Niagara 7000

"Niagara 7000—a power conditioner that joins a few others at the head of the class." -Michael Fremer NIagara 7000 review

"The musical improvements that result from using the Niagara 7000 to drive some or all of your system can be as fundamental as they are significant. It will make your system sound better, but more importantly, it will make it more engaging and more rewarding" -Roy Gregory Niagara 7000 review

AudioQuest's Niagara 7000 Low-Z Power Noise-Dissipation System is a complete rethinking of AC power filtration, designed by one of the field’s foremost experts, Garth Powell. In designing Niagara 7000, Audioquest aimed to successfully address problems that prevent today’s audio/video components from achieving their potential. Due to the great increase in airborne and AC-line-transmitted radio signals, combined with overtaxed utility lines and the ever-increasing demands from high-definition audio/video components, a complete rethinking of AC power technology is needed to provide our A/V systems with the power required to fulfill their potential.

Through differential sample tests and spectrum analysis, it can be proven that up to a third of a high-resolution (low-level) audio signal can be lost, masked, or highly distorted by the vast levels of noise riding along the AC power lines that feed our components. This noise couples with the signal circuitry as current noise and through AC ground, permanently distorting and/or masking the source signal. Our systems’ sensitive components need better alternating current.

Audio/video optimization is never a matter of any one secret or exotic circuit. When it comes to noise dissipation for AC power, many approaches can yield meaningful results. However, these approaches may also impart ringing, current compression, and non-linear distortions that can render the cure worse than the disease. While there currently exist a number of AC power conditioners, isolation transformers, regeneration amplifiers, and battery back-up system topologies, Niagara 7000 takes a holistic, science-based approach to AC power technology and represents a comprehensive solution to the ever-increasing noise that plagues our power lines.

In the Niagara 7000, you’ll find optimized radio-frequency lead directionality, run-in capacitor forming technologies developed by Jet Propulsion Laboratories and NASA, and AC inlet and outlet contacts with heavy silver plating over extreme-purity copper assuring the tightest grip possible.

The Niagara 7000 uses Audioquest's patented AC Ground-Noise Dissipation, the world’s first Dielectric-Biased AC Isolation Transformers, and the widest bandwidth-linearized noise-dissipation circuit in the industry. Their unique passive/active Transient Power Correction Circuit features an instantaneous current reservoir of over 90 amps peak, specifically designed for today’s current-starved power amplifiers. Most AC power products featuring “high-current outlets” merely minimize current compression; the Niagara 7000 corrects it.
