AudioQuest - Niagara 3000 Power Conditioner

AudioQuest Niagara 3000 Power Conditioner


Optimized for remarkably effective dissipation of noise while boasting a 55A peak transient current reservoir to stop current compression, the AudioQuest Niagara 3000 Low-Z Power Noise-Dissipation System power conditioner brings flagship Niagara technology within reach to more users by way of its more accessible price.


Insert Niagara 3000 into your audio chain and hear deep silences, dynamic freedom, outstanding ambient retrieval, and accurate delineation of instruments and musicians in space. The difference between what you experienced before and after Niagara 3000 might shock you. True to AudioQuest tradition, this baby comes loaded.


No shrinking violet, the U.S.A.-made Niagara 3000 features 15A (RMS) capacity, AudioQuest's patented Ground Noise-Dissipation System, Transient Power Correction, Level-X linear filtering, seven NRG Series outlets, and more – all for nearly a third of the cost of its top-of-the-line sibling, Niagara 7000. Plus, the 25-pound unit's rack-friendly dimensions (17.5 x 3.45 x 17.5 x 15.2 inches (HWD)) make it a go-to, high-performance option for both audiophile and custom applications.


When plug-in your gear to Niagara 3000, you may notice its NRG-Series AC outlets not only feature superior grip and lower resistance thanks to beryllium copper, they also include thick hanging-silver plating to ensure the lowest impedance at radio frequencies. And like all Niagara Series products, Niagara 3000 has direction-controlled, ultra-low-resistance solid wiring and filter inductors optimized for the high-efficiency noise-dissipation of radio frequencies.



"My sonic priorities were different in the past – realistic midrange, warmth, unlimited soundstages – but now I realize that silence is more important than any of that. Noise suppression is vital to the enjoyment of music – nothing else matters if you don't get this right first. With the AudioQuest Niagara power conditioners in my system, I've come to expect low noise and distortion, more so than ever before."
– Marc Phillips, Part-Time Audiophile


"With the Niagara 3000 in place, it was now possible to experience the delicacies and dynamics of this music to a degree previously unheard."
– Tom Gibbs, Stereophile

The Philosophy and Technology Behind Niagara 3000


For AudioQuest, honoring the source is never a matter of simply using premium audiophile-grade parts or relying on a proprietary technology – common approaches within our community. The company realizes that true audio/video optimization is never a matter of any one secret or exotic circuit. When it comes to noise filtering 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. Niagara 3000 features AudioQuest's patented AC Ground Noise- Dissipation System, the widest bandwidth-linearized AC filter in the industry, and a unique passive/active Transient Power Correction Circuit.


Boasting an instantaneous current reservoir of over 55 amps peak, the Niagara 3000 is specifically designed for today's current-starved power amplifiers. Many AC power products featuring "high-current outlets" merely minimize current compression. Niagara 3000 corrects it.


Though it's easy to tout a given technology, it's quite another thing to create a solution that is consistent, holistic, functional, and that honors verifiable science. It's not enough to reduce AC line noise and its associated distortions at just one octave, leaving vulnerable the adjacent octaves and octave partials to noise, resonant peaking, or insufficient noise reduction.


Consistency is key. We should never accept superior resolution in one octave, only to suffer from masking effects a half-octave away and ringing artifacts two octaves from there. This is the principal criterion for AudioQuest's Low-Z Power Noise-Dissipation System.


Niagara 3000 represents over 20 years of exhaustive research and proven AC power products designed for audiophiles, broadcast engineers, and professional-audio applications.


Every conceivable detail has been addressed: In the Niagara 3000, you'll find optimized radio-frequency lead directionality, capacitor run-in 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.
