency interference. The second uses a shielded toroidal transformer to reduce common-mode noise. The third reshapes the waveform using a Reference Signal Generator , with a two-stage bandpass filter for out-of-band signals and a six-stage filter dedicated to unwanted harmonics.

The output section is designed like that of a true stereo amplifier: fully balanced circuitry and two power stages with twenty bipolar transistors driven in parallel in a push-pull configuration. This architecture ensures high current peaks and low output impedance, essential for powering demanding power amplifiers without dynamic compression. The voltage regulators accommodate input variations of up to ±10%, maintaining a stable output.

Anyone wondering how to improve the power quality of a hi-fi system will find a concrete answer here: a power conditioner capable of delivering up to 1.200 VA peak (900 VA continuous), with 48.000 µF filter capacitors and passive dissipation, fanless and therefore completely silent. The color LCD display shows waveform, voltage, distortion rate and power consumption in real time, allowing you to monitor the load and avoid overloads. The eight Schuko sockets allow you to connect the entire audio chain—digital sources, DACs , streamers, preamps and power amps—to a single clean and stabilized power source.

About the brand

Accuphase is a Japanese brand specializing in integrated amplifiers, power amplifiers, and CD players that focus on linear frequency response and stable playback over time. They serve those seeking reliable components for mid- and high-end stereo systems, without compromises in construction, and who want to avoid distortion even during prolonged listening sessions.

To choose the right model, evaluate the nominal power in relation to the speakers (the E-470 and AD-60 integrateds cover different needs), the quality of the D/A converter if you use digital sources, and the compatibility with the rest of the chain. Audiocostruzioni carries the entire Accuphase range along with over 70 other brands: you can listen to the components in the Carpi listening room, receive advice on matching and choose between new, guaranteed used and ex-demo based on your budget.
