What customers say
The NuPrime Pure AC-4 garners overwhelmingly positive sentiment, primarily for its ability to dramatically lower the system noise floor. Users consistently report 'blacker backgrounds,' which significantly enhances clarity, micro-dynamics, and transient precision. Beyond cleaning power, the unit is praised for its robust, high-quality construction and effective isolation between its four outlets, preventing digital contamination of analog stages. While positioned in the premium category, dedicated users view the sonic improvements as a substantial and worthwhile investment, often yielding greater perceived upgrades than swapping other components. The AC-4 is established as a performance enhancer that unlocks the full potential of high-fidelity gear.
Know before you buy
The AC-4 uses a 7th-order LC filter for sensitive, low-power components like DACs and preamps to eliminate noise, while a 5th-order LC filter is dedicated to high-power amplifiers. This ensures your sensitive gear receives clean power without restricting the current flow required by your power amp.
Yes. The unit features two 10A outlets specifically designed to handle high-current demands, ensuring your amplifier maintains its dynamics and punch without being choked by the filtering process.
The trigger ports allow you to integrate the AC-4 into a larger system, enabling the power conditioner to turn on or off automatically when you power up your preamplifier or processor. This simplifies your startup sequence and ensures your entire system powers on in the correct order.
Yes, the unit includes a built-in 15A circuit breaker that provides essential surge protection to safeguard your connected audio equipment from electrical spikes.
By reducing AC line noise by over 20dB, the AC-4 typically reveals more detail, improves soundstage depth, and lowers the noise floor. You aren't changing the sound signature so much as removing the electrical interference that masks the fine nuances of your music.
The AC-4 uses premium Furutech gold-plated sockets, which are highly regarded in the audiophile community for their superior conductivity and secure, long-lasting connection compared to standard wall outlets.
