w/ Linear Noise-Dissipation & Non-Sacrificial Surge Protection

The Niagara 5000 features our patented AC Ground-Noise Dissipation, the widest bandwidth-linearized AC filter in the industry, and our unique passive/active Transient Power Correction Circuit. Boasting an instantaneous current reservoir of over 90 amps peak, the Niagara 5000 is specifically designed for today’s current-starved power amplifiers. Many AC power products featuring “high-current outlets” merely minimize current compression; the Niagara 5000 corrects it.


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.

Groundbreaking Technology for Superior Performance
The Niagara 5000 utilizes AudioQuest’s patented AC Ground Noise-Dissipation System and ultra-linear filtering to minimize distortion and extract greater resolution from audio, video, and digital components. Our Transient Power Correction ensures an ultra-low impedance buffered source for power amplifiers, providing over 90 amps peak for AC current transients, resulting in tighter, more powerful, and well-defined bass.

Unmatched Protection for Your Equipment
Our non-sacrificial surge suppression and over-voltage shutdown with automatic reset guarantee thorough protection against both catastrophic and incremental sustained damage to your system's sensitive components. With Zero Ground-Contamination Technology, we prevent noise or surge energy from ever connecting to the AC Ground, eliminating distortion and, in some cases, sustained damage to sensitive components.

Elevated Performance with Advanced Features
The Niagara 5000 features pre-formed AC RF filtering capacitors to enhance linearity and minimize distortion while dissipating AC line and radio-coupled noise. Additionally, all Niagara Series wiring is direction-controlled for 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 system has always been capable of achieving—now with greater flexibility, even within the most complex system applications.
