Product Information

Niagara 5000 Low-Z Power Noise-Dissipation System

AudioQuest continues its war against noise and fortifies its line of noise-dissipation systems with the Niagara 5000. Like all AQ power products, Niagara 5000 exemplifies a comprehensive approach to AC power management—one grounded in verifiable science, representing over 20 years of exhaustive research into AC power products designed for audiophiles, broadcast engineers, and professional-audio applications.

Like the flagship 7000, the Niagara 5000 uses AudioQuest’s patented AC Ground Noise-Dissipation System and extremely wide-bandwidth ultra-linear filtering, which work together to minimize distortion and enable greater resolution from audio, video, and digital components. The Transient Power Correction provides an ultra-low-impedance buffered source for any power amplifier’s power supply, as well as a current reservoir of over 90 amps peak for AC current transients, resulting in tighter, more powerful, and well-defined bass. In addition, AudioQuest's non-sacrificial surge suppression and over-voltage shutdown with automatic reset ensure that a system’s sensitive components are thoroughly protected against both catastrophic and incremental sustained damage. Meanwhile, the Zero Ground-Contamination Technology prevents noise or surge energy present on the AC Line or Neutral from ever connecting to the AC Ground, thereby eliminating what would otherwise create greatly increased distortion and, in some cases, sustained damage to sensitive components. Further, Niagara 5000’s pre-formed AC RF filtering capacitors vastly improve linearity and minimize distortion while dissipating AC line and radio-coupled noise; and, of course, all Niagara Series wiring is direction-controlled for the most efficient dissipation of radio-frequency noise.

So what distinguishes Niagara 5000 from Niagara 7000? The Niagara 5000 forgoes the latter’s patented dielectric-biased symmetrical power isolation transformers. These isolation transformers contribute greatly to Niagara 7000’s state-of-the-art design, enabling the very best means of dissipating common-mode AC line and radio frequency noise from the power that feeds low-current source components. However, many custom-install, pro-audio, or video components simply require greater current capacity than can be had through either of the 7000’s isolation trans­former (source component) output power banks. (Additionally, a small percentage of components may prefer the grounding scheme utilized for the Niagara 5000, as it will allow a greater range of circuits to work harmoniously without the need to connect a source component to the high current bank.)

Far more than a high-value proposition, AudioQuest’s Niagara 5000 delivers 90% of the source-component performance of the flagship 7000 and 100% of the amplifier performance. With the Niagara 5000, you can finally experience and fully enjoy the clarity, dimensionality, frequency extension, dynamic contrast, and sheer grip your systems have always been capable of achieving—now with greater flexibility, even within the most complex system applications.


  • Patented Ground-Noise Dissipation System: Yields lower distortion and greater resolution from audio, video, and digital components with grounded AC cords/circuits
  • Transient power correction: Provides power amplifiers a current reservoir of over 90 amps peak (up to 25mS) for AC current transients
  • Ultra-linear noise-dissipation technology: AC differential and common-mode filtering with linear response, optimized for varying line and load impedance, assures superior resolution for audio, video, and digital signals
  • Ultra-linear AQ-formed AC RF filtering capacitors: Vastly improves linearity and minimize distortions, while dissipating AC line and radio-coupled noise
  • Direction-controlled ultra-low-resistance solid wiring: Optimized for the highest efficiency noise-dissipation of harmful distortion-causing radio frequencies

AudioQuest Niagara 5000
I love it. I was shocked at how handsome a piece it is in real looking thing in my audio rack. Works fine, no issues. Still looking to upgrade the power cord for it soon. Don't hesitate, get one...

Should the Hurricane HC Power cord be used to power the AQ 5000 from the wall to the unit? Or use a Thunder or Tornado cord instead.? Which yields the best results?
Jerome J on Mar 12, 2020
  Thanks for your question. AudioQuest owners manual states: Once the Niagara 5000 is placed, an appropriate 20-amp-rated AC cord must be connected to the rear panel AC inlet (IEC-C20) connector. The AC cord must have an IEC-C19 female end connector and a grounded male 120VAC Edison/NEMA plug for use in North America or Taiwan. We highly endorse the use of any AudioQuest NRG Series 20-amp-rated AC cord as the Niagara-5000s Ground-Noise Dissipation technology relies on its use, but the Niagara 5000 will function adequately with any appropriate AC cord that meets the aforementioned requirements.
Is it recommend to upgrade your wall outlets to a 20 Amp NRG Edison outlet for use with the Audioquest Niagara 5000?
Jerome J on Mar 12, 2020
  Thanks for your question. The AudioQuest Niagara 5000 owners manual states: Ideally, the power source to which the Niagara 5000 is connected should be adequate for use at 120V single phase nominal voltage, 20 amps (current capacity RMS). The manual makes no reference to upgraded wall outlets.
